Zusammenfassung: | A circuit breaker (1) includes a housing (3); separable contacts (47) mounted in the housing (3); a latchable operating mechanism (22) including a latch lever (77) which when released opens the separable contacts (47); and an overcurrent assembly (53) responsive to selected conditions of current flowing through the separable contacts (47) for releasing the latch lever (77) to trip the separable contacts (47) open. The circuit breaker (1) also includes an arc fault indicator (37,135); an arc fault trip actuator (119) which when energized moves a first indicator latch (287) for actuating the arc fault indicator (37,135) and a second latch (229) for releasing the latch lever (77) to trip the separable contacts (47) open; and an arc fault current assembly (39) responsive to selected arc fault conditions of current flowing through the separable contacts (47) for energizing the arc fault trip actuator (119) to actuate the arc fault indicator (37,135) and to trip the separable contacts (47) open. |
