QN2150R - 150Amp Circuit Breaker

QN2150R - 150Amp Circuit Breaker

If you need a 150 Amp residential main circuit breaker with a reversed handle configuration, the QN2150R is built for that job. This 2-pole Type QNR breaker installs using a plug-in connection and provides dependable protection against overloads and short circuits with its thermal magnetic trip system. Rated for 120/240VAC with a 10kA interrupting capacity, it's intended for compatible residential electrical panels where a high-amperage main breaker is required.

The QN2150R is also HACR rated, making it suitable for residential HVAC applications as well as general electrical distribution. It operates at 50/60Hz, is rated for use in environments up to 40°C, and occupies four panel spaces. Whether you're replacing an existing breaker or completing a panel installation, confirming compatibility with your load center is always recommended before installation.
