Abstract
The invention relates to an electrical switching device, having a thermal release, an electromagnetic release, and a switching mechanism with a latching point. A contact base for moving a contact member is located between the thermal release and the electromagnetic release. The thermal release is coupled to a release lever by means of a connecting rod passing over the contact base so that both the thermal release and the electromagnetic release open the latching point in the event of an overcurrent and/or short-circuit current.
