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 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 latches are interlocked with the operating springs drive shaft to prevent the discharge of the operating springs when the contacts are in the closed condition.
