QJ22B175 - 175Amp Circuit Breaker

QJ22B175 - 175Amp Circuit Breaker

The QJ22B175 is a 2-pole, 175-amp molded case circuit breaker designed for use in your compatible electrical distribution systems requiring 120/240VAC operation with a 10kA interrupting capacity (A.I.C.). Built for dependable circuit protection, this Type QJ breaker is intended as a form, fit, and functional replacement in existing installations where matching ratings and compatibility are required. Rated for operation in 40°C ambient environments and HACR applications, it helps you protect electrical systems by interrupting overloads and short circuits while supporting safe operation of connected equipment. The breaker also includes load-side lugs, helping you to simplify installation where compatible. Built to last, the QJ22B175 is well-suited for commercial and industrial applications that require a 175-amp, 2-pole molded case circuit breaker with the appropriate voltage and interrupting ratings.

Where It Works Best

• The QJ22B175 is designed for use in compatible commercial, industrial, and institutional electrical distribution systems requiring a 2-pole, 175-amp Type QJ molded case circuit breaker. It is an appropriate choice when replacing an existing breaker with the same electrical ratings, pole configuration, and compatible form and fit. Typical applications include panelboards, distribution equipment, and HVAC-related installations where a HACR-rated breaker is specified and a 120/240VAC, 10kA interrupting capacity meets system requirements.
