41PR 6015 ABSTRACT OF THE DISCLOSURE A spring powered charging mechanism is operatively coupled with a spring powered, circuit breaker contact operating mechanism such that charging of the operating mechanism springs is powered exclusively by the charging mechanism springs as they discharge. The charging mechanism includes a prop controlled by the condition of the operating mechanism to releaseably sustain the charging springs in a fully charged condition, while the operating mechanism includes a hook to releaseably 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.
