<p>Circuit breaker comprising, in particular, on the one hand, a coupling mechanism (32, 74) which, in order to control a moving contact, is set up between the said moving contact and a locking and unlocking handle (37), and is formed of two coupling members (32, 74) able to disengageably interlock, and on the other hand, a sensitive relay (122) which, in response to a possible differential current, is able to act, by way of a transmission (123), on the said coupling mechanism (32, 74) in order to break the latter. The transmission (123), being a direct transmission, comprises a part (130) which forms, all in one piece, a rotatably mounted column (131) and at least two arms, namely a control arm (128) for actuating the sensitive relay (122), and an actuating arm (129) for acting, by way of a pin (140), on the vane (51) carrying the coupling member (74). Application to circuit breakers. <IMAGE></p> |
