Abstract

1. Fault-current or line protection circuit breaker (1) with a circuit breaker (12) for a middle conductor, in which the movable connecting bridge (4) of the circuit breaker is connected to the movable contact (14) of the circuit breaker (12) for the middle conductor by way of a slide (22) guided on the side wall of the housing (2, 3) of the circuit breaker, in which case the slide (22) comprises a lug (25) engaging on the connecting bridge (4) of the circuit breaker and at least one projection (26) located on the opposite side of the slide (22) to the lug (25) and engaging on the movable contact (14) of the circuit breaker (12) for the middle conductor and in which case the lug (25) is insulated electrically with respect to the projection (26), characterised in that the lug (25) constructed as a pin is the bearing bolt for the joint between the connecting bridge (4) and its actuating member, namely a bridge cover plate (5) and that the projection (26) engaging on the movable contact (14) of the circuit breaker (12) for the middle conductor is a pin engaging in a hole in the movable contact (14).
