Overview
The Square D HOM120CAFI is a 20 A, 120 VAC, single-pole Homeline combination arc-fault circuit interrupter with plug-in mounting and a pigtail neutral. It combines series- and parallel-arc detection with thermal-magnetic overload and short-circuit protection and a 10 kA AIR rating.
Key Features
-
Protection: Combination AFCI protection detects hazardous series and parallel arcing while the thermal-magnetic trip responds to overloads and short circuits.
-
Installation: The breaker plugs into compatible Homeline equipment and uses a screw-clamp load terminal plus a factory pigtail connection to the panel neutral bar.
-
Compatibility: Use only in Square D Homeline load centers and CSEDs specifically listed for pigtail-neutral HOM-CAFI breakers.
-
Performance: Rated 20 A, 1 pole, 120 VAC and 10 kA AIR for dwelling branch-circuit arc-fault protection.
