Circuit breaker having a movable and illuminable arc fault indicator

An aircraft circuit breaker comprising:

• a housing;
• separable contacts mounted in said housing;
• a latchable operating mechanism including a latch member which when unlatched opens said separable contacts;
• an overcurrent assembly responsive to selected conditions of current flowing through said separable contacts for unlatching said latch member to trip said separable contacts open;
• a movable and illuminable arc fault indicator having a first portion and a second portion internal to said housing;
• an arc fault trip actuator which when energized moves the second portion of said movable and illuminable arc fault indicator and unlatches said latch member to trip open said separable contacts;
• an arc fault current assembly responsive to selected arc fault conditions of current flowing through said separable contacts for energizing said arc fault trip actuator to move the second portion of said movable and illuminable arc fault indicator internal to said housing and the first portion of said movable and illuminable arc fault indicator external to said housing, and to trip open said separable contacts;
• and
• a light for illuminating the first portion of said movable and illuminable arc fault indicator.
