Abstract
A handle operator slide and a motor operator slide are individually coupled with a charging mechanism to independently charge charging springs thereof. The charging mechanism is operative to charge the springs of a contact operating mechanism as the charging springs discharge. The charging mechanism includes a prop controlled by the condition of the operating mechanism to releasably sustain the charging springs in a fully charged condition, while the operating mechanism includes a hook to releasably sustain the breaker contacts open against the urgence of fully charged operating mechanism springs. Consequently, the circuit breaker is capable of executing multiple contact opening and closing operations without recharging the charging springs by either the handle or the motor via their respective slides.
