ABSTRACT:
A "U" shaped arc chute, formed in a single piece stamping, with louvered openings at the center section. The louvers cool and safely direct gases, generated during short circuit operation of a circuit breaker, away from the metal front of circuit breaker panel board, thereby reducing the likelihood of an electric arc striking between the circuit breaker line terminal contact and the circuit breaker enclosure. The louvered arc chute is durable, and provides a barrier to prevent access to the interior of the circuit breaker.
