The transition auxillary contactor operably controls the operation of a shorting contactor, and the shorting auxillary operatively controls the operation of the run contactor.
The invention relates to a circuit-breaker which is activated by rotation and which has a leading auxiliary switch.
The invention concerns an electrical switch, for instance a contactor, protective circuit breaker or relay, with a locking-screw securing device.
When the circuit-breaker is switched on, the auxiliary contacts of the auxiliary switch (4) are activated temporally before the main contacts.
Said first gear rack (21) engages with the drive pinion (20) and activates the auxiliary switch (4).
The invention provides for an actuator element (6) containing a driving pinion (20) which is rotation-activated by an actuating mechanism (8) and a first gear rack (21) which is arranged in such a way that it can be moved longitudinally.
The transition auxillary contactor operably controls the operation of a shorting contactor, and the shorting auxillary operatively controls the operation of the run contactor.
The modular contactor includes a mounting base to which both a contactor module and an auxiliary function module are releasably mounted.
The invention relates to a circuit-breaker which is activated by rotation and which has a leading auxiliary switch.
The invention relates to an electromagnetic switching device (1), in particular a contactor, having an auxiliary switch (2).
The invention concerns an electrical switch, for instance a contactor, protective circuit breaker or relay, with a locking-screw securing device.
The invention relates to an electromagnetic switchgear (1), especially a contactor, comprising an auxiliary switch (2).
When the circuit-breaker is switched on, the auxiliary contacts of the auxiliary switch (4) are activated temporally before the main contacts.
The high voltage contactor opens the normally closed high voltage auxiliary contact to disconnect the low voltage coil.
A port of the accumulator apparatus is connected to the power output end and to the auxiliary system via the contactor.
