CIRCUIT BREAKERS WITH MOVING CONTACT HAVING HEEL-TOE ACTION

摘要

Circuit breakers with moving contacts having heel-toe action are configured to direct arcing across a small portion of a stationary contact surface to an adjacent arc chute to thereby alleviate deterioration due to arcing and improve conductivity of a major portion of the stationary contact and moving contact surface over time.
