CHH3150H2 - 150Amp Circuit Breaker

CHH3150H2 - 150 Amp Circuit Breaker

The CHH3150H2 molded case circuit breaker is designed for dependable circuit protection in electrical distribution systems that require a 150-amp, 3-pole breaker with a 25k A.I.C. 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 predictable protection. Molded case breakers like the CHH3150H2 are commonly used in commercial and industrial panels where maintaining compatibility with existing electrical infrastructure is important. With its solid construction and straightforward installation within compatible panelboards and switchgear, this unit helps protect wiring and equipment from overloads and short circuits. These breakers were built to last and continue to serve as dependable replacements for maintaining legacy power distribution systems.
