CHH3175H4 - 175Amp Circuit Breaker

CHH3175H4 - 175 Amp Circuit Breaker

The CHH3175H4 molded case circuit breaker is designed for use in electrical distribution systems that require dependable overcurrent protection and compatibility with existing CHH4 frame equipment. Rated at 175 amps with a 42kA interrupting capacity at 240VAC, this 3-pole breaker helps safeguard electrical circuits by interrupting overloads and short circuits before they can damage connected equipment or wiring. Built with a non-interchangeable trip unit, the breaker provides consistent protection aligned with its factory-set rating. Its construction reflects the long service life expected in molded case breakers used in commercial and industrial installations, making it a practical form-fit-function replacement for compatible legacy systems where maintaining the original configuration is important.
