ABSTRACT:
Arc suppressing means for current limiting circuit breakers wherein an arc generated between both movable and fixed contacts by an excess current at the time of short-circuiting is magnetically driven by a member extending from the contact part of fixed contactor to an arc running plate in the right angle relation to the plate with a shortened time of arc's staying at the contact part and a shortened time of arc's traveling from the member to a deion grid along the running plate to quickly obtain an elevated arc voltage and to thereby effectively elevate current limiting effect.
