Square D QO Dual Function Circuit Breaker 15

QO 1-pole plug-on neutral dual function circuit breaker. Space and labor saving device, engineered to meet prevailing NEC requirements. This device combines two critical technologies; Combination Arc Fault protection and Ground Fault protection (class A), in a single, easy-to-install device. The NEC now requires both combination arc fault and ground fault protection on all 1-Pole, 15-Amp and 20-Amp kitchen and laundry circuits. Prior to the release of this new device, a contractor or homeowner's only choice would have been to use a combination arc fault circuit breaker in conjunction with an expensive, bulky ground fault receptacle. Dual function circuit breaker helps reduce cost and eliminates the hassle of using two separate devices to provide this essential protection. Designed for reliability, 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. Integrated with time saver diagnostics, a unique feature that provides additional circuit information and minimizes troubleshooting at the touch of a button.
