Conductive polymer current-limiting fuses. when connected in series with conventional mechanical circuit breakers, exhibit extremely low let-through values. Particularly, conductive polymer current-limiting fuses based on conductive elastomeric material are disclosed which exhibit extremely low let-through values, namely less than 5,000 A2s with a switch current of 1.79 kAp, preferably less than 2,500 A2s, most preferably no more than 2,250 A2s.
