Abstract
Linear control apparatus for a circuit-breaker, the apparatus including a slidably-mounted tubular arm actuated by a solenoid, and a 'disengagement' first slide which presses against the tubular arm, the first slide being subjected to a first spring assembly. The control end of the drive rod is coupled to the tubular arm via at least one projecting portion passing through a respective longitudinal slot provided along the tubular arm. The control apparatus includes an 'engagement' second slide to which the drive rod is fixed via its projecting portion, the engagement second slide being subjected to an 'engagement' second spring assembly which displaces it from the circuit-breaker disengaged position to the circuit-breaker engaged position under the action of second control means.
