QNRH200 - 200Amp Circuit Breaker

QNRH200 - 200Amp Circuit Breaker

The QNRH200 is a 2-pole, 200-amp Type QNRH plug-in residential main circuit breaker engineered to provide dependable overcurrent and short-circuit protection for your compatible residential electrical distribution systems. Featuring a thermal magnetic trip mechanism, this breaker responds to both prolonged overloads and instantaneous fault conditions, helping you protect electrical equipment while supporting safe, reliable power distribution. Designed for 120/240VAC applications with a 22kA interrupting capacity (A.I.C.), the QNRH200 is well-suited for demanding residential service entrance installations. Its reversed handle configuration and plug-in design simplify installation in compatible load centers, while operation at 40°C and 50/60Hz makes it suitable for a wide range of standard residential electrical environments. Requiring four panel spaces, this breaker is an excellent choice for replacement projects, panel upgrades, or new installations where the specified Type QNRH breaker is required.
