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 automatically by means of an electric motor. The circuit breaker operating handle connects with the operating springs through a motor operator interface unit to allow manual charging of the operating springs upon stalling of the electric motor.
