ABSTRACT:
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.degree., 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.
