Multi-polar switching device for reversing protective circuit of three phase electric motor, comprising main housing and auxiliary housing, and switching device is locked mechanically at opposite side with another switching device

摘要

The device (1) has a main housing (2) and an auxiliary housing (3), in which a rotating contact is arranged with the contacts for a pole and an inter-linkable actuating mechanism (9). The switching device is locked mechanically at the opposite side with another switching device that is configured laterally at the auxiliary housing over an actuating mechanism in auxiliary housing. An independent claim is also included for the auxiliary housing for the multi-polar switch device.
