QN2150RH - 150Amp Circuit Breaker

QN2150RH - 150Amp Circuit Breaker

If you need a 150 amp main circuit breaker for a compatible residential panel, the QN2150RH is built for the job. This 2-pole, plug-in breaker is designed to protect electrical systems from overloads and short circuits with a dependable thermal magnetic trip unit that reacts to changing circuit conditions. Whether you're replacing an existing breaker or upgrading service equipment, this model delivers the performance expected in residential power distribution.

Rated 22kA at 120/240VAC, the QN2150RH is made to interrupt high fault currents before they can damage connected equipment or wiring. Its reversed handle configuration is intended for panels that require this specific design, and the plug-in construction helps make installation quicker in compatible load centers. The breaker is also HACR rated, making it suitable for approved heating and air conditioning applications. Operating at 50/60Hz and rated for 40°C ambient temperatures, it provides reliable protection in a wide range of residential electrical installations while occupying four panel spaces.
