CHH2125 - 125Amp Circuit Breaker

CHH2125 - 125 Amp Circuit Breaker

The CHH2125 molded case circuit breaker is designed to provide dependable circuit protection for electrical distribution systems that require a 2-pole, 125-amp breaker with a 100kA interrupting capacity at 240VAC. Built on the CHH frame platform, this breaker features a non-interchangeable trip unit, meaning the trip mechanism is factory-matched to the breaker for consistent overcurrent protection. Its molded case construction helps protect internal components from environmental conditions and mechanical wear, supporting stable operation in demanding electrical environments. Electricians, facility managers, and maintenance professionals often rely on CHH-frame breakers when maintaining or servicing existing commercial and industrial power systems that require specific frame compatibility. With ratings suited for higher fault current applications, the CHH2125 circuit breaker helps safeguard conductors and equipment by interrupting overloads and short circuits before damage occurs. Products in this class are built to last and are commonly used when a form, fit, and function replacement is needed for installed electrical infrastructure.
