摘要:
An electrical switching device is disclosed which can be used in combination with a line, motor or fault-current circuit breaker, with a thermal release, with an electromagnetic release, with a switching mechanism with a latching point and at least one contact point which is continuously opened or closed by the switching mechanism, with an operating handle which is connected to one end of a lug by a coupling element and the other end of which is coupled to a contact base carrying the moving contact member, and with a latching lever which, together with a release lever, forms the latching point. The contact base for the moving contact member is located between the thermal release and the electromagnetic release. Together with a rotatably supported release lever interacting with the electromagnetic release and the thermal release, the latching lever forms the latching point. The thermal release is coupled to the release lever by 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 and in that a striking lever is provided, which is mounted such that it can rotate, can be pivoted on the one hand by the thermal release and on the other hand by the electrical release, and, on release, pivots the release lever in the direction to unlatch the latching point.
