An indicator apparatus for a circuit breaker includes an indication mechanism and a latch mechanism mounted on a base, the base being mounted within the circuit breaker. The indication mechanism includes an indicator movably mounted on the base and being translatable along a longitudinal axis between a retracted position and an extended position, with the indicator in the extended position providing an indication visible from the exterior of the circuit breaker of a tripped condition of the circuit breaker. The latch mechanism includes a latch that is pivotable between a blocking position and a release position, with the latch in the blocking position being engageable with a ledge on the indicator to retain the indicator in the retracted position. The indicator is biased to the extended position by a first biasing device, and the latch is biased to the blocking position by a second biasing device. The abstract shall not be used for interpreting the scope of the claims.
