Abstract
A circuit breaker is equipped with a current limiting arc runner for effective overcurrent interruption without additional heating under quiescent operating conditions. Upon contact separation, an arc is drawn with the endpoints of the arc being initially rooted on the set of open contacts. Further opening of the contacts commutates the arc onto the current limiting arc runner to suppress the circuit current.
