ABSTRACT:
This invention relates to a high ampere-rated circuit breaker which meets the electrical code requirements of the world market. The powerful operating springs controlling the circuit breaker contacts are restrained by the interaction of a cradle operator and a two stage latching assembly. The latching assembly includes a primary and a secondary latch to insure against nuisance tripping.
