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