ABSTRACT:
A mechanical locking device for mechanically connected contactors includes a first and a second actuating member and a locking element. The actuating members are operatively connected respectively to an electromagnetic operating mechanism and a movable contact of a respective contactor. The first actuating member has a first curved recess adjacent the first connecting sidewall. The second actuating member has a second curved recess adjacent the second connecting sidewall. The locking element includes a rolling element received in a respective opening in each of the first and second connecting sidewalls. The first actuating member urges the locking element into the second recess when the first contactor is in a switched-on condition and the second actuating member urges the locking element into the first recess when the second contactor is in a switched-on condition.
