Abstract
A refractory fiber insert within the cover of a molded case circuit breaker interfaces between the interior of the circuit breaker cover and the top surface of the circuit breaker arc chute to prevent the arc by-products generated within the arc chamber from re-entering the arc chamber. A shaped slot formed within the fiber insert automatically compensates for manufacturing tolerances to precisely locate the insert between the cover interior and the top surface of the arc chute.
