CHH3125H2 - 125Amp Circuit Breaker

CHH3125H2 - 125 Amp Circuit Breaker

The CHH3125H2 molded case circuit breaker is designed to provide dependable circuit protection for electrical distribution systems that require a 125-amp, 3-pole breaker within a CHH2 frame configuration. Built for form, fit, and functional compatibility with existing equipment, this breaker helps maintain safe electrical operation by interrupting overloads and short circuits before damage can occur. Its 25kA interrupting capacity at 240VAC supports use in commercial and industrial power systems where reliable fault interruption is required. The non-interchangeable trip unit ensures consistent trip characteristics for the life of the breaker, making it suitable for installations where stable, fixed protection settings are necessary. With a molded case design built to last, the CHH3125H2 is commonly used in distribution panels and equipment where maintaining compatibility with existing CHH2-frame systems is essential.
