Abstract
A rotary handle operator for a circuit breaker includes a lock plate having a live spring, formed as one piece with the lock plate, for biasing the lock plate in its unlocked position. With the lock plate in this unlocked position, rotation of the rotary handle operator's handle will actuate movement of a sliding member within the rotary handle operator, thereby moving the operating lever of the circuit breaker from its on position to its off position, and vice versa. When the rotating handle is in its off position, the lock plate may be pivoted against the bias of the springs so that the lock plate fits within a slot in the housing of the rotary handle operator, thereby resisting movement of the handle. In this position, an aperture dimensioned and configured to receive the shackle of a lock protrudes upward from the handle, permitting insertion of a lock to secure the lock plate in this locked position.
