CHH2175H2 - 175Amp Circuit Breaker

CHH2175H2 - 175 Amp Circuit Breaker

The CHH2175H2 molded case circuit breaker is a 2-pole, 175-amp breaker designed to provide dependable overcurrent protection in electrical distribution systems operating at up to 240VAC. Built on the CHH2 frame platform, this breaker features a non-interchangeable trip unit, meaning the trip mechanism is permanently matched to the breaker for consistent protection characteristics. With an interrupting rating of 25kA at 240VAC, the CHH2175H2 is well suited for systems where reliable short-circuit interruption is required. Molded case construction helps protect internal components while supporting stable operation in demanding electrical environments. For maintenance teams and facility operators maintaining existing electrical infrastructure, this breaker provides the proper form, fit, and functional replacement for compatible installations. These units were engineered for long service life and are built to last, helping maintain system protection in commercial and industrial applications.
