Abstract (en)

[origin: EP0555158A1] A bell-crank operating mechanism (28) of a circuit breaker with moulded case includes a pivoting grip (23) for opening or closing the circuit breaker and rearming the latch (26) following tripping. The grip (23) carries a rearming roller (38) which cooperates with a cam surface (39) of the latch (26), which surface has a first cam section (41) and a second cam section (42) which are separated by a point of change of slope (40). The second section corresponds to the rearming position and the slope of this section is chosen so as to obtain a stable position of rearming of the grip (23). <IMAGE>
