Abstract (en)
[origin: EP0314540A1] An opening device for a low-voltage circuit-breaker includes, in each pole, a switch bar (40), a pair of fixed contacts (26, 28) communicating with the connecting areas (30, 32), a double-opening rotary contact (14) extending into a housing (41) of the bar (40), and two arc-quenching chambers (36, 38) disposed on either side of the bar (40). Two contact compression springs (60, 62) ensure elastic positioning of the rotary contact (14) along the longitudinal direction of the pole. The pivoting of the rotary contact (14) takes place about a dummy axle (16) mounted so as to float in relation to the fixed axle of rotation of the bar (40). <IMAGE>
