Abstract
A device is provided for use with a circuit breaker that includes a magnetic trip bar adapted to move from a non-tripped position to a tripped position in response to a short-circuit condition, and move from the tripped position to the non-tripped position to reset the circuit breaker. The device includes a slider that has a first position and a second position, and a latch coupled to the magnetic trip bar and the slider. As the magnetic trip bar moves from the non-tripped position to the tripped position, the latch is adapted to move the slider from the first position to the second position to indicate that a short circuit trip has occurred. Numerous other aspects are provided.
