Compact circuit breaker incorporating a polymer current limiter
 A compact current limiting circuit breaker utilizes a polymer current limiter, an arc rail and an arc gap for effective overcurrent protection. Upon the occurrence of contact separation an arc is drawn between the circuit breaker contacts and driven toward an arc rail. Commutation of the arc from the stationary contact to the arc rail effectively changes the current path to incorporate the polymer current limiter which rapidly suppresses the overcurrent. Circuit isolation is achieved by extinction of the arc within the arc gap between the movable contact and the arc rail.
