ABSTRACT:
A circuit breaker for interrupting electrical current flowing through a line conductor to a load terminal in response to the detection of a current overload, ground fault and/or arcing fault. The circuit breaker has a trip circuit to generate a trip signal, a releasably latchable trip lever, and a latching mechanism. The trip lever is moveable between a latched position and a tripped position. In the latched position, the trip lever engages the latching mechanism and the electrical current flows through said circuit breaker. When a fault is detected by the trip circuit, a trip signal is send to the latching mechanism. Upon receiving the trip signal, the latching mechanism disengages the trip lever allowing the trip lever to slide into the tripped position and interrupting the current flow through the circuit breaker.
