Abstract
A circuit breaker ( ) includes a sensing circuit ( ), a control circuit ( ), an actuator ( ), an operating mechanism, and an interlock mechanism ( ). The sensing circuit ( ) is configured to generate the sense signal representative of a power signal flowing through a power circuit ( ). The control circuit ( ) has a frame ( ) and is configured to receive the sense signal and to provide a trip signal on a first terminal ( ). The actuator ( ) is external to the control circuit frame ( ) and has a second terminal ( ) coupleable to the first terminal ( ). The actuator ( ) is configured to receive the trip signal on the second terminal ( ). The operating mechanism is coupled to the actuator ( ) and is configured to open and close the power circuit in response to actuation of a lever ( ). The actuator ( ) is configured to actuate the lever ( ) in response to the trip signal. The interlock mechanism ( ) is coupled to at least one of the actuator ( ) and the operating mechanism and is configured to actuate the lever ( ) when the first terminal ( ) is not coupled to the second terminal ( ).
