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 the trip bar when the first terminal is not coupled to the second terminal.
