Abstract
The invention relates to a fast closing mechanism of a circuit breaker with an operating handle. The mechanism comprises an energy storage spring disposed between the handle and an intermediate lever supporting a transmission rod. A retaining plate operates in conjunction with a pin of the handle to occupy either an active position locking the rod during loading of the spring, or a retracted position unlocking the rod allowing the spring to be released at the end of closing travel.
