Claim Text:
1. A device 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 comprising: a magnetic trip bar extension of the magnetic trip bar having an edge and a first surface, wherein when a short-circuit trip event occurs, the magnetic trip bar extension rotates in a clockwise direction; a housing having a window to visually indicate presence or absence of a magnetic or short circuit trip event; a slider that comprises a first position and a second position, wherein the slider is disposed in the housing, the slider having a first end visible through the window when the slider is in the second position to visually indicate that the magnetic or short circuit trip event has occurred and with an absence of the first end of the slider into the window when the slider is in the first position to visually indicate that the magnetic or short circuit trip event has not occurred; and a latch coupled to the magnetic trip bar and the slider, wherein 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, wherein the latch is configured to prevent the magnetic trip bar from being reset until the slider is manually moved from the second position to the first position, wherein the latch includes a first end and a second end, the first end includes a first beveled surface and a second beveled surface, the second end includes a tab having a third beveled surface, wherein when the short-circuit trip event occurs the first surface of the magnetic trip bar extension slidingly engages the first beveled surface of the latch, the second beveled surface of the latch engages the edge of the magnetic trip bar extension, which prevents the circuit breaker from being reset and wherein if a user manually pushes the slider, the third beveled surface causes the second beveled surface of the latch to disengage the edge of the magnetic trip bar extension, which allows the magnetic trip bar extension to rotate counterclockwise and return to its original position, thereby allowing the circuit breaker to be reset.
