Square D Homeline 15 Amp 1-pole Plug-On-Neutral Combination Arc Fault Circuit Interrupters (CAFI) helps keep people and property safe from the effects of dangerous arcing. These arcs typically occur out of sight; inside walls or electrical devices, day or night. Designed for reliability, the Homeline Plug-on Neutral CAFI Circuit Breaker connects directly to the neutral bar, providing a time and labor-saving installation. Several advantages from the Plug-on Neutral design are fewer connections which lead to faster installation and an innovative neutral clip eliminates pigtails which in turn frees gutter space. The Square D CAFI circuit breaker uses a state-of-the-art Arc Detection Technology to continuously monitor the circuit and quickly turn-off the power (trip) when a dangerous condition is detected. Best of all, this technology is combined with Square Ds robust and reliable short circuit/overload protection systems in a small, compact package. Engineered for Value and built for Quality, the market leading Square D brand Homeline Combination Arc Fault Circuit Interrupter combine time-tested performance with state-of-the-art technology to provide one of the safest circuit breakers available today.
