Abstract
A circuit breaker is equipped with a motorized control acting on an operating member oscillating between a loaded position and a closed position, passing via a closing dead point position. When the unit is open or reset by means of the motorized control, the operating member is moved to an indexed position close to the closing dead point position, so as to minimize the closing time. The circuit breaker also has an opening dead point position. To minimize the opening-closing cycle time, the motor drives the operating member from the closed position to an indexed turning position situated between the opening dead point position and the loaded position, before changing direction.
