ELECTROMAGNETIC CONTACTOR ARC CHUTE

摘要

ELECTROMAGNETIC CONTACTOR ARC CHUTE of the Invention An arc chute for a clapper-type electromagnetic D.C. contactor having a closed off top wall with tapered and angled holes therethrough directing jets of air, caused by the arc when the contact tips separate, to the front of the arc chute thereby preventing the arc from moving directly above the contactor and as a result decreasing overhead clearance between contactors and, further improving the upper limit on fault current interruptions.
