Abstract (en)
[origin: CA1161889A] Disclosed is a power drive for electric switchgear, for example, protective low-voltage breakers. The power drive comprises a support plate and a drive slide which is guided between the support plate and the top or front side of the switchgear. The drive slide includes side walls into which a projection located on the top side of the switchgear extends for guiding the drive slide on the switchgear. The drive slide cooperates with the switchgear actuating handle through an opening having curved surfaces. The power drive includes a U-shaped leaf-spring which extends transversely to the direction of motion of the drive slide and which provides for elastic transmission of force from a crank coupled to a gear box to the actuating handle of the switchgear.
