Detects arcing faults that standard circuit breakers are unable to detect. Intended to mitigate the effects of parallel arcs (line-to-ground or line-to-neutral) by de-energizing the circuit when an arc-fault is detected. Industry exclusive LED light to indicate type of trip. With Time-Saver Diagnostics, advanced trip indication technology, identifying the type of fault that last occurred. 2 LEDs appear for 5 secs each time the CAFCI is turned on, up to 30 days after the last trip to indicate last known trip condition. One LED means arcing fault. Two LEDs means arcing fault to ground. Wire range - #14 to #8 AWG #12 to #8 AWG. 120VAC. Interrupting rating of 10 kA. UL listed, HACR, SWD Rated.
