摘要： A circuit breaker includes line and load terminals, separable contacts electrically connected between the line and load terminals, and a line neutral pigtail. An operating mechanism including an operating handle is adapted to open and close the contacts. A trip circuit responds to current flowing through the contacts and cooperates with the operating mechanism in response to predetermined current conditions to open the contacts. The trip circuit is powered from the line terminal and the line neutral pigtail. A solenoid includes a plunger and a coil, which is energized from the line terminal and the line neutral pigtail. The plunger engages the operating handle when the coil is not energized to prevent movement of the handle from the open to the closed position thereof. The plunger disengages from the operating handle when the coil is energized to permit movement of the handle from the open to the closed position thereof.
