Device for controlling a breaker

摘要

A device for controlling a breaker comprising a weight (48) provided in the vicinity of a releasing trigger (19) and an auxiliary spring (50 )for urging the weight (48) so that the weight (48)is in contact with the releasing trigger (19). An equivalent mass of the weight (48)is about one-third of an equivalent mass of the releasing trigger. When the releasing trigger (19)is in contact with a pin (45) of a releasing latch (18), the weight (48)rebounds but the releasing trigger (19)is settled without rebounding. By such a structure, the rebound of releasing latch and the releasing trigger is prevented when these are engaged, whereby a time for closing a circuit is shortened.
