QO115DFC Circuit Breaker, Dual Function, 15-Amp, 1-Pole, 120V

The Square D QO115DFC is a single-pole dual-function circuit breaker that combines arc-fault and ground-fault protection in one compact device. Designed for residential and light-commercial electrical panels, this breaker protects 120-volt circuits from overloads, arc faults, and ground faults while fitting neatly into standard QO load centers with a single-space footprint. It addresses critical electrical safety concerns by integrating Combination Arc Fault Interrupter (CAFCI) technology with Class A ground-fault protection, eliminating the need for separate protective devices and simplifying panel layouts.

This breaker is ideal for protecting lighting circuits, receptacle circuits, and small-appliance loads. Its thermal-magnetic trip mechanism provides precise overload response, while the integrated arc-fault detection actively monitors wiring conditions to reduce the risk of fires caused by hidden defects. The plug-in connection style makes installation straightforward, and the time-saver diagnostics feature indicates the type of fault that last occurred on the circuit, helping electricians and homeowners quickly diagnose electrical issues.

Features and Benefits

• Dual-Function Protection: Combines CAFCI arc-fault and Class A ground-fault protection in a single unit, saving space and reducing panel complexity.
• Time-Saver Diagnostics: Displays the type of fault that last occurred on the circuit, making troubleshooting faster and more accurate.
• Single-Pole, 1-Space Design: Optimizes panel real estate, allowing more circuits in the same load center without sacrificing protection.
