A switchgear unit switches high DC voltages, particularly for interrupting of direct current between a direct current source and an electrical device. The switchgear unit contains two connections which project from a housing and which are electrically conductively coupled by a conductor path, a contact system which is arranged between the first and second connections and an isolating apparatus that can be tripped by a thermal fuse. The thermal fuse contains a melting location which is arranged in the conductor path and which is connected first to the contact system and second via a moving conductor section to the first connection. The isolating apparatus is tripped and the connection between the conductor section and the contact system is broken at the melting location when an arc produced when the contact system is opened has caused the melting temperature of the melting location to be reached or exceeded.

A miniature circuit breaker has a housing, comprising a housing base consisting of insulating material, and a pot-like housing cover, which is or can be positioned onto the housing base. Two elongate and flat contact arms are partially embedded in the housing base parallel with respect to one another in terms of their longitudinal direction. A fixed contact is arranged at an inner end of a first one of the contact arms. A bimetallic snap-action disk with a free end, forming or bearing a moving contact, is fitted at an inner end of the second contact arm at a fastening point. The fastening point, the moving contact and the fixed contact are in this case on an axis which is parallel to the longitudinal direction of the contact arms.
