- Page 19 Description Motor (-M1) After the supply voltage is applied and if the closing spring is discharged, the motor starts immediately and is automatically deactivated internally after charging has taken place. For power consumption see table Fig. 20. In the short charging time, the motor operates in the overload range.
- Page 20 Description Auxiliary contactor (-K1) If simultaneous electrical CLOSE and OPEN commands are continuously applied to the vacuum circuit-breaker, it returns to the open position after being closed. The function of the auxiliary contactor (-K1) causes the vacuum circuit-breaker to pause at this point until the CLOSE command is given again.
- Page 21 Description First shunt release (-Y1) In the case of the first shunt release (-Y1), the electrical- ly fed tripping pulse is passed to the "OPEN" latch by means of a directly acting magnet armature, thus open- ing the vacuum circuit-breaker. The first shunt release (-Y1) is not designed for continu- ous operation and is terminated within the circuit-breaker via the auxiliary switch (-S1) at the factory.
- Page 22 Description Auxiliary switch (-S1) Auxiliary switch (-S1) is available for delivery in two ver- sions: With 6 normally open contacts or 12 normally closed contacts each. Contacts available on the custom- er's premises - see circuit diagram supplied. Fig. 26 Auxiliary switch (31) Power consumption Rated insulation voltage:...
- Page 23 Description Circuit-breaker tripping signal (-S6) 3AX4206-0A The position switch (-S6) makes contact briefly when the vacuum circuit-breaker is opened by means of an elec- trical release. This contact can be used for a signal. Fig. 27 Circuit-breaker tripping signal (54.6) A further shunt release, current transformer-operated release or undervoltage re- lease can be installed as a second or third release.

If the tripping current is exceeded (90 % of the transformer-operated release's rated current), the stored energy mech- anism is unlatched, thus initiating opening of the vacuum circuit-breaker.
- Page 25 Description Undervoltage release (-Y7) 3AX1103 Note The undervoltage release (-Y7) may only be operated with the supplied series re- sistor (-R1). Note For circuits (mechanical or electrical), the undervoltage release 3AX1103… must be connected to control voltage, as otherwise a switch-on is not possible (see “Removing the transport block from the undervoltage release”, page 48).
- Page 26 Description Heater (-R01) for condensation water protection (optional) The heater limits condensation and corrosion of the vac- uum circuit-breaker.
