Abstract:
1. A circuit breaker comprising: a line connection; a load connection; separable contacts electrically connected between said line connection and said load connection; a line neutral connection; an operating mechanism adapted to open and close said separable contacts, said operating mechanism moving between an open position wherein said line connection is electrically disconnected from said load connection and a closed position wherein said line connection is electrically connected to said load connection; a trip circuit responsive to current flowing through said separable contacts and cooperating with said operating mechanism in response to predetermined current conditions to open said separable contacts, said trip circuit being powered from said line connection and said line neutral connection; and an electro-mechanical device including a coil and a plunger, said coil being energized from said line connection and said line neutral connection, said plunger directly contacting said operating mechanism when said coil is not energized to prevent movement of said operating mechanism from the open position to the closed position thereof, said plunger being separated from said operating mechanism when said coil is energized to permit movement of said operating mechanism from the open position to the closed position thereof.
