CHH2150H4 - 150Amp Circuit Breaker

CHH2150H4 - 150 Amp Circuit Breaker

The CHH2150H4 molded case circuit breaker is designed to provide dependable overcurrent protection in electrical distribution systems that require a 150-amp, 2-pole breaker with a 42kA interrupting rating at 240VAC. Built on the CHH4 frame, this unit features a non-interchangeable trip unit, meaning the trip mechanism is factory-configured as part of the breaker assembly to maintain consistent protection characteristics. This configuration helps ensure reliable operation for circuits operating within its intended ratings. Molded case breakers like the CHH2150H4 are commonly used in commercial and industrial power distribution equipment where maintaining compatibility with existing panelboards and switchgear is important. Its solid construction and tested design reflect equipment built to last, providing dependable protection against overloads and short circuits while maintaining form, fit, and functional compatibility with systems designed for the CHH4 frame.
