ABSTRACT:
This invention relates to a high ampere-rated circuit breaker which meets the electrical code requirements of the world market. The charging of the powerful operating springs controlling the circuit breaker contacts is made manually by means of an externally accessible handle operator assembly. A ratchet and pawl assembly allows the application of a large spring charging force by virtue of a short displacement of the handle operator.
