Abstract (en)

[origin: EP3451360A1] A movable contact operating mechanism of leakage circuit breaker, comprising a movable contact (6), a bounce buckle (1), a movable contact support (2), a locking spring (3), a locking buckle (4) and a tension spring (5); a long through hole (21) is provided on the movable contact support, a pin shaft (7) is provided in the long through hole, two ends of the pin shaft are arranged on a base and a cover of the leakage circuit breaker; the bounce buckle is hinged on an upper end of the movable contact support, a central part of the locking buckle movably sheathes the pin shaft by means of a provided through hole (41), a contact pin (42) is provided extendingly above the locking buckle, and the contact pin is abutedly engagable with the bounce buckle to limit the rotation of the bounce buckle; a driving pin (43) and a resetting pin (44) are provided below the locking buckle; by means of the present operating mechanism, a movable contact operating mechanism of leakage circuit breaker may be provided, which allows the length or width of the leakage circuit breaker to be smaller than that of a product of existing technologies, and therefore better suited to meet a client's requirements.
