Siemens 15 amps Combination Single Arc Fault Breaker

Combination Type AFCI differs from the Branch/Feeder AFCI in its ability to detect series arcing faults. The Branch/Feeder AFCI can only detect line-to-neutral and line-to-ground arcing faults. Combination AFCIs provide protection against the high-energy parallel (line-to-neutral and line-to-ground) arcing and low-energy series arcing. Combination = parallel + series arcing. Combination AFCIs protect downstream branch circuit wiring, cord sets and power supply cords. Murray Combination Type AFCI trip indicators provide a valuable analysis tool to help electricians pinpoint the type of trip.
