ABSTRACT:
An aircraft circuit breaker includes a housing having an opening, separable contacts, an operating mechanism structured to open and close the contacts, and a trip mechanism structured to cooperate with the operating mechanism to trip open the operating mechanism. The trip mechanism includes a first bimetal to trip open the operating mechanism responsive to a thermal fault, a second ambient compensation bimetal to compensate the first bimetal, and an arc fault trip circuit to trip open the operating mechanism responsive to an arc fault. An indicator includes an indicator portion and a leg disposed from the indicator portion. A spring biases the indicator portion. The second bimetal holds the leg of the indicator, thereby holding the indicator against the spring bias. The second bimetal releases the leg of the indicator responsive to the arc fault trip circuit and the arc fault, thereby releasing the indicator to the spring bias.
