Abstract (en)

[origin: EP0620580A1] Auxiliary trip device (1) for a circuit breaker, comprising: a coil (10) surrounding a sheath (18), in the sheath, a fixed core (22), a movable core (24), a pusher (28) linked to the movable core and a first spring (30) continuously pressing the pusher in the direction of increasing the dimensions of an air gap; and an energy-accumulation system including a blade (4), a second spring (8) and a latch (55) hooked to the blade and movable in order to liberate it by unhooking. According to the invention, the said second spring (8) is stronger than the said first spring (30) and an actuating part (32) of the pusher (28) pushes on an actuating part (62) of the latch (55), a clearance being provided between the said actuating part (32) of the pusher and the said actuating part (62) of the latch when the pusher is not displaced. <IMAGE>
