Auxiliary switching device for an electrical disconnect device and an electrical switching apparatus

Auxiliary switching device for an electrical disconnect device, wherein the electrical switching apparatus, when a low voltage and / or current pulses at the rear of the circuit interrupting current, which has a spring element, and can be tensioned in a position that has been memory element movable between a relaxed position, and for disconnecting the disconnect element electrically activated elements of the switching device disconnecting mechanism, wherein the memory element is configured to position of the tension has been activated by the element when activated the mechanical energy storage element output to OFF. In particular said auxiliary opening device is characterized in that a blocking element movably supported, the latching member has been so connected to the memory element acting position of the tension in the storage element in a first position, i.e., a storage element supported by the blocking element; and the locking element releases the storage element is in the second position, for performing an exercise.
