Abstract

A circuit breaker includes a switching contact arrangement and a drive apparatus which operates it, with the connection between the switching contact arrangement and the drive apparatus being designed such that it is detachable. For this purpose, a contact support of the switching contact arrangement contains a coupling bolt, which produces a hinged connection to a lever arrangement for the drive apparatus. A holding piece allows a actuating shaft of the drive apparatus to be rotated to a position, and to be fixed in this position. This allows the switching contact arrangement to be removed without any problem, and subsequently to be replaced by another switching contact arrangement. Once the control panel for the circuit breaker has been removed, the holding piece can be placed on the actuating shaft and can be attached to a front housing body of the circuit breaker where the control panel would otherwise be located.
