Abstract
A circuit breaker comprises base angles to which sliding rails are connected. To the sliding rails are fastened coupling claws which have recesses for extending over coupling pins of a positioning drive. By posts of the coupling claws provision is made in conjunction with locking pieces attached to the rolling floor that the circuit breaker can be detached from the positioning drive only in its disconnected position.
