Circuit breaker assembly with inhibitor assembly

A circuit breaker assembly including first and second circuit breakers each having toggle switch assemblies movable between ON and OFF positions. The toggle switch assemblies have connectors coupled thereto for preventing both circuit breakers from being in the ON position at the same time.

A saddle assembly (10) for a circuit breaker comprising a saddle base (22), at least one stab terminal (14) and two resilient tabs (50, 52) in facing alignment for releasably securing the at least one stab terminal (14) to the saddle base (22), wherein the engagement of the two resilient tabs (50, 52) with the stab terminal (14) releasably secures the at least one stab terminal (14) to the saddle base (22).

An electronic circuit interrupter is protected against thermal damage upon loosening of the lug connectors that connect the circuit interrupter with the load circuit. Thermal sensing elements attached to the lugs connect with the circuit interrupter trip unit to initiate circuit interruption when the temperature sensed exceeds a predetermined value.

An arc isolation shield for molded case circuit breakers is inserted between the circuit breaker case and cover and attached to one leg of the operating cradle. The knee of the circuit breaker moveable contact arm contacts the bottom of the shield and moves the shield in unison with the contact arm to protect the contact arm, contact braid and operating spring upon contact separation under severe overcurrent conditions.

Molded case circuit breaker accessories using slightly modified circuit breaker cases are described. Several of the accessories utilize a microswitch to provide remote indication of an auxiliary function. One modification of the circuit breaker case includes upstanding posts to capture and position the microswitch while a further modification utilizes the magnetic trip unit adjustment screw and a support plate.
