Abstract (en)
[origin: EP0231732A2] 1. Fault-current and line protection circuit breaker with a switch for a neutral conductor, in which the movable switching bridge of the line protection circuit breaker located in one housing part is connected to the movable contact arm of the switch for the neutral conductor received in a further housing part, by way of a slide (7) guided on an intermediate wall of the housing, characterised in that associated with the permanent magnet tripping device (2) of the fault current circuit breaker is a lever (8) mounted to tilt in the housing, the tripping pin (9) of the permanent magnet tripping device (2) bearing against one end (11) of the lever (8) and, in the "on" position of the switch, the other end (12) of the lever (8) being locked to a spring-loaded (17) actuating member (14), which comprises a pin (18) associated with the spring rest of the line protection circuit breaker and that provided on the slide (7) is a pin (19), which tilts the actuating member (14) against the force of the spring (17) associated therewith when the contact arm (6) of the switch for the neutral conductor in its closed position is tilted into the correct position for locking to the lever (8) associated with the permanent magnet tripping device (2).
