Abstract

A circuit breaker which utilises auxiliary power stored in a wind-up spring motor drive has the switch elements coupled to a rotatable shaft, an auxiliary position in which the circuit is earthed being provided in addition to the ON and OFF positions. The spring drive is coupled between the shaft and the switch operating member, and incorporates a disengageable pawl. The spring (8) of the spring drive is disposed coaxially around the shaft (6). The switch operating member includes a sleeve (12,13) disposed around the shaft and attached to a control disc (11), one end of the spring being attached to the sleeve. The other end of the spring is coupled to a dog attached to a locking disc (9) having a pair of interlock members (14,15), each having two links, bearing on its periphery. Depending on the switch position, either both links of one interlock member, or one link of both members, engage the periphery of the locking disc, the interlock members being disengageable by rotating the control disc.
