Application overview Application Type Description VL160X System protection The releases for system protection are designed to protect cables and non-motorized loads against overload and short-circuit. VL160 VL250 VL400 VL630 VL800 VL125 3- and 4-pole molded case circuit breakers VL1600 VL160 VL250 VL400 Generator protection The overload and short-circuit releases can be used for optimized protection of generators. VL630 VL800 VL125 VL1600 3- and 4-pole molded case circuit breakers VL160 VL250 VL400 VL630 Motor protection The overload and short-circuit releases are designed for optimal protection and direct starting of three-phase AC squirrel-cage motors. The molded case circuit breakers for motor protection have phasefailure sensitivity and a thermal image that protects the motor against overheating. The adjustable time lag class enables users to adjust the overload release to the startup conditions of the motor to be protected. 3-pole molded case circuit breakers 3VL IEC molded case circuit breakers 20 System Manual, 11/2013, 110 0110 - 02 DS 03 Product description 3.2 Application overview Application Type Description VL160 Starter combination Starter combinations consist of: molded case circuit breaker + contactor + overload relay. The molded case circuit breaker handles short-circuit protection and the isolating function. The contactor has the task of switching the load feeder normally. The overload relay handles overload protection that can be specially matched to the motor. The molded case circuit breaker for starter combination is therefore equipped with an adjustable and instantaneous short-circuit release. VL250 VL400 VL630 3-pole molded case circuit breakers VL160X VL160 VL250 VL400 VL630 Non-automatic air circuit breakers These molded case circuit breakers are used as incoming circuit breakers, main switches or isolating switches without overload protection. They have fixed short-circuit releases so that back-up fuses are not necessary. VL800 VL1250 3- and 4-pole molded case circuit breakers VL1600 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 21 Product description 3.3 Configuration 3.3 Configuration 3.3.1 Functional principle Mechanical design All 3VL molded case circuit breakers have a trip-free mechanism that ensures the trip process is not prevented even if the operating mechanism is blocked or manually held in the "ON" position. The contacts are opened and closed by a toggle lever positioned in the center. This is attached to the front side on all molded case circuit breakers. All 3VL molded case circuit breakers are "joint trip units". This means all contacts open or close simultaneously when the molded case circuit breaker toggle lever is moved from "OFF" to "ON" or from "ON" to "OFF", or when the tripping mechanism is activated by an overcurrent or with the help of the auxiliary trips (shunt release or undervoltage release). Current limiting The 3VL molded case circuit breakers are designed on the principle of magnetic repulsion of the contacts. The contacts open before the expected peak-value of the short-circuit current is reached. Magnetic repulsion of the contacts very considerably reduces the thermal load I2t as well as the mechanical load resulting from the impulse short-circuit current IP of the system components that occur during a short-circuit. You can find more information in the chapter Use in motor protection (Page 64). 3.3.2 Subdivision according to power ranges VL160X molded case circuit breakers The most important components of the VL160X molded case circuit breakers are the three current paths with the incoming and outgoing terminals. The fixed and movable contacts are arranged in such a way as to guarantee magnetic repulsion of the contacts. In conjunction with the arcing chambers, a dynamic impedance is generated that causes current limitation. This reduces the damaging effects of excessively high values I2t and Ip. The overcurrent release is a factory-installed thermal-magnetic device. It is equipped with fixed or adjustable overload releases and a fixed short-circuit release in each pole. To the right and left of the centrally positioned toggle lever of every SENTRON VL molded case circuit breaker is a double-insulated accessory compartment for installing auxiliary switches or alarm switches as well as shunt releases and undervoltage releases. 3VL IEC molded case circuit breakers 22 System Manual, 11/2013, 110 0110 - 02 DS 03 Product description 3.3 Configuration VL160 to VL630 molded case circuit breakers The arrangement of current paths, contact configuration and switch mechanism of the VL160 to VL630 molded case circuit breakers corresponds to that of the VL160X molded case circuit breaker. The designs diverge with regard to the overcurrent release. The overcurrent releases are available in a thermal-magnetic version and in an electronic version. Thermal-magnetic overcurrent releases are available with adjustable overload releases and short-circuit releases. VL800 to VL1600 molded case circuit breakers The arrangement of the current paths and switch mechanisms is identical to that of the VL160X to VL630 molded case circuit breakers. However, the VL800 to VL1600 molded case circuit breakers are only available in the version with electronic trip unit. As with all electronic trip units for the SENTRON VL molded case circuit breakers from Siemens, the current transformers (one per phase) are accommodated within the overcurrent release enclosure. All 3VL molded case circuit breakers with electronic trip units measure the actual RMS current. This method is the most accurate way of measuring currents in electrical distribution systems with extremely high harmonics. 3.3.3 Thermal-magnetic overcurrent trip units A thermal-magnetic overcurrent release consists of two components - a thermal release for protecting against overload, and a magnetic release for protecting against short-circuit. Both release components are series-connected. Thermal release The thermal release consists of a temperature-dependent bimetal that heats up as a result of the flow of current. This means the release is current-dependent. The heating of the bimetal strip depends on the ambient temperature of the molded case circuit breaker. All current values specified for 3VL for thermal-magnetic releases refer to an ambient temperature of 40 C. Where ambient temperatures deviate from this, the values in the tables in the chapter Use at altitudes above 2000 meters (Page 142) are to be used. 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 23 Product description 3.3 Configuration Magnetic release The magnetic release comprises a yoke mounting through which a current path runs, and a flap armature that is kept at a distance from the yoke mounting by a tension spring. If a short-circuit current now flows along the current path, the magnetic field thus generated causes the flap armature to be moved towards the yoke mounting against the opposite force of the tension spring. The release time is almost current-independent and instantaneous. The flap armature releases the switching lock and thus opens the switching contacts before the short-circuit current can reach its maximum; a current limiting effect is thus achieved. Immediately after release, the flap armature is moved back to its starting position by the opposite force of the tension spring. 3.3.4 Electronic overcurrent trip unit (ETU) Electronic trip units (ETUs) In contrast to thermal-magnetic releases/trip units (TMTUs) where the overcurrent trip is caused by a bimetal strip or magnetic release, electronic trip units (ETUs) use electronics with current transformers. The ETU captures the actual currents and compares them with the default specifications. All 3VL molded case circuit breakers with electronic overcurrent trips measure the actual RMS current (true RMS). This is the most accurate method of measuring. ETUs are available from the VL160 molded case circuit breaker up to and including the VL1600. The VL800, VL1250 and VL1600 molded case circuit breakers are only available in the version with electronic trip unit. Configuration The electronic overcurrent tripping system consists of: 3 to 4 (3-pole or 4-pole) current transformers that also provide their own power supply. This means an external auxiliary voltage is not required. Evaluation electronics with microprocessor Tripping solenoid In all versions with electronic trip units for the 3VL molded case circuit breakers, the current transformers are located in the same enclosure as the trip unit. At the output of the electronic overcurrent tripping module, there is a tripping solenoid that trips the molded case circuit breaker in the event of an overload or short-circuit. In all electronic trip units, the tripping solenoid is located within the trip unit, except in the shipbuilding ETUs of sizes VL160 and VL250. In these ETUs, the tripping solenoid is located in the left accessories compartment. Power supply The protection functions of the electronic trip unit are guaranteed without additional auxiliary voltage. The overcurrent releases are supplied with energy via internal current transformers. The protection function is set via rotary encoding switches on the ETU or via an LCD display. 3VL IEC molded case circuit breakers 24 System Manual, 11/2013, 110 0110 - 02 DS 03 Product description 3.3 Configuration In the case of an LCD display, the electronic trip unit must be activated. This requires a 3phase (3-pole) load current of at least 20% or, in the case of a single-phase (single-pole) load, 30% of the relevant rated current of the molded case circuit breaker. If this load current is not available, the necessary auxiliary energy can be supplied via a battery power supply (order no. 3VL9000-8AP01). With communication-capable, molded case circuit breakers, the trip unit is powered by means of the COM20 or COM21 module. Battery supply device The handheld tester for electronic trip units is used as a local test device for the 3VL molded case circuit breakers with electronic trip unit, and it can be used as an external voltage supply for the electronic trip units (ETU and LCD-ETU). The portable battery power supply is fed by two standard 9 V block batteries. Test function: Test tripping Figure 3-3 Battery supply device 4-pole molded case circuit breakers The four-pole molded case circuit breakers for system protection can be supplied in all 4 poles with or without current transformers. The trip units in the 4th pole (N) can be set to 50% or 100% of the current in the 3 main current paths dependent on the size, so that safe protection of the neutral conductor can be guaranteed even with a reduced cross-section. In the case of LCD-ETUs, the neutral conductor protection can be adjusted in steps from 50% to 100% or switched off. 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 25 Product description 3.4 Mechanical operating mechanisms 3.4 Mechanical operating mechanisms 3.4.1 Toggle lever operating mechanism In the basic version, the 3VL molded case circuit breakers have a toggle lever as actuator, which is also an indicator of the switching position. The "Tripped" position is also displayed in addition to the "ON" and "OFF" positions. The toggle lever goes to the "tripped" position when the internal trip mechanism is activated by an overcurrent situation, e.g. overload or short-circuit, or if the Test key is operated. Activation by an undervoltage release or shunt release will also cause the toggle lever to move to the "Tripped" position. The toggle lever must be returned to the "OFF/RESET" position before the molded case circuit breaker can be activated again. This enables the internal release mechanism to be reset. 3VL molded case circuit breakers with toggle lever operation comply with the "Network disconnecting device" condition (5.3.2 Section c) and 5.3.3) according to DIN EN 60204-1 (VDE 0113-1) in conjunction with a locking device.

02 DS 03 43 Functions 4.1 Protection functions 4.1.5 Differential current protection with RCD module The molded case circuit breaker with differential current protection is very often used to implement a double function: Protection of systems against overload and short-circuit currents. Protection of cables and electrical equipment against damage from ground faults. The SENTRON VL RCD modules are offered as accessories for the VL160X, VL160, VL250 and VL400 molded case circuit breakers with thermal-magnetic overcurrent releases. This combination is called molded case circuit breaker with differential current protection of type A. Type A means tripping is guaranteed both in the case of faults in sinusoidal alternating currents and in the case of faults in pulsating direct currents. These units have an adjustable trip time delay t. The values for the rated fault current In can also be adjusted. In a fault-free system, the sum of the currents in the summation current transformer of the RCD module is zero. A ground fault current occurring in the circuit as the result of an insulation fault produces a differential current that induces a voltage in the secondary winding of the current transformer. The evaluation electronics monitors the induced voltage and transmit a trip command to the RCD trip unit if the trip criterion is met. The molded case circuit breaker with differential current protection combination is designed to open he molded case circuit breaker contacts if the differential current reaches a specific value. Note The RCD module can only be combined with 3VL molded case circuit breakers with thermalmagnetic overcurrent release. It cannot be combined with a molded case circuit breaker with ETU. 3VL IEC molded case circuit breakers 44 System Manual, 11/2013, 110 0110 - 02 DS 03 Functions 4.1 Protection functions Standard features Mechanical trip display: The Reset button on the RCD pops out when the RCD module trips the molded case circuit breaker. Reset button: This must be manually reset after the molded case circuit breaker has been tripped by the RCD module. The molded case circuit breaker can only be reset and switched on again after the RCD module has been reset. Cover: Modifiable settings for t and In. A sealable transparent cover is available for preventing modification. The RCD module has three LEDs: - Green LED flashes: "Active" -> indicates that the RCD module is functional - Yellow LED flashes: The fault current is between 25% < I< 50% of the set In value - Red LED flashes: The fault current I is greater than 50% of the set In value Test button: The functionality of the RCD module is checked with the test button. If the test button is pressed, differential current is simulated on a test winding attached to the summation current transformer. When functioning correctly, the RCD module must trip the molded case circuit breaker. The test button must be pressed for at least the set delay time t. A line disconnector: - makes it possible to disconnect the evaluation electronics of the RCD module from the circuit without removing the primary cable or the busbars (e.g. before insulation tests). - Limitation of the maximum RMS withstand voltage to an RMS value of 3500 V AC for this feature, i.e. the RMS value of the voltage for max. 60 seconds for one insulation test must not exceed 3500 V. Protection function from 50 V AC between phase and neutral conductor The RCD module has a surge current withstand capability of Ipeak = 2000 A. The standard surge wave is defined as 8 / 20-s waveform. The RCD module does not trip in the case of making currents. t 0 Irms = 3000 A t 60ms Ipeak = 20 x In x 2 The molded case circuit breaker with differential current protection combination can be supplied from both sides. Matching molded case circuit breaker standard accessories - covers, phase barriers, wire connectors. 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 45 Functions 4.1 Protection functions Special features of the VL160X The molded case circuit breaker is tripped via an electromagnetic trip relay installed in the breaker accessories compartment to the left of the toggle lever. The trip unit in the molded case circuit breaker is connected to the RCD module and receives a trip command when the preset fault currents are reached. Internal accessories can still be installed to the right of the toggle lever. The Reset button functions in exactly the same way as on the RCD modules VL160 to 400 and is accessible via the molded case circuit breaker accessories cover supplied with this module. Note Motorized operating mechanism with stored energy mechanisms and rotary operating mechanisms cannot be installed with this product. Special features of VL160, VL250, VL400 The molded case circuit breaker is tripped by means of a direct-acting tappet from the RCD module to the system protection switch. The electromagnetic trip unit is integrated in the RCD module. The Reset button pops out beyond the surface of the RCD module cover to indicate that the RCD module has tripped the system protection switch. This unit prevents the system protection switch contacts from closing before the Reset button of the RCD module has been manually reset. This has the same design as the system protection switch accessories including the accessories for external operating mechanisms as well as for fixed-mounted assembly, plug-in assembly and withdrawable assembly. An auxiliary switch (changeover contact) is available. The contacts change status when the RCD module trips the system protection switch. Remote tripping is supported. The customer connects a switch (NO contact) to terminals X13.1 and X13.3 via a twisted-pair cable. The switching contact must have a minimum switching capacity of 5 V/1 mA (e.g. SIEMENS 3SB3). If the NO contact is actuated, the RCD module trips. The connection terminals X13.1 and X13.3 are galvanically isolated from the system by means of a transformer (functional extra low voltage, FELV). The maximum trip time of the molded case circuit breaker with differential current protection is 50 ms regardless of the set trip time delay t. In special cases, such as routing of the cable outside, ensure by means of suitable cable routing or protection measures that the amplitude of overvoltages (e.g. overvoltages due to thunderstorms) between the conductor and ground is limited to 2.5 kV. 3VL IEC molded case circuit breakers 46 System Manual, 11/2013, 110 0110 - 02 DS 03 Functions 4.1 Protection functions Special requirements Every RCD module requires a separate cable for remote tripping. It is not possible to use one cable and connect two or more RCD modules in parallel. It is possible to use two or more switches in parallel for remote tripping of an RCD module. Use an unshielded or shielded twisted-pair cable with a maximum capacitance of 36 nF as well as a maximum resistance of 50 Ohms (total length = out and back). With a shielded cable, the shield must not be applied to the PE conductor of the system. A separate conductor must connect terminal X13.2 with the ground busbar (E or PE). This connection is recommended for the prevention of electrostatic charge on the remote tripping cable. This applies in particular when long cables (> 10 m) are used. If this is not the case, the remote tripping cable is isolated.

Apart from the test current circuit, the RCD module is unrestricted in functionality if at least 2 conductors are connected. When connecting the RCD module, you only have to ensure that the test current circuit connected to current path 1-2 and 3-4 (marking) is functioning or is supplied with power. The following connections are possible in 2-pole operation: 2-pole operation with a 3-pole molded case circuit breaker Connection of the network to current path 1-2 and 3-4 (any incoming supply side) Figure 4-3 3-pole RCD Note Single-pole load Series connection of the current paths is not necessary in the case of single-pole load. 3VL IEC molded case circuit breakers 48 System Manual, 11/2013, 110 0110 - 02 DS 03 Functions 4.1 Protection functions 2-pole operation with 4-pole molded case circuit breakers Connection of the network to current path 1-2 and 3-4 (any incoming supply side) or connection of the network to current path 1-2 and N; however, a jumper is required here from N to current path 3-4 (on the input or output side) Figure 4-4 4.1.7 4-pole RCD Ground-fault protection Ground fault trip "G" (ground fault overcurrent protection) captures fault currents flowing to ground that can cause fires in the plant. Several molded case circuit breakers connected in series can be assigned time-graded discrimination by means of the adjustable delay time. The delays can be reduced to 100 ms by using a ZSI system. Measurement method 1: Vectorial summation current formation Ground fault detection in balanced systems The three phase currents are evaluated using vectorial summation current formation.

Only the ground-fault current is measured for the 3-pole circuit breakers. In the case of the 4-pole circuit breakers, the neutral conductor overload protection is also measured. The overcurrent release calculates the ground-fault current using the vectorial summation of the three phase currents and the neutral conductor current. The 4th current transformer of the neutral conductor is installed internally in the case of 4pole molded case circuit breakers.

If voltage is not applied to the releases, operation of the circuit breaker will result in no-load switching. The undervoltage release trips the molded case circuit breaker when the voltage fails. Tripping can occur within a voltage range of 0.7 to 0.35 x US. Tripping occurs under 0.35 x US. Re-closure of the molded case circuit breaker contacts is only possible once the voltage has reached a value of 0.85 to 1.1 x US. Undervoltage releases can be installed for electronic locking. Undervoltage release Undervoltage releases are installed in the right accessory compartment of the 3VL molded case circuit breakers. 3VL IEC molded case circuit breakers 52 System Manual, 11/2013, 110 0110 - 02 DS 03 Functions 4.2 Internal accessories 4.2.3 Shunt release Molded case circuit breaker with shunt release The molded case circuit breaker with shunt release is used for remote protection. The shunt release is used for remote tripping of the molded case circuit breaker. The molded case circuit breaker is tripped by applying the operating voltage at the shunt release. It is designed for short-time operation and is therefore equipped with an interrupt contact for self-protection. Shunt releases are installed in the right accessory compartment of the 3VL molded case circuit breakers. Shunt release 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 53 Functions 4.2 Internal accessories 4.2.4 Auxiliary switches and alarm switches Auxiliary and alarm switches are used to indicate the switching status of the molded case circuit breaker Auxiliary switches show the position of the main contacts ("ON" or "OFF"). Alarm switches transmit a signal when the molded case circuit breaker trips due to a shortcircuit or overcurrent, or when the shunt release, undervoltage release, test button, or RCD module trips.

The following applications are possible: Leading auxiliary switch for switching from "ON" to "OFF" Leading auxiliary switch for switching from "OFF" to "ON" Each version, leading auxiliary switch for switching on and off, can be equipped with one or two changeover switches. The connecting cables of the auxiliary switches are 1.5 m long.

Leading auxiliary switch for switching off (leading NC contact) Application example: In applications with thyristors, it is necessary to reset the power electronics of the converter before the main circuit is switched off. Molded case circuit breakers with leading auxiliary switches create a leading signal that enables selective deceleration of the thyristor. 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 55 Application planning 5.1 5 Use with frequency converters Combination of frequency converter and 3VL molded case circuit breaker 3VL molded case circuit breakers can be used as protection devices on the primary side in systems in which frequency converters, variable-speed drives, and electronic motor control devices are used. The thermal-magnetic and electronic trip units of the 3VL molded case circuit breakers can be used in these applications. On account of RMS measurement, the SENTRON VL trip units are not influenced by harmonics.

In reactive power compensation, also called power factor correction, the undesired reactive power of loads in AC systems is reduced. Reactive power compensation is usually performed by compensating inductive reactive power with capacitive load. A combination of fixed and central compensations are used depending on the design of the low-voltage system and the loads involved. Molded case circuit breaker for protecting and switching capacitor banks According to the relevant standards DIN VDE 0560 Part 41 / EN 60831-1 / IEC 70, capacitors must operate under normal operating conditions with the current's RMS value being up to 1.3 times the rated current of the capacitor. In addition, a further tolerance of up to 15% of the real value of the power must be taken into consideration. The maximum current with which the selected molded case circuit breaker can be constantly loaded, and which it must also be able to switch, is calculated as follows: IN max = IN x 1.5 (RMS value, RMS current) Important values for selecting the molded case circuit breaker More detailed information in the technical data: Capacitor banks (Page 152) Abbr. Designation Qn Capacitor bank rated power in kVA UN Rated voltage of the capacitor IN Rated current of the capacitor bank IN max Maximum expected rated current Ii Value for setting the instantaneous short-circuit release IR Value for setting the inverse-time delayed overload release The following applies: IN = QN / (3 x UN) IR = INmax = IN x 1.5 Ii> 9 x IR (minimum) 3VL IEC molded case circuit breakers 58 System Manual, 11/2013, 110 0110 - 02 DS 03 Application planning 5.3 Transformer protection on the primary side 5.3 Transformer protection on the primary side The molded case circuit breaker as transformer protection on the primary side When switching on low-voltage AC transformers, the extremely high inrush current peaks place special demands on the trip unit or on the making capacity of the molded case circuit breakers if these are also used to switch the transformer. For most applications, an inrush current of 20 to 30 times the rated operating current is expected in practice and must be taken into account when selecting the molded case circuit breakers. The maximum short-circuit current Ik of the 3VL molded case circuit breakers is 11 x In (rated current). A molded case circuit breaker in the lower setting range must therefore be used for transformer protection on the primary side. Example: A transformer with 500 A rated current; 20 times the inrush current Selected: ETU with In = 1000 A; setting range 0.4 - 1 x In = 400 A to 1000 A 50% of In = 500 A; Ii = 11 x In = 1000 A x 11 = 11000 A = 22 x current setting Note Disconnection of molded case circuit breaker It is imperative to ensure that the minimum short-circuit current Ikmin in accordance with VDE 0100 can be disconnected using a protection facility (e.g. molded case circuit breaker). The 3VL molded case circuit breaker can be disconnected using the short-time-delayed short-circuit release (S), e.g. a 3VL with an ETU20, where it is possible to set the delay time to up to 500 ms depending on the duration of the inrush current. The short delay "bridges" the inrush current peak and the short-circuit protection can then respond at low current values after a delay. CAUTION Molded case circuit breaker with phase failure protection Molded case circuit breakers with phase failure protection must not be used. Their trip units have protection against unbalanced network load which cannot be deactivated and can lead to unintentional trips. 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 59 Application planning 5.4 Use in DC systems 5.4 Use in DC systems The 3VL molded case circuit breakers 160X to VL630 with thermal overload and magnetic short-circuit trip units (TMTU) are suitable for use in DC systems. The 3VL 160 to VL1600 molded case circuit breakers with electronic trip units (ETUs) are not suitable for switching DC. Selection criteria for molded case circuit breakers The following are the most important criteria for selecting the optimal molded case circuit breaker for protecting a DC system: The rated current determines the size of the molded case circuit breaker. The rated voltage determines the number of series-connected poles required for breaking - 3 or 4 poles. The maximum short-circuit current at the connection point determines the breaking capacity. The type of supply determines the circuit design. Ampacity of current path The rated current values are the same for both DC and AC applications. Switching DC currents In AC circuits, arc quenching is facilitated because the current flows through zero. These preconditions do not apply for DC. For this reason, a high arc voltage must be developed to interrupt the direct current. Therefore, the breaking capacity depends on the arc quenching method and the line voltage. Several switching contacts can be connected in series in order to achieve a higher arc voltage. Furthermore, the effects to be expected in the event of a ground fault or double ground fault must also be considered. Setting of the trip values Thermal overload release ("L" release): Same settings as in 50 / 60 Hz systems. Instantaneous short-circuit release ("I" release): The threshold values of the instantaneous short-circuit release ("I" release) increase by 30 to 40%. See also Chap. 9 3VL IEC molded case circuit breakers 60 System Manual, 11/2013, 110 0110 - 02 DS 03 Application planning 5.4 Use in DC systems Example: 4000 A + 30% = 5200 A There is also a tolerance of 20% At the Ii = 4000 A setting, the instantaneous short-circuit release responds at approx. 5200 A 20%. As the current has to flow through all of the conducting paths, the following connections are recommended in order to satisfy the thermal tripping characteristics.

The 3VL8 and 3VL7 (1250 A) cannot be used in an IT system. The 3VL molded case circuit breakers for system protection from SIEMENS, optionally available with thermal overload and electromagnetic short-circuit releases, or electronic trip units, are suitable for use in IT systems. The molded case circuit breakers also meet the requirements of IEC 60947-2 Annex H (EN 60947-2, Annex H). The respective options are required here, and the necessary safety clearances (ventilation clearances) must be observed. Selection criteria for molded case circuit breakers The devices are always dimensioned and selected independently of the relevant system type. The circuit breaker is always selected in accordance with the maximum short-circuit current in the IT system. The device is selected in accordance with the relevant Icu values of the 3VL molded case circuit breaker. The neutral conductor is not grounded by definition in the IT system. The system operator ensures that no double ground fault can occur on the input or output side of the molded case circuit breaker. In this case, the switching capacity of the IT systems remains unchanged. If this is not guaranteed, the values in accordance with the standard IEC 60947-2 Annex H apply for single-pole short-circuits. 3VL IEC molded case circuit breakers 62 System Manual, 11/2013, 110 0110 - 02 DS 03 Application planning 5.5 Use in IT systems Fault situation The most critical fault for molded case circuit breakers in ungrounded IT systems is a double ground fault on the infeed and load side of the molded case circuit breaker.

Operating principle of the overcurrent releases The tripping characteristic curves of the inverse-time delayed overload releases are specially designed for overload protection of 3-phase AC motors. With the inverse-time delayed overload release "L", the value IR can be set to be 0.4 to 1.0 times the rated current In of the molded case circuit breaker. This occurs in 0.01 increments (e.g. 0.40 / 0.41 / 0.42 ... 0.99 / 1.0 x In), so that the molded case circuit breaker exactly matches the rated current of the motor to provide optimal protection. The current transformers in the 3VL molded case circuit breaker not only measure the load current, they also supply power to the electronic trip unit. No external auxiliary power supply is required. This independence from an external energy supply guarantees a high standard of safety. Area of application Machine tools, manufacturing systems, presses, fans, air-conditioning units and packaging machines all require motors that must be protected. This is the main area of application of the 3VL molded case circuit breakers for motor protection. Trip class The 3VL molded case circuit breakers offer the option of selecting from various trip units with fixed or adjustable trip classes that are suitable for differing motor applications. ETU 10 M This version is equipped with a thermal image, phase failure sensitivity and the fixed trip class 10. ETU 30 M This version is equipped with an adjustable trip class 10 to class 30 in addition to the thermal image and phase failure sensitivity. 3VL IEC molded case circuit breakers 64 System Manual, 11/2013, 110 0110 - 02 DS 03 Application planning 5.6 Use in motor protection ETU 40 M This version enables the parameters and the trip class 5 to class 30 to be configured step by step using a menu on the LCD display that is built into the trip unit. Trip classes Trip class 5 is used for motors that have very simple start-up characteristics (those with a short start-up time and a small mass moment of inertia). The class 30 releases are used to protect motors that have to withstand difficult start-up characteristics (long start-up time and large mass moment of inertia). The motor must be suitable for heavy-duty starting. The trip class must be selected so that it corresponds to the overload factor of the motor under operating conditions. You can find further information at the end of this chapter in the figure "Current-time curve before and after overload, with thermal image". Definition of the trip class The trip class specifies the release time for balanced 3-pole loads, starting from the cold state, with 7.2 times the set current Ir according to IEC 60947-4-1. Combinations with class 10 are normally used. Applications that require a longer start-up time, such as fans with large blade diameters, require a higher trip class. Figure 5-3 ETU with trip classes 5, 10, 15, 20, 30 Tripping characteristic curve for molded case circuit breakers with electronic trip unit. 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 65 Application planning 5.6 Use in motor protection Thermal image All 3VL molded case circuit breakers with electronic trip unit have a "thermal image" which takes the pre-loading of the AC motor into consideration. The tripping times of the currentdependent delayed overload releases are only valid for the unloaded (cold) state. The pre-loading of the 3-phase AC motor must be taken into consideration in order to prevent damage to the motor, e.g. after being frequently switched on without sufficient cooling time. Siemens offers the 3VL molded case circuit breakers with fixed thermal image to provide maximum protection for the motor. Functional principle of the thermal image During operation, a thermal model of the motor is simulated in the ETU. This reduces the response time of the molded case circuit breaker with thermal image such that further overloads cannot damage the motor windings. The motor is switched off within a time limit that is specified by the pre-loading. An overload may also be the switch-on current of the motor. After an overcurrent tripping, the tripping times are reduced in accordance with the tripping characteristic curves. A cooling time defined by the size of the motor is required before the motor can be switched on again. This prevents the motor from being excessively thermally loaded by a current immediately after an overload release occurs. Without "thermal image" With "thermal image" Figure 5-4 Response time of the trip unit after overload release Phase failure sensitivity The "phase failure sensitivity" function is also integrated into the 3VL molded case circuit breaker for motor protection. This ensures that the motor is reliably protected against overheating if a phase interruption or a large fluctuation occurs. The specified operational current IR is automatically reduced to 80% of the set value if the RMS values of the operational currents in the three phases differ by 5 to 50% (depending on release type). Deviations of more than 50% mean the value of the current in the least loaded phase drops to a level below 50% of the maximum loaded phase. 3VL IEC molded case circuit breakers 66 System Manual, 11/2013, 110 0110 - 02 DS 03 Application planning 5.7 Use in unusual environments: 5.7 Use in unusual environments: If the 3VL molded case circuit breakers are to be used outside closed control cabinets or in difficult operating conditions, the following information must be taken into account at the planning stage: Reduction factors under unusual operating conditions Altitude in excess of 2000 meters Temperature above 50 C Frequencies outside the 50 / 60 Hz range Humidity etc. You can find further details in DIN ISO 2533 "Standard Atmosphere". Use at altitudes above 2,000 meters The lower air density at altitudes above 2,000 meters affects the key electrical data of molded case circuit breakers. The table in the Technical data (Page 142) shows the derating factors that have to be taken into account when using the molded case circuit breakers at altitudes above 2,000 m. Use at different ambient temperatures A reduction (derating) of the rated operational current of the 3VL molded case circuit breakers is necessary if the ambient temperature around the molded case circuit breaker exceeds 50 C. The reference temperature is 40 C for molded case circuit breakers with RCD modules or for plug-in / withdrawable versions. The permissible load for various ambient temperatures with reference to the rated operational current of the molded case circuit breaker are shown in the technical data. Furthermore, the following points must be taken into consideration, because each one of these factors can influence the rated operational current and permissible load. Type of molded case circuit breaker (fixed-mounted, plug-in or withdrawable version) Type of main connection (vertical/horizontal busbar, cable) Ambient temperature around the molded case circuit breaker Altitude derating factors Temperature derating factors based on different trip units and connections Increased degree of protection 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 67 Application planning 5.7 Use in unusual environments: Thermal-magnetic overcurrent releases Thermal-magnetic overcurrent releases are calibrated to 50 C. As a result, the tripping times of the thermal overcurrent releases increase for a constant current at low temperatures. To correct the tripping times, the thermal overcurrent release settings must be changed by the factor from the table "Derating factors for thermal-magnetic overcurrent releases" in the technical data (lower settings). Use in systems with other frequencies If low-voltage switching devices designed for 50 / 60 Hz are to be used at other line frequencies, the following points must be taken into consideration: Thermal effects on the system components Switching capacity Service life of the contact system Tripping characteristics of the overcurrent releases Behavior of the accessories Thermal rating of the system components and conductors depending on the line frequency Molded case circuit breakers designed for alternating current of 50 / 60 Hz can be used at lower frequencies for at least the same rated currents. However,the permissible operating current must be reduced at frequencies higher than 100 Hz to ensure the specified temperature rise limits are not exceeded. Influence of temperature and humidity on overcurrent releases The relevant reduction in the rated operating current (derating) of the 3VL molded case circuit breakers is also necessary if the operating temperature of 50 C or 70 C is exceeded at a relative humidity level (non-condensing) of 95%. Thermal-magnetic TM releases Figure 5-5 Thermal-magnetic TM 0 C to +70 C, 95% The SENTRON VL thermal-magnetic releases are designed for use in ambient temperatures up to 70 C and a relative humidity level (non-condensing) up to 95%. The appropriate correction factors must be applied for ambient temperatures above 50 C. You can find more information in Chapter 11.4 "Reduction factors" 3VL IEC molded case circuit breakers 68 System Manual, 11/2013, 110 0110 - 02 DS 03 Application planning 5.8 Use in series connection Electronic trip unit ETU Figure 5-6 Standard ETU -25 C to +70 C, 95% The 3VL electronic trip units are designed for use in ambient temperatures up to 70 C and a relative humidity (non-condensing) up to 95%.

The appropriate correction factors must be applied for ambient temperatures above 50 C. 5.8 Use in series connection In the case of molded case circuit breakers connected in series, the overload and shortcircuit protection is described as "selective" when, from the point of view of the direction of energy flow, only the circuit breaker immediately upstream of the fault trips. Current selectivity The selectivity can be calculated in the overload range by comparing the time/current characteristics. In the short-circuit range, this comparison leads to values that are too low. The reason for this is that the trip unit behaves differently in the case of short-circuit currents compared to its long-term behavior, e.g. in the case of overloads. If the short-circuit currents differ sufficiently at the installation points of two molded case circuit breakers, the instantaneous short-circuit releases can normally be set such that if a short-circuit occurs behind the downstream circuit breaker, only this downstream breaker trips. If the short-circuit currents are approximately the same at the installation points of the breakers, the grading of the tripping currents of the short-circuit releases only enables selectivity up to a specific short-circuit current . 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 69 Application planning 5.8 Use in series connection This current is referred to as the selectivity limit. If the values determined by the short-circuit current calculation (e.g. according to IEC / EN 60909, DIN VDE 0102) at the installation point of the downstream circuit breaker are below the selectivity limit listed in the respective table for the selected combination, selectivity is guaranteed for all possible short-circuits at the installation point. If the calculated short-circuit current at the mounting point is higher than the selectivity limit, selective tripping by the downstream circuit breaker is only ensured up to the value listed in the table. The engineer must judge whether the value can be considered to be sufficient because the probability of, for example, the maximum short-circuit occurring is low. Otherwise, a circuit breaker combination should be chosen whose selectivity limit lies above the maximum short-circuit current. Time selectivity Selectivity can be achieved by time selectivity up to the threshold values of the instantaneous short-circuit release. To achieve this, the upstream circuit breaker requires delayed short-circuit releases, so that in the event of a fault, only the downstream circuit breaker will disconnect the faulted system component from the supply. Both the tripping delays and the tripping currents of the short-circuit releases are staggered. Zone-selective interlocking - ZSI Zone-selective interlocking (ZSI) has been developed by SIEMENS for the 3VL molded case circuit breakers to prevent long, undesired release times when several molded case circuit breakers are connected in series. ZSI enables the tripping delay to be reduced to 50 ms for the circuit breaker upstream from the location of the short-circuit. When selecting, ensure that the molded case circuit breaker can handle the initial balanced short-circuit current IK at the installation point. The following are required for the ZSI function: A COM20 or COM21 communication module A communication-capable ETU You can find further details in the following manuals: "SENTRON WL and SENTRON VL circuit breakers with communication capability PROFIBUS" (Order No. A5E01051347) "SENTRON WL and SENTRON VL circuit breakers with communication capability Modbus" (Order No. A5E02126886) 3VL IEC molded case circuit breakers 70 System Manual, 11/2013, 110 0110 - 02 DS 03 Application planning 5.9 Use in transfer control system 5.9 Use in transfer control system The 3KC ATC5300 transfer control device (automatic transfer control device) together with two 3VL molded case circuit breakers with motorized operating mechanism (MO), forms the transfer control system that can be used to switch automatically or manually between two low-voltage power distribution systems. Overview of the 3KC ATC5300 transfer control device The ATC5300 controls the transfer between two power supplies fully automatically, while taking account of set limit values and delay times. It detects fluctuations occurring in the main power supply quickly and switches to the standby power supply. The control device only switches to the standby power supply after it has ensured that the standby supply is providing the required quality. The devices switch back to the main power supply, taking into consideration the set parameters, once the required quality has been restored. If the standby power supply and/or the main power supply is fed by a generator, the control device also offers a wide range of settings, such as a generator lead time, generator delay time, and generator start test at specified times. The ATC5300 can be used for the following applications: Supply of UPS (uninterruptible power supply) systems Emergency supply of public buildings, hotels and airports Supply of data centers and communication systems Supply of industrial processes requiring a high level of operational continuity.

A minimum load current of approximately 20% of the relevant rated current In of the molded case circuit breaker is required. Note The factory-set "LCD-ETU" with the maximum settings for the overload release and the short-circuit release must be adapted during commissioning. Changing the parameters for the overload and short-circuit releases during operation to a value below the current operating value causes instantaneous tripping. If this minimum load current is not available, the required auxiliary power can be supplied using the 3VL9000-8AP01 hand-held tester. In molded case circuit breakers with communication capability, the trip unit is supplied with power by the COM20/21 Release 2. 3VL IEC molded case circuit breakers 118 System Manual, 11/2013, 110 0110 - 02 DS 03 Parameter assignment / addressing 9.1 9 Setting the parameters Settings on the ETU Note Adjusting settings The overcurrent release is preset with the maximum settings for the overload release and the short-circuit release. You must adjust these settings to the requirements of the system when installing the molded case circuit breakers. Changing the setting values for the overload and short-circuit releases during operation to a value below the present operating value causes instantaneous tripping. The protection parameters to be set on the electronic trip unit of the molded case circuit breaker depend on the technical environment (switchgear, cables), the network configuration, and the type of equipment to be protected. There are no fixed protection settings. The protection parameters can be determined by the relevant electrical planning engineer. The Siemens software tool SIMARIS Design offers a simple, quick and safe solution for dimensioning switching and protective devices. Internet link to SIMARIS (www.siemens.com/simaris) Tripping characteristic curve and settings parameters The time/current characteristic of a trip unit offers the best method for calculating the tripping characteristics of a trip unit. The tripping characteristic reflects the response of the circuit breaker in the event of a fault, e.g. overload or short-circuit. The time required to trip is defined at a specific current. The tripping characteristic is split into different sections. Each section reflects the tripping response of the circuit breaker at a specific current level Depending on the type of tripping, the trip units can be supplied with or without the S, N, or G functions (L, S, I, N, G designations in accordance with IEC 60947-2, Annex K). L long time delay = overload protection with current-dependent long time delay and current-dependent tripping curve (I2t = constant) S short time delay (short-circuit protection with short-time delay) = short-circuit protection with current-dependent or current-independent short time delay and current-dependent tripping curve (I2tsd = constant) I Instantaneous = short-circuit protection with instantaneous adjustable tripping. N Neutral protection = protection of the neutral conductor with adjustable, currentdependent tripping curve. G Ground fault = ground-fault protection with current-independent short-time delay 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 119 Parameter assignment / addressing 9.1 Setting the parameters Parameter L Setting buttons Effect on characteristic curve Brief description Cause IR Tripping current of the Setting to the operating current of overload protection IR = the circuit to be protected 0.4 to 1 x In tR Delay (or time-lag class) in the overload range.

Ground-fault protection is part of the fire protection. For LCD ETUs, the ST function must be set to the value "disabled" for tsd = 0. Setting of the protection parameter for line and generator protection The settings are variable depending on the trip unit (ETU10, ETU12, ETU20, ETU22, LCDETU40 and LCD-ETU42). The following parameters can be set depending on the version: L overload release IR: The overload release IR is set to the operating current IB of the circuit to be protected. This takes place with the help of the left rotary encoding switch IR that is set to the factor IB/In (example: IB = 250 A, In = 315 A => setting factor 250 / 315 = 0.79 corresponds to 0.8 on the rotary encoding switch). Delay time tr : The delay time (or time-lag class) tr can be set using another rotary encoding switch. The set time is the tripping time at 6 x Ir. In this way, selectivity to other molded case circuit breakers can be achieved in the overload range, for example, when the rated current range does not differ much. S short-time delayed short-circuit protection Isd : The short-time delay short-circuit protection can be set with regard to the tripping value of the current Isd and the delay time tsd. Isd refers to the tripping value of the overload release IR and can be set between 1.5 to 10 x IR (depending on the molded case circuit breaker). Delay time tsd : Depending on the requirements and on the trip unit, selectivity to the other molded case circuit breakers can be achieved with appropriate selection of the delay time tsd. If the rotary encoding switch is in the "ON" range, this means the delay time is current-dependent. The I2t value is constant. For example, the higher the current, the faster the circuit breaker will trip (equivalent to the overload release IR). In contrast, the delay time in the "OFF" position is current-independent, that is, constant. If the current reaches the set value Isd, the circuit breaker trips after the set time tsd. The degree to which the current exceeds the value Isd is not important. The set time is the tripping time at 8 x Ir. 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 121 Parameter assignment / addressing 9.1 Setting the parameters I2t waveform: A I2t waveform of the characteristic curve can be switched in (depending on the ETU), the delay time tsd is based on the reference point 8 x IR. Two different procedures are used to form the characteristic curve. As well as a fixed time delay for all currents in the characteristic curve section, the I2t characteristic can also be used. The tripping time falls continuously as the current increases, and the product of squared current and time remains constant. Figure 9-1 I2t I instantaneous short-circuit protection Ii: On some trip units, the instantaneous short-circuit release Ii can also be set. This refers to the rated current In of the molded case circuit breaker. It must always be noted that either the instantaneous short-circuit release (Ii) or the delayed short-circuit release (Isd) handles personnel protection. The tripping current of the short-circuit release of the molded case circuit breaker is set to a value that is at least 20% (tolerance of the trip unit) lower than the lowest short-circuit current at the installation location and simultaneously higher than the maximum operating current +20%. This guarantees that the circuit breaker will trip within the required time even with the smallest short-circuit current, and that correct currents will not result in unwanted trips. G ground-fault protection Ig: The tripping value of the of the ground-fault release Ig is fixed to the rated breaker current on the ETU12 and ETU22. The tripping current of the ground-fault release can be set to between 0.6 and 1 x In, and the delay time tg can be set between 0.3 s and 0.6 s. The measuring methods for the ground-fault protection are specified on the representation of the trip unit. On the ETU42, the tripping current of the ground-fault release can be set to between 0.4 and 1 x In, and the delay time can be set between 0.1 s and 0.5 s. Note Ground-fault protection It must be noted that the ground-fault protection is not a residual-current operated circuit breaker (FI or RCD in the building installation). Fault currents to ground therefore cannot be detected, only ground "short"-circuits. 3VL IEC molded case circuit breakers 122 System Manual, 11/2013, 110 0110 - 02 DS 03 Parameter assignment / addressing 9.2 Setting the protection parameters for motor protection (ETU10M, ETU30M and LCD-ETU 40M) 9.2 Setting the protection parameters for motor protection (ETU10M, ETU30M and LCD-ETU 40M) The selection of the molded case circuit breaker is oriented around the rated operating current of the motor; the releases are specially designed for overload protection of 3-phase motors. Overload release IR: The overload release IR is set to the rated current of the motor, in the same way as protection parameters for line and generator protection. The overload protection is finely adjustable with the left rotary encoding switch (first decimal place) and the center rotary encoding switch (second decimal place) in the range between IR = 0.41; 0.42 to 0.98; 0.99; 1 x In (In = rated breaker current). Example Adjusting to the motor current 360 A is carried out for the rotary encoding switch left and center (ETU10M and ETU30M) (rated breaker current In = 500 A) as follows: Overload protection setting Setting IR / rated breaker current In = 360 A / 500 A = 0.72 1. Setting the rotary encoding switch left factor 0.7 2. Setting the rotary encoding switch center factor 0.02 Short-circuit release Ii Furthermore, instantaneous short-circuit release Ii can also be set depending on the trip unit. This setting value refers to the rated current In of the molded case circuit breaker. As with line and generator protection, the minimum short-circuit must be taken into account when selecting the setting. With the ETU30M version, you must note that the setting of the short-circuit release is selected in combination with the time-lag class. The rotary encoding switch is divided into three areas here, corresponding to the values 6, 8 or 11 x In. The desired time-lag class can be selected within these ranges. 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 123 Parameter assignment / addressing 9.2 Setting the protection parameters for motor protection (ETU10M, ETU30M and LCD-ETU 40M) Setting the time-lag class/trip class The 3VL molded case circuit breaker offers the option of selecting from various time-lag classes or trip classes for different motor applications. One version (ETU10M) contains a thermal image and phase failure sensitivity based on a fixed trip class 10. With the ETU30M, both the time-lag class TC and the tripping current of the short-circuit release are set in combination with the right rotary encoding switch. The other version (ETU40M) with an LCD trip unit permits step by step setting from class 5 to 30. The setting in accordance with CLASS 5 is only used on motors with an extremely low overload capacity. In CLASS 30, by contrast, the motor must be suitable for starting under a heavy load. That is, the trip class must be adapted to the start-up time of the motor. Definition of the trip class The trip class specifies the start-up times during the motor start in accordance with IEC 60947-4-1. The trip class is defined by the tripping time at 7.2-times the set current level (in the cold state). Combinations with CLASS 10 are generally used. The tripping times are as follows: CLASS 5 between 0.5 and 5 secs, CLASS 10 between 4 and 10 secs, CLASS 20 between 6 and 20 secs, CLASS 30 between 9 and 30 secs. Applications such as fans, require longer start-up times. Phase failure sensitivity The "phase failure sensitivity" function is also integrated into the trip units for motor protection ETU10M, ETU30M and ETU40M. This ensures that the motor is reliably protected against overheating if a phase interruption or a large fluctuation occurs. The phase failure sensitivity protects 3-phase AC motors against overheating while only 2 phases are active. The specified operating current IR is automatically reduced to 80% of the set value if the RMS values of the operating currents in the three phases in the case of the ETU10M and ETU30M trip units differ by more than 40%. If an adjustable phase unbalance of 5 to 50% is set on the ETU40M trip unit, the set operating current IR is automatically reduced to 87% of the set value. Thermal image All releases with overload protection function have a "thermal image" which takes the preloading of the AC motor into consideration. The function of the fixed thermal image cannot be switched off (except on the ETU40M). Following an overload trip of the molded case circuit breaker, the tripping time is reduced by the thermal pre-loading of the molded case circuit breaker in such a way that further overloads cannot harm the motor windings. After an overload trip, the tripping times are reduced in accordance with the tripping characteristic curves so that the inrush current can already cause a trip. A cooling time dependent on the size of the motor is required before the motor can be switched on again. 3VL IEC molded case circuit breakers 124 System Manual, 11/2013, 110 0110 - 02 DS 03 Service and maintenance 10.1 10 Preventive measures Maintenance DANGER Qualified personnel Functionality tests and maintenance tasks must only be carried out by qualified personnel due to the dangers associated with electrical equipment. The following inspection intervals must be defined by the operator (qualified skilled personnel) depending on the conditions of use of the relevant 3VL molded case circuit breaker: At least 1 x per year After severe high-energy shutdowns After trips caused by the electronic overcurrent release After shutdowns caused by the thermal overcurrent release After shutdowns caused by the magnetic instantaneous overcurrent release Additional testing of downstream molded case circuit breakers. 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 125 Service and maintenance 10.1 Preventive measures Inspection The following checks must be carried out within the scope of the inspection(s) and/or after 1,000 rated current shutdowns. Please proceed as follows: External circuit breaker housing - Examine all visible surfaces for oxidation, residues or other adverse effects. - Remove residues with a lint-free, dry and clean cloth. (Never use chemical cleaners or water) NOTICE Damage to the molded case circuit breaker Never carry out repairs to the plastic casing or the interior of the circuit breaker! Molded case circuit breakers contain only maintenance-free components. Electrical and mechanical functions of the circuit breaker - Test the operating lever to check the mechanical functioning of the molded case circuit breaker contacts Function of the mechanical on and off switch - Operate the trip button, if available. Return the molded case circuit breaker to the starting position after each operation. Main circuits and control circuits, function. Check connections are tight - Check the tightening torque of the connecting screws (80% of the tightening torque recommended) - Visual inspection of the incoming and outgoing cables - Visual inspection of the connection accessories - Replace damaged terminal accessories after cleaning the terminal area Check and, if necessary, correct the settings of the overcurrent release in accordance with the system conditions - Electronic molded case circuit breaker releases must only be tested with a device especially supplied for this purpose (MLFB: 3VL9000-8AP01). The operator (customer) must arrange for the disposal of the molded case circuit breaker or the replaced parts at the end of their service life in accordance with the currently applicable legal requirements and guidelines. 3VL IEC molded case circuit breakers 126 System Manual, 11/2013, 110 0110 - 02 DS 03 Service and maintenance 10.2 Troubleshooting 10.2 Troubleshooting Notes on troubleshooting Table 10- 1 Troubleshooting Circuit breaker status Overload causes circuit breaker to trip: Causes of faults Excessive current Corrective action The circuit breaker is functioning correctly and switches off an overload that occurs. Check to see if the operating current has exceeded the thermal tripping limit. Connecting cable not Carry out a visual inspection of the terminals for discoloration. Cables correctly connected to the can become loose during service due to various reasons such as circuit breaker vibration (machine tool applications) and cold flow (for aluminum cables) Ambient temperature too high This can be a problem on hot summer days or in areas subject to extreme heat. Although all 3VL molded case circuit breakers are calibrated for use at an ambient temperature of 50 C, the temperatures in the enclosures can exceed this level. It may be necessary to consider derating the In or IR values. See the Chapters Use in unusual environments, and Derating factors Overcurrent release not If none of the above suggestions apply, the overcurrent release must correctly connected to the be removed from the molded case circuit breaker and inspected for circuit breaker. discoloration. The tightening torque values are listed in the operating manual supplied with every circuit breaker. Short-circuit causes circuit breaker to trip: Excessive making current, e.g. motor Adjust the magnetic trip rating to the next highest setting or until the circuit breaker does not trip when the motor is started. High current peaks, e.g. when changing from star to delta in star-delta starters. A current peak of up to 20 times the rated current of the motor can occur when changing from star to delta. In this case, the short-circuit release "I" must be set to a higher value. However, this may result in the loss of the desired higher motor protection function. 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 127 Service and maintenance 10.2 Troubleshooting Circuit breaker status Mechanical and electrical functions: Causes of faults Corrective action High humidity The molded case circuit breakers must not be used in environments with high humidity since this can cause dielectric and insulation problems. In such environments, appropriate measures need to be taken, such as placing the circuit breaker in an enclosure. Corrosion The molded case circuit breakers are not designed to be used in aggressive environments. In such environments, the circuit breaker should be installed in a housing. Function of the internal accessories Determine what type of internal accessories are installed. Remove the molded case circuit breaker cover and determine the type of accessories using the circuit breaker order number. Then check for correct functioning. * Undervoltage release: Ensure the correct voltage is connected to the undervoltage release since otherwise, the circuit breaker cannot be tripped. * Shunt release: Ensure the voltage is not applied to the shunt release since this can also prevent the circuit breaker from tripping. * Auxiliary and alarm switches: The auxiliary and alarm switches do not have any effect on the protection function of the molded case circuit breaker. 3VL IEC molded case circuit breakers 128 System Manual, 11/2013, 110 0110 - 02 DS 03 11 Technical data 11.1 General data - 3VL molded case circuit breakers Type VL160X 3VL1 VL160 3VL2 VL250 3VL3 VL400 3VL4 VL630 3VL5 VL800 3VL6 VL1250 3VL7 VL1600 3VL8 Max. rated current In [A] 160 160 250 400 630 800 1250 1600 N pole [A] 160 160 250 400 630 800 1250 1600 Rated insulation voltage Ui in accordance with IEC 60947-2 Main current paths [V AC] 800 800 800 800 800 800 800 800 Auxiliary circuits [V AC] 690 690 690 690 690 690 690 690 Rated impulse withstand voltage Uimp Main current paths [kV] 8 8 8 8 8 8 8 8 Auxiliary circuits [kV] 4 4 4 4 4 4 4 4 IEC 50 / 60 Hz [V AC] 690 4) 690 690 690 690 690 690 690 IEC DC3) 500 600 600 600 600 -1) -1) -1) NEMA 60 Hz [V AC] 600 600 600 600 600 600 600 600 Utilization category (IEC 60947-2) A A A A A A A A Rated operating voltage Ue Permissible ambient temperature Operation [C] 2) Storage [C] 0 to +70 -25 to +70 -25 to +70 -25 to +70 -25 to +70 -25 to +70 -25 to +70 -25 to +70 -40 to +80 -40 to +80 -40 to +80 -40 to +80 -40 to +80 -40 to +80 -40 to +80 -40 to +80 1) Breaker cannot be used for direct current. 2) Exception: 3VL molded case circuit breaker with TMTU: 0 C ... 70 C 3) The values apply for at least 3 current paths in series and extremely high breaking capacity L.

No-load operations represent a high level of stress for the molded case circuit breaker. If the undervoltage release is without power, auxiliary contactor K1 has not picked up. The contact in the ON circuit (control circuit) of the motorized operating mechanism is thus not closed, that is, the molded case circuit breaker cannot be switched. This auxiliary contactor is not necessary in principle when the undervoltage release is supplied uninterrupted (e.g. pushbutton S01) from the same source as the motorized operating mechanism itself (e.g. contact 1).

The contact of auxiliary contactor K1 or K3 prevents no-load operation of the molded case circuit breaker when the undervoltage release "U<" is without power. No-load operations represent a high level of stress for the molded case circuit breaker. If the undervoltage release is without power, auxiliary contactor K1 or K3 has not picked up. The contact in the ON circuit (control circuit) of the motorized operating mechanism is thus not closed, that is, the molded case circuit breaker cannot be switched. This auxiliary contactor is not necessary in principle when the undervoltage release is supplied uninterrupted (e.g. pushbutton S01) from the same source as the motorized operating mechanism itself (e.g. contact 4). 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 299 Circuit diagrams Circuit diagrams, undervoltage release and shunt release "S contat" integrated into shunt release Undervoltage release and shunt release for VL160X to VL1600 S01 Delayed release S02 Instantaneous release for EMERGENCY-OFF loop (if required) S03 Leading auxiliary contact, e.g. 3VL9300-3AS10 "OFF to ON" in the front-operated rotary operating mechanism of the molded case circuit breaker (if required) K1 Auxiliary contactor 3RH11 (if required) Figure 13-7 Time-delay device (3TX4701-0A) for undervoltage release for VL160X to VL1600 Protective circuit with UVR (220 V to 250 V DC) Tripping time UVR Y2 only Approx. 3 seconds Y2 and Y1 bridged Approx. 6 seconds Protective circuit with UVR and contactor Tripping time UVR Drop-out time contactor Y2 only 0.8 s Approx. 2 s Y2 and Y1 bridged 1.2 s Approx. 4 s 3VL IEC molded case circuit breakers 300 System Manual, 11/2013, 110 0110 - 02 DS 03 Circuit diagrams Circuit diagrams 3VL plus RCD module Q0 Molded case circuit breakers A Evaluation electronics F0 Closing solenoid with local trip indication and reset TEST Test button Figure 13-8 4-pole 3VL1 with RCD module (3-pole version corresponds, but without N pole) 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 301 Circuit diagrams Q0 Molded case circuit breakers A Evaluation electronics F0 Closing solenoid with local trip indication and reset TEST Test button S0 Remote trip (to be provided by customer) Figure 13-9 4-pole molded case circuit breaker for 3VL2, 3VL3 and 3VL4 molded case circuit breakers with remote trip unit and RCD alarm switch (3-pole version corresponds, but without N pole) 3VL IEC molded case circuit breakers 302 System Manual, 11/2013, 110 0110 - 02 DS 03 Spare parts/accessories 14.1 14 Installation The following safety accessory parts are available for installing in the 3VL molded case circuit breaker: Masking frames for door cutouts Terminal covers / phase barriers Phase barriers Toggle lever extension 3VL IEC molded case circuit breakers System Manual, 11/2013, 110 0110 - 02 DS 03 303 Spare parts/accessories 14.1 Installation Masking frames for door cutouts: Masking frames for door cutouts are used to increase the IP degree of protection of the molded case circuit breakers and to better adapt them to the control cabinets.
