A reset lockout mechanism for a circuit breaker includes a linkage, a rocker, an armature, a solenoid, and a plunger. The linkage is positioned to move between an open position and a closed position. The rocker is selectively engageable with the linkage. The armature is selectively engageable with the rocker. The plunger is supported by the solenoid and operatively coupled to the armature. The plunger is movable between a first position and a second position.

The present disclosure discloses a miniature circuit breaker operating mechanism and a miniature circuit breaker. The operating mechanism includes an operating handle and a lock catch. The operating handle and the lock catch are separately rotatably connected to a circuit breaker housing. The operating mechanism further includes: a first connecting rod, which is rotatably connected with the circuit breaker housing, and the rotating shaft of the first connecting rod and the rotating shaft of the lock catch shares the axis or on the same axis; a moving contact is arranged on the first connecting rod; a second connecting rod; the second connecting rod is connected with the operating handle, and the second connecting rod, the lock catch and the first connecting rod cooperate with a linkage structure.

A circuit breaker design allows for the circuit breaker to have an overall width (i.e., measured along the circuit breaker's exposed outwardly-facing surface of its housing) that is narrower than achievable with known typical configurations, while at the same time still providing robust arc interruption capabilities. This is achieved in large part by providing a specific orientation of a moveable contact arm assembly and/or by providing a specific configuration of a current path within the housing.

A circuit breaker includes a line phase terminal, a load phase terminal, a line neutral terminal, a conductive path formed between the line phase terminal and the load phase terminal, the conductive path having an open configuration and closed configuration, a sensor, a linkage configured to move the conductive path between the open configuration and the closed configuration, a rocker selectively engageable with the linkage, the rocker configured to move the linkage between an open position and a closed position, and an arm selectively engageable with the rocker, the arm to prevent the conductive path from moving to the closed configuration unless the circuit breaker passes a self-test when movement of the rocker is detected. A trip operation of the circuit breaker includes a time delay based upon an amount of current on the conductive path detected by the sensor.
