Abstract
A split housing circuit breaker having an auxiliary switch for connection to remote indicators that reflect the condition of the breaker has an actuator moveable between ON, OFF, and TRIPPED. When the actuator is moved between the ON and OFF positions, an auxiliary switch lever holds an auxiliary switch plunger against its bias to a normally-open condition for the auxiliary switch. When the actuator is in the TRIPPED position or reset to the OFF position after a fault, the plunger is allowed to extend and the auxiliary switch moves to the dosed condition. A trip lever sub-assembly includes an auxiliary switch lever that selectively acts on the plunger, a trip lever that selectively holds the auxiliary lever against the plunger, and a pin and torsion spring to rotatably interconnect the two said levers.
