Abstract (en)
[origin: EP0331586A1] An auxiliary tripping block for a modular circuit-breaker comprises a tripping relay (18) and a plate (24), with catch (22), associated with an energy-storing spring (60). The plate (24) carries a lug (20) for transmitting the tripping order to the switching mechanism of the circuit-breaker, and an articulation spindle (28) for a tripping lever, this comprising a first arm interacting with the catch (32), and a second arm separated from the relay (18) by a resetting lever (44) mounted in free rotation on a spindle (46). The relay (18) serves to unlock the catch (32) so as to release the plate (24) which, under the relaxation of the spring (60), transmits the tripping force to the circuit-breaker and ensures the automatic resetting of the relay (18) by way of the resetting lever (44). The relay (18) of the actuating mechanism (12) of the auxiliary block requires a reduced tripping force. Applications: differential trip, with transmission MX and under-voltage MN. <IMAGE>
