Abstract
A switching device has an input terminal and an output terminal for connection to electrical conductors, and two switching contacts which, when closed, close a current path between the input terminal and the output terminal. A disconnect device for disconnecting the two switching contacts is operatively connected to a short-circuit trigger device which is arranged in the region of the input terminal and triggers the disconnect device. The short-circuit trigger device includes a U-shaped yoke and a movable hinged armature, which simplifies the design.
Claims19
A switching device, comprising:
- an input terminal and an output terminal for connection to electrical conductors;
- first and second switching contacts which, when closed, close a current path between the input terminal and the output terminal;
- a disconnect device operable to disconnect the first switching contact and the second switching contact;
- and
- a short-circuit trigger device comprising a U-shaped yoke and a movable hinged armature, said short-circuit trigger device arranged in a region of the at least one input terminal and mechanically operatively connected with the disconnect device for triggering the disconnect device.
