Dual Function Circuit Interrupter (DFCI) combines Ground Fault Circuit Interrupter (GFCI) and Combination Arc Fault Circuit Interrupter (AFCI) protection in a simple-to-apply and cost-effective solution. GFCI provides protection against overloads, short circuits, and ground faults, preventing electrical shocks. AFCI eliminates arc faults, preventing damage or fires from deteriorated wires, poor connections, or breaches in wire insulation. The DFCI meets the latest National Electrical Code (NEC) requirements. Its compact design, plug-on neutral, and short pigtail version speed up installation and reduce wire clutter.
