Abstract (en)
[origin: EP0037295A1] 1. High-speed circuit-breaker comprising a contact (10) opening operating device having a Thomson effect driving member (14, 16) for quickly moving the movable part in opening direction and a latch device (20) of the movable part in open position, having an unlatch actuating device (24, 26) with a conductive unlatch disc (24) disposed in the rest position in face and at small distance from the front face of an unlatch winding (26) so that the disc is repulsed into the unlatch position when the unlatch winding is powered, characterized in that it further comprises a shock-proof device (32, 34, 38) comprising a draw-back spring (34) cooperating with an unlatch disc (24), the drawback action therefrom on the unlatch disc in the rest position being limited by an abutment (30) so disposed as to provide a small clearance (36) between the front face of the winding (26) and the opposite disc (24).
