Patent abstract
An electrical switchgear includes a thermal trip, an electromagnetic trip, and a switching mechanism with a latching point and at least one contact point that is continuously opened or closed. An operating handle is connected to one end of a lug by means of a coupling element and the other end of the lug is coupled to a contact base that carries a moving contact member. The thermal trip is coupled to a trip lever by a connecting rod that passes over the contact base so that both the thermal trip and the electromagnetic trip open a latching point in the event of an excess current and/or short circuit current.
