ARC RUNNERS SUITABLE FOR DC MOLDED CASE CIRCUIT BREAKERS AND RELATED METHODS

摘要

Circuit breakers include an arc chamber (11) and an arc chute (12) comprising a plurality of arc plates (25) in the arc chamber. The circuit breakers also include a line conductor assembly (45) with at least one arc runner (40) attached to a line conductor (32) in the arc chamber. The arc runner (40) can extend below but adjacent to a bottom arc plate (25b) to thereby guide a respective arc into the arc chute (12).
