Claim:
1. A trip mechanism of a circuit breaker, comprising: a trip lever rotatably mounted in the circuit breaker and configured to transition from an on position to a tripped position; a latching member movably mounted in the circuit breaker and configured to releasably hold the trip lever in the latched position; and an armature disposed in the circuit breaker adjacent to the latching member, the armature configured to compel the latching member away from the trip lever, thereby causing the trip lever to transition from the latched position to the unlatched position, when a short-circuit condition occurs; wherein the latching member is further configured to catch the trip lever during the transition from the on position to the tripped position, and catching the trip lever halts further progress of the latching member within the circuit breaker; wherein the latching member has a signal flag integrally formed therewith for providing a visual indication that the circuit breaker has been tripped; and wherein the latching member is a yoke having a form of a U shape and the signal flag extends from a top portion of the yoke.
