CA 2157713

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 a ratchet and pawl assembly. A logic plate interacts with the operating springs charging gear and a logic lever interacts with the ratchet and pawl assembly to prevent the charge indicating flag from signaling until the operating springs have become fully charged.
