Abstract (en)

[origin: EP0668601A1] The invention relates to a circuit-breaker operating device comprising an operating shaft (1) which, via a cam disc (7) mounted on the operating shaft, influences an operating lever connected to the movable contact of the circuit breaker. A closing spring, which exerts a torque on the operating shaft (1), is charged by means of a tensioning member and is kept in tensioned state by a latching arm (5) which is mounted on the operating shaft and cooperates with a closing latch. The cam disc (7) and the latching arm (5) are fixed on the operating shaft by means of splines, a so-called blind spline being provided to ensure the correct mutual angular position between the disc (7) and the arm (5). <IMAGE>
