ABSTRACT:
A contact arrangement of a low-voltage circuit breakeer with electrodynamic breaking or opening. In contact arrangements which contain a compression spring for pretensioning a contact lever into the make position or after a dead center position is passed, the assembly is to be simplified and the use of an assembly fixture is to be made unnecessary. The pivot bearing of a contact lever at a contact lever carrier is formed by a pan-like depression of the contact lever carrier as well as an extension of the contact lever engaging the depression. Furthermore, a stop surface for the open position of the contact lever is arranged at the contact lever carrier. A brief application of force is sufficient for connecting the contact lever to the contact lever carrier. A current-limiting low-voltage circuit breaker of compact design is thus provided.
