Circuit breaker having a movable and illuminable arc fault indicator |
摘要 |
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.
