QJH22B090 - 90Amp Circuit Breaker

QJH22B090 - 90Amp Circuit Breaker

The QJH22B090 is a 2-pole, 90-amp molded case circuit breaker designed for use in your 120/240VAC electrical distribution systems. Built for dependable circuit protection, this Type QJH circuit breaker helps you protect electrical equipment and conductors from damage caused by overloads and short circuits while maintaining compatibility with equipment designed for this breaker series. Rated for 22kA interrupting capacity at 120/240VAC, it is well suited for commercial and industrial applications where available fault current requires a higher interrupting rating. This breaker is HACR-rated, includes load-side lugs for installation, and is designed for operation in 40°C ambient conditions. Built to last, the QJH22B090 is an excellent choice when maintaining or replacing an existing breaker in compatible electrical systems, providing the correct form, fit, and function without unnecessary modifications.
