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.

Universal motor bracket for motor operators

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.

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.

Adjustment screw cover for motor operators

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.

Actuator mechanism for an external circuit breaker operating device

A circuit interrupter including separable main contacts, an operating mechanism interconnected with the contacts, and a housing in which the contacts and the operating mechanism are disposed. The housing includes a first attaching region and a mounting cutout. A shield is provided that includes a second attaching region attaching with the first attaching region for connecting the shield to the housing. The shield includes a tab adapted for covering the mounting cutout when the connection is made.

A DIN rail adapter for a circuit interrupter including a backplate having two guide members and two substantially planar stabilizing tab. The backplate further includes a first spring attachment region. A slider is slideably disposed between the guide members and the stabilizing tabs, and includes a second spring attachment region. A spring is disposed between the first and second spring attachment regions for biasing the slider in a first direction.

Circuit interrupter with improved DIN rail mounting adaptor

A circuit interrupter handle mechanism is disposed on the face of a molded case circuit breaker. The handle mechanism has a rotary handle, which may be rotated through approximately 90&deg; of rotation from a disposition of circuit interrupter conduction to a disposition of circuit interrupter non-conduction. The handle is not centered over the linear handle of the circuit interrupter per say, but rather is disposed in the upper left hand corner, so that a larger lever arm can be utilized. Furthermore, the larger lever has a handle opening into which the hasp of a lock may be placed to lock the circuit breaker in the open state for servicing and the like. Because of the length of the handle more hasps can be disposed therein than if the handle was disposed exactly in the center of the circuit breaker case. Lastly, the disposition of the circuit breaker rotary handle provides an indication of the conduction status of the molded case circuit breaker. If the handle is in a generally horizontal position, i.e., straight across the front of the circuit interrupter, that is an indication that the contacts of the circuit interrupter are open and that current therefore is blocked. If on the other hand the handle is 90&deg; displaced, in a rotational manner, to be parallel with the long longitudinal axis of the circuit interrupter, then an indication is given that the circuit interrupter contacts are closed and current is being conducted.

A circuit interrupter including separable main contacts, an operating mechanism interconnected with the contacts, and a housing in which the contacts and the operating mechanism are disposed. The housing includes a cover positioned atop a base. The cover includes a recessed region in which are formed a first hole and a second hole. The first hole and the second hole extend through the cover and into the base, and the second hole extends through the base. A retainment device is positioned within the recessed region, and includes a first opening positioned above the first hole and a second opening positioned above the second hole. The second opening has an opening diameter. A first screw is inserted into the first opening and the first hole. A second screw is for inserting into the second opening and the second hole. The second screw includes a threaded portion having a first diameter and a non-threaded portion having a second diameter. The first diameter is greater than the opening diameter, and the second diameter is smaller than the opening diameter.
