CHH3150H2 - 150Amp Circuit Breaker

CHH3150H2 - 150Amp Circuit Breaker

When you're replacing a breaker in an existing CHH2 panel, the main goal is usually simple—match what’s already there so the system keeps running without changes. The CHH3150H2 is a 150 amp, 3-pole molded case circuit breaker used in setups where that exact CHH2 configuration is already in place.

This breaker is built for 240VAC three-phase systems, where all three poles need to operate together. It shows up in feeder circuits, distribution panels, and equipment circuits in commercial and industrial facilities—basically anywhere power is already distributed through an established panel layout.

With a 25kA interrupting rating at 240VAC, this unit is intended for systems where the available fault current has already been accounted for in the original design. In most cases, it’s not about changing anything upstream—it’s about replacing a breaker with the same electrical characteristics so the installation stays consistent.

Like most molded case breakers used in long-running electrical systems, it’s meant for service in properly maintained equipment where matching the original part is more important than redesigning the system.
