The invention relates to controlling a circuit breaker by means of a drive mechanism circuit for operating a circuit breaker by rotating a main operating shaft (4). The drive mechanism comprises a trigger circuit breaker drive mechanism (1) delivering considerably less power than that required for operating the circuit breaker, and associated with an assembly including a disengagement first spring (6), an engagement second spring (12), and a recocking motor (14) for recocking the springs which are disposed, on being released, to drive the main shaft (4) through 180 DEG , with the release of the springs being controlled by motion of an outlet member (2) of the trigger drive mechanism (1). The invention is applicable to the operating circuit breakers. |
