QN2150H - 150Amp Circuit Breaker

QN2150H - 150 Amp Circuit Breaker

The QN2150H is a 150-amp, 2-pole Type QN plug-in circuit breaker designed for residential main load center applications requiring dependable overcurrent protection. With a 22kA interrupting rating at 120/240VAC, it is a solid choice for installations where available fault current exceeds the limits of standard breakers. Its thermal-magnetic trip mechanism responds to both sustained overloads and short circuits, helping protect wiring and connected equipment under abnormal electrical conditions.

Designed for 50/60Hz electrical systems and rated for operation in 40°C environments, the QN2150H is also HACR rated, making it suitable for your compatible heating, air conditioning, and refrigeration equipment. The breaker installs using a plug-in connection and occupies four panel spaces in compatible load centers.
