Abstract: A mounting bracket for the motor within a motor operator for a circuit breaker may be secured within the motor operator's housing a first orientation, thereby permitting it to support a first type of motor. Placing the mounting bracket within the housing in a second orientation permits the mounting bracket to accommodate a second type of motor.

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.

Abstract: A sliding cover plate for the adjustment screws of a circuit breaker is slidably mounted on the housing of a motor operator. The sliding adjustment plate includes snap-in tabs for engaging slots within the motor operator housing, permitting the cover to be snapped in place, and then slidably moved between a position wherein the adjustment screws are covered, and a position wherein the adjustment screws are exposed. The cover may be secured in the position wherein the adjustment screws are covered. The cover includes a first portion defining apertures corresponding to two adjustment screws, and a third, detachable portion defining an aperture for a third adjustment screw, thereby permitting the cover plate to be utilized with both three-pole and four-pole circuit breakers.

Abstract: An actuator mechanism, for a circuit breaker having an operating handle, which includes a slider assembly and a mounting plate assembly. The slider assembly has a rigid, generally planar member with at least one notch. The mounting plate assembly has at least two generally parallel, spaced flanges and is structured to mount on the circuit breaker housing. One of the at least two flanges is structured to cooperate with the notch to allow the slider assembly to be slidably coupled to the mounting plate between the at least two flanges.
