Abstract
A remote controlled circuit breaker including a mechanism linked to a handle by a drive lever equipped with a roller cooperating with a recharging cam of an energy storage system including a spring. A bearing surface is arranged to block the roller in the charged position, without requiring the presence of a special latching stage, since the line of action of the reaction R of the roller passes via the transmission shaft of the cam. A step-by-step motor of the vibrating type drives the transmission shaft in rotation, and enables almost instantaneous stopping of the cam when the roller is in contact with the bearing surface.
