CHH3175 - 175Amp Circuit Breaker

CHH3175 - 175 Amp Circuit Breaker

The CHH3175 molded case circuit breaker is designed to provide dependable overcurrent protection in electrical distribution systems that require a 175-amp, 3-pole breaker with a 100kA interrupting rating at 240VAC. Built on the CHH frame, this breaker features a non-interchangeable trip unit, meaning the trip mechanism is permanently integrated into the breaker for consistent protection characteristics. Its molded case construction helps protect internal components from environmental exposure while maintaining stable electrical performance in demanding commercial and industrial environments. The CHH3175 is commonly used as a form, fit, and functional replacement in compatible panelboards and switchboards where the CHH frame type is specified. Electrical professionals rely on breakers in this class because they are built to last and designed to maintain proper circuit protection in established power distribution systems.
