Manufacturer: Schneider Electric North American Division, of Palatine, Ill.
Hazard: An AFCI is an electrical circuit protection device (circuit breaker) that detects electrical arcs from cracked, broken or damaged electrical insulation and shuts off power to the circuit before the arcing leads to a fire. An electronic component failure inside the AFCIs can cause the devices to not detect an electrical arc. Although the AFCIs will function as regular circuit breakers, they may not detect an arc fault, posing a safety risk to consumers.
Incidents/injuries: Schneider Electric is investigating one reported fire during a new home construction that may be related to this problem. No injuries have been reported.
