CHH2125H2 - 125Amp Circuit Breaker

CHH2125H2 - 125 Amp Circuit Breaker

The CHH2125H2 molded case circuit breaker is designed to provide dependable circuit protection in electrical distribution systems that require a 125-amp, 2-pole breaker with a 25kA interrupting rating at 240VAC. Built on the CHH2 frame, this breaker features a non-interchangeable trip unit, meaning the trip mechanism is permanently matched to the breaker for consistent operation and reliable protection. Units like the CHH2125H2 are commonly used in commercial and industrial panelboards where maintaining compatibility with existing equipment is important. Molded case circuit breakers of this type are built to last and are designed to help protect conductors and connected equipment from damage caused by overloads and short circuits. With its defined amperage rating, compact form factor, and straightforward installation within compatible systems, the CHH2125H2 serves as a practical replacement option when maintaining or servicing legacy electrical distribution equipment.
