Abstract
A circuit breaker is equipped with both a rotary operating handle and a power unit for selective manual and motor driven operation thereof. Mechanical and electrical control elements cooperate to insure a reliable operation in both the manual and motor driven operating modes, and, as a safety measure, to provide fool-proof, visual indications of the circuit breaker condition during the progressive stages of either operating mode. The power unit utilizes a permanent magnet, DC motor for improved performance and economies in design.
