A circuit breaker comprises a housing containing a trip mechanism, a handle coupled to the trip mechanism and movable between on and off positions, and a lock-off mechanism capable of holding the handle in its off position. The lock-off mechanism includes a bracket adapted to be mounted on the circuit breaker housing adjacent the movable handle, and a slide mounted on the bracket for movement parallel to the movement of the handle when the handle is moved from the off position to the on position. The slide projects into the path of movement of the handle for engaging the handle, and the bracket and the slide form openings that register with each other when the projecting portion of the slide is proximate the handle in the off position. The registered openings are sized and shaped to receive the shackle of a padlock for locking the slide to the bracket, and thus locking the handle in the off position. |
