摘要： 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 closing springs controlling the circuit breaker contacts is made manually by means of a ratchet and pawl assembly. A logic plate interacts with a logic lever, an interlock link and a closing link to prevent the circuit breaker closing button from operating until and unless the closing springs have become fully-charged.

摘要： 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 operating handle and a ratchet and pawl assembly. A two-stage latching arrangement controls the retention and release of the pawl to retain and discharge the operating springs. The operating springs cannot become discharged until and unless the operating handle is in a fully retracted position.

摘要： 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.
