QO1520 Duplex 15/20 Circuit Breaker

QO1520 Duplex 15/20 Circuit Breaker

The QO1520 Duplex Plug-On Space-Saving Circuit Breaker is a practical solution for maximizing available panel space while delivering dependable overcurrent protection for residential and light commercial electrical systems. Designed as a Type QO duplex (tandem) circuit breaker, this unit combines 15-amp and 20-amp single-pole circuits into a compact, space-saving design, making it an excellent choice when additional branch circuits are needed without increasing panel size. Its plug-on installation allows for quick placement into compatible load centers, helping simplify maintenance, panel upgrades, and new installations. Built for reliable performance under normal operating conditions, the QO1520 provides a 10kA interrupting rating at 120VAC, helping protect electrical equipment and wiring from overloads and short circuits while maintaining the dependable operation expected from the QO product line.
