Page 23: Thermal-Magnetic Overcurrent Trip Units
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.
Page 24: Electronic Overcurrent Trip Unit (Etu)
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.
Page 25 Product description 3.3 Configuration In the case of an LCD display, the electronic trip unit must be activated. This requires a 3- phase (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.

Page 35: Functions
Functions Protection functions 4.1.1 Overcurrent release 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 I as well as the mechanical load resulting from the impulse short-circuit current I of the system components that occur during a short-circuit.

Page 44: Differential Current Protection With Rcd Module
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.
Page 45 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.
Page 46 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 47 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.

Functions 4.1 Protection functions 4.1.6 Single-pole operation with RCD module Connection of the RCD module for single-pole operation All 3-pole or 4-pole molded case circuit breakers with RCD module can be operated with 2 poles (L to N), since the power supply of the RCD module is supplied from all three external conductors, and on 4-pole devices additionally from the N conductor.

Page 50 Functions 4.1 Protection functions Ground fault detection in unbalanced systems The neutral conductor current is measured directly. 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.

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.
Page 54: Auxiliary Switches And Alarm Switches
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 short- circuit or overcurrent, or when the shunt release, undervoltage release, test button, or RCD module trips.
Page 55 Functions 4.2 Internal accessories Application example: If the molded case 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 58: Use Of Capacitor Banks
Application planning 5.2 Use of capacitor banks Use of capacitor banks Capacitor banks are used, for example, for reactive power compensation. 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.

Application planning 5.3 Transformer protection on the primary side 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.

Page 63 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. If this fault occurs, the entire phase-to-phase voltage is applied via one pole of the molded case circuit breaker.
Page 64: Use In Motor Protection
Application planning 5.6 Use in motor protection Use in 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 are sensitive for phase failures and have an adjustable trip class. The ETUs operate with a microprocessor.
Page 65 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).
