An aircraft circuit breaker includes a housing; separable contacts mounted in the housing; a latchable operating mechanism including a latch member which when unlatched opens the separable contacts; and an overcurrent assembly responsive to selected conditions of current flowing through the separable contacts for unlatching the latch member to trip the separable contacts open. A movable and illuminable arc fault indicator has a first ring portion and second leg portions internal to the housing. An arc fault actuator which when energized moves one of the second leg portions. An arc fault current assembly responds to selected arc fault conditions of current flowing through the separable contacts to energize the arc fault actuator to move the second leg portions internal to the housing and the first ring portion external to the housing. The arc fault current assembly includes a light for illuminating the first ring portion.

An indicator reset tool is for a movable arc fault indicator of a circuit breaker. The circuit breaker further includes a housing enclosing separable contacts, an operating mechanism for opening and closing the separable contacts, and an operating handle protruding through an opening in the housing. An actuator actuates the movable indicator arc fault indicator and actuates the operating mechanism to trip the separable contacts open. The indicator reset tool includes a reset member having a first end with an indicator engaging portion structured to depress and reset the movable arc fault indicator. The second end of the reset member includes a handle portion for gripping by a user.

A circuit breaker includes a housing; separable contacts mounted in the housing; and an operating mechanism for opening and closing the separable contacts. An overcurrent assembly is responsive to selected conditions of current flowing through the separable contacts and actuates the operating mechanism to trip open the separable contacts. A bonnet forms a U-shape which surrounds the separable contacts and which cools and splits an arc when the operating mechanism trips open the separable contacts. A first bonnet piece forms a first leg of the bonnet, and a second bonnet piece forms a second leg and a base of the bonnet.

A subminiature circuit breaker is equipped with an arc fault auxiliary switch actuated by the arc fault trip motor through an indicator actuator that also deploys a pop-up arc fault indicator. An additional auxiliary switch actuated by the drive link on the toggle mechanism provides an indication of the open/closed state of the circuit breaker separable contacts. Both the arc fault auxiliary switch and the contact state auxiliary switch are mounted on the outside of the subminiature circuit breaker housing and are operated by an operating member and a pivoted member, respectively, extending through openings in the housing.

An improved electrical switching apparatus comprises a plurality of electrical switching assemblies in a ganged configuration. A bridging device mechanically connects together the actuator devices of the electrical switching assemblies to cause the simultaneous tripping of all of the electrical switching assemblies when an overload or an arc fault is detected on any electrical switching assembly of the gang.
