Page 19: Configuration
Product description 3.3 Configuration Configuration 3.3.1 Functional principle Design - mechanical principle All SENTRON VL 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.
Page 20: Thermomagnetic Overcurrent Trip Units
However, the VL800 to VL1600 circuit breakers are only available in the version with electronic overcurrent trip unit. As with all electronic overcurrent trip units for the SENTRON VL circuit breakers from Siemens, the current transformers (one per phase) are accommodated within the overcurrent trip unit housing. They transmit a signal proportional to the load current to the electronic trip unit.
Page 21: Electronic Overcurrent Trip Unit (Etu)
● Evaluation electronics with microprocessor ● Tripping solenoid In all versions with electronic trip units for the SENTRON 3VL circuit breakers, the current transformers are located in the same housing as the trip unit. At the output of the electronic overcurrent tripping module, there is a tripping solenoid that releases the circuit breaker in the event of an overload or short-circuit.
Page 22 Product description 3.3 Configuration Power supply The protection functions of the electronic overcurrent trip unit are guaranteed without additional auxiliary voltage. The overcurrent trip units are supplied with energy via internal current transformers. The protection function is parameterized via rotary encoding switches on the ETU or via an LCD display.

Page 41: Functions
Functions Current protection 5.1.1 Overcurrent trip unit The SENTRON VL 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 significantly reduces the thermal load I t as well as the mechanical load resulting from the impulse short-circuit current IP of the system components that occur during a short-circuit.

Page 51: Differential Current Protection With Rcd Module
Functions 5.1 Current protection 5.1.6 Differential current protection with RCD module The circuit breakers with differential current protection are used in a variety of ways 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 supplied as accessories for the VL160X, VL160, VL250 and VL400 circuit breakers with thermomagnetic overcurrent trip units.
Page 52 Functions 5.1 Current protection Standard features ● Mechanical trip display: The Reset button pops out when the RCD module trips the circuit breaker. ● Reset button: This must be manually reset after the circuit breaker has been tripped by the RCD module. The circuit breaker can only be reset and switched on again after the RCD module has been reset.
Page 53 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).
Page 54 Functions 5.1 Current protection Special requirements ● Every RCD module requires a separate cable for remote tripping. It is not possible to use one cable when switching 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.

Page 63: Auxiliary Switches And Alarm Switches
Functions 5.2 Voltage protection 5.2.3 Auxiliary switches and alarm switches Auxiliary and alarm switches are used to indicate the switching status of the circuit breaker. Auxiliary switches show the position of the main contacts ("ON" or "OFF"). Alarm switches transmit a signal when the circuit breaker trips due to a short-circuit or overcurrent, or when the shunt release, undervoltage release, test button, or RCD module trips.
Page 64 Functions 5.2 Voltage protection Leading auxililary switch for switching from "OFF" to "ON" (leading NO contact) Application example: If the circuit breaker is equipped with an undervoltage release, and the leading auxiliary switch is installed in the rotary operating mechanism, the leading NO contacts make it possible to supply the undervoltage release with power before the main contacts can be closed.
Page 65: Application Planning
Application planning Use with frequency converters Frequency converter and SENTRON VL circuit breaker combination SENTRON VL circuit breakers can be used as primary connection protection devices in systems in which frequency converters, variable-speed drives, and electronic motor control devices are used.

Page 67: Use Of Capacitor Banks
Application planning 6.2 Use of capacitor banks Use of capacitor banks In general, reactive power compensation is used in order to reduce system losses and voltage drops in the power distribution system. As a result, the power fed into the system is used as active power and costs will be saved through a reduction in the capacitive and inductive power factors.
Page 68: Primary-Side Transformer Protection
Application planning 6.3 Primary-side transformer protection Primary-side transformer protection The circuit breaker as primary-side transformer protection 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 circuit breakers if these are also used to switch the transformer.

690 V AC. The switching capacities can be found in the certificates of conformance testing (Page 346). The 3VL8 cannot be used in the IT network. The SIEMENS SENTRON VL circuit breakers for system protection, optionally with thermal overload and electromagnetic short-circuit releases, or electronic overcurrent trip units, are suitable for use in IT networks.
Page 72 Application planning 6.5 Use in IT networks Fault situation The most critical fault for circuit breakers in ungrounded IT networks is a double ground fault on the incoming or load side of the circuit breaker. If this fault occurs, the entire phase-to- phase voltage is applied via one pole of the circuit breaker.

Page 74: Use In The Motor Protection Area
Application planning 6.6 Use in the motor protection area Use in the motor protection area The overload and short-circuit releases are designed for optimal protection and direct- starting three-phase AC squirrel-cage motors. The motor protection circuit breakers are sensitive for phase failures and have an adjustable trip class. The overcurrent trip units operate with a microprocessor.
Page 75 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 SENTRON VL circuit breakers with fixed thermal memory to provide maximum protection for motors. Functional principle of the thermal memory During operation, a thermal image of the motor is simulated in the ETU.
Page 76 Application planning 6.6 Use in the motor protection area Phase failure sensitivity The "phase failure sensitivity" function is also integrated into the SENTRON VL circuit breakers 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 r.m.s.
