Abstract (en)
Circuit breaker (1) comprising an electric circuit having at least a fixed electric contact (25) and at least a movable electric contact (24), wherein the movable contact (24) is rotatable along a trajectory (T) lying in a plane and defined between a first operating position, in which the movable contact (24) abuts against the fixed contact (25) and a second operating position, in which the movable contact (24) is positioned at a predetermined distance from the fixed contact (25), wherein the circuit breaker (1) further comprises a holding element (20) for the fixed contact (25). The circuit breaker (1) further comprises two generally plate-like parallel elements (27, 28), made of ferromagnetic material, positioned at a certain mutual distance on opposite sides with respect to said plane.
