Abstract

The invention relates to a locking device (20) mounted directly on a circuit breaker (10) and configured for mounting different locks. The locking device (20) includes a yoke member (28), a slider member (32), a handle block (30) and a lock (48). When the locking device (20) is locked, the handle block (30) abuts the operating handle (14) in an engaged position corresponding to the operating handle (14) in the ON or OFF position. Thus, the locking device (20) locks the circuit breaker (10) in the OFF position or the ON position. The locking device (20) may further comprise a base member (22) disposed between the yoke member (28) and the housing (16). When it is desired to lock the circuit breaker (10) in the on position, the base member (22) is adapted to cover the push-to-trip button (70) on the housing (16).
