Electric installation switching device

摘要

The device has a magnetic actuator with an armature, a thermal actuator, a fixed contact piece and a movable contact piece, a latch for releasing the actuators. A contact lever forms a switchable assembly, which is fabricated in housing of an installation device, swivellably stored at a fixed rotary axis after insertion into the housing. A switch knob forms another assembly, which is fabricated in the housing, with a bracket, a release lever (40), a ratchet lever (37) and an intermediate lever (33). The latter assembly is connected with a component after insertion at a disconnecting point.
