摘要： An improved shock resistant auxiliary switch mechanism for a circuit breaker includes a common conductor having a conduction plate that is slidably translatable between electrically conductive contact with first and second conductors. The conduction plate is biased by a spring in a direction toward contact with the first conductor. An improved shock resistant circuit breaker including the improved auxiliary switch mechanism includes a crossbar that is operatively engageable with the conduction plate to releasably retain the conduction plate in a position in contact with the second conductor. When the circuit breaker is in an ON position, the conduction plate is operatively interposed between the crossbar and the bias of the spring.

摘要： The helical contact compression springs of a circuit breaker are preassembled in a contact clip for easier assembly of the circuit breaker. The bottom wall of an elongated trough formed by the clip is pierced by holes forming cylindrical protrusions extending into the trough. The clip is placed over the springs supported in a row in a fixture. A die head presses on the spring clip to compress all the springs and then simultaneously insert punches into the holes in the clip to expand the protrusions and secure the springs to the clip. The fixture includes a slide mounted on guides for movement between a loading position and an operating position under the die head. A support block is pivoted on the slide to present one of two sets of spring recesses for circuit breakers having different current ratings with the slide in the loading position.

摘要： An electrical operator includes a housing; a motor driven ball screw for operating the handle of a circuit breaker in an electrical mode of operation, and a handle extension for operating the circuit breaker handle in a manual mode of operation; a slider plate sliding through an opening of the housing between an intermediate position enabling the manual mode of operation, an inner position enabling the electrical mode of operation, and an outer position wherein the manual and electrical modes are disabled; and a cantilevered latch spring member connected to the slider plate. The free end of the cantilevered latch spring member engages the housing at about the opening thereof to stop the slider plate in its manual intermediate position. The free end of the cantilevered latch spring member deflects toward the slider plate to disengage from the housing and permit the slider plate to enter the inner electrical position thereof.

摘要： An electrical switching apparatus includes a circuit breaker device having a molded housing with line and load ends, plural terminals disposed from the housing, and first and second handle devices. The terminals electrically and mechanically engage a circuit breaker mounting block. The first and second handle devices engage the housing at or about the respective line and load ends. The handle devices remove the circuit breaker device from the mounting block. Each of the handle devices includes an insulative barrier having a first portion, a second portion and a third portion. The first portion at least partially covers a corresponding one of the housing ends. The second portion is coupled to the housing at or about the corresponding one of the housing ends. The third portion is structured to be manually grasped in order to pull the insulative barrier together with the circuit breaker device away from the mounting block.

摘要： An operating mechanism is for a circuit breaker housed by an enclosure assembly including a panel movable between a closed position and an open position. The operating mechanism includes a linkage and an operating member. The operating mechanism is coupled to the handle of the circuit breaker to provide operation of the handle from the exterior of the enclosure when the panel is closed. The operating member includes a first end having an engaging portion coupled to the linkage of the operating mechanism, and a second end structured for gripping by a user. The operating member enables the handle of the circuit breaker to be operated, without requiring the use of separate hand tools, when the panel of the enclosure is open and the handle portion of the operating member is actuated.
