Abstract
A trip indicator is for a circuit breaker having a housing including first and second openings, separable contacts and an operating mechanism having an operating handle for opening and closing the separable contacts. The trip indicator includes a trip indicating member with a first end having a trip indicia and a second end with first and second projections. The first projection is engaged by a cradle of the operating mechanism when the separable contacts are not tripped, in order to prevent the trip indicia from being viewable at the second opening of housing. The first projection is disengaged and released when the separable contacts trip, causing the trip indicating member to move in order that the trip indicia is viewable at the second opening. A locking feature in which the second projection engages and locks operating handle, is also disclosed.
