Abstract
A circuit breaker auxiliary device is housed in its own separate enclosed container and is accessible by a drive pin through an opening in the container mounting surface. A drive pin is inserted into an opening in a circuit breaker housing mounting surface. The container is snap-fitted flushly to a side of the circuit breaker housing. The internal trip mechanism of the circuit breaker and the operative mechanism of the auxiliary device communicate via the drive pin cooperatively linked to each mechanism and operating through the aligned openings in the container and the circuit breaker housing.
