    摘要: A motor operator interface assembly allows a large industrial-rated circuit breaker to be manually operated between its ON and OFF conditions as well as electrically driven by a motor operator. The interface assembly includes a motor driver plate that connects and disconnects the circuit breaker operating handle from the motor operator unit to allow either manual or motor-driven operation. A drive pawl and drive plate insure resetting the circuit breaker.

    摘要: A compact molded case circuit breaker operating mechanism crossbar assembly allows a unitary crossbar design to be used within a wide range of circuit breaker ampere ratings. A common phenolic crossbar and a metal staple are used for the higher ratings. An L-shaped filler in combination with the crossbar and staple are used to adapt the crossbar to the staple for the lower ratings.

    摘要: A molded case circuit breaker utilizes a thermally responsive trip unit for providing long and short-time overcurrent protection and a magnetically responsive trip unit for instantaneous or short-circuit protection. An electrically and thermally insulative lever interfaces between the thermal element and the circuit breaker trip response bar to linearize the movement of the thermal trip element in response to circuit current.

    摘要: The secondary latch of a molded case circuit breaker latching arrangement is formed from a latching pin assembly with a solid metal latching sphere rotatably mounted at one end thereof. The latching sphere contacts the operating mechanism latching plate to provide a low-friction latching force to the circuit breaker operating mechanism. The latching sphere contacts the latching plate and is continuously lubricated by means of a lubrication reservoir integrally-formed within the latch pin assembly.

    摘要: A molded case circuit breaker of the type containing an electronic trip unit and a combined acutator-accessory unit to articulate the circuit breaker operating mechanism employs an optimum cradle configuration within the circuit breaker operating mechanism. The optimized cradle interacts with the circuit breaker latch assembly to substantially reduce the tripping force required to articulate the operating mechanism.

    摘要: A compact circuit breaker containing an electronic trip unit employs an actuator-accessory unit to articulate the circuit breaker operating mechanism and separate the circuit breaker contacts to interrupt current within a protected circuit. A tolerance compensating spring is attached to the actuator-accessory unit trip armature to precisely set the separation gap between the tip of the armature and the actuator-accessory trip actuator arm.

    摘要: A rotatable trip test assembly unit for molded case circuit breakers consists of a unitary plastic part that cooperates with the internal structure of the circuit breaker cover to provide return spring bias to the trip test button. The trip test assembly unit rotates about a pivot and strikes the circuit breaker trip bar to thereby articulate the circuit breaker operating mechanism and separate the circuit breaker contacts. The interaction between a cam-follower on the assembly unit and a cam-shaped piece within the circuit breaker cover automatically returns the trip test button to its initial position upon release.
