摘要:
A circuit breaker having a handle stop for restraining the handle in a "tripped" or central position after the circuit breaker is electrically tripped to mechanically and visually indicate the tripped position.Also, an actuator is supported within the case of the circuit breaker and pivoted by the linkage mechanism (only when the latter is electrically tripped). During manual opening and closing of the circuit breaker contacts, the linkage mechanism does not pivot the actuator.Pivoting of the actuator (upon electrical tripping of the linkage mechanism) causes the actuator to engage and activate an auxiliary switch.When the circuit breaker handle is moved to the "off" position from the "tripped" or central position, the linkage mechanism simultaneously releases the actuator and the auxiliary switch is deactivated.
