CHB3100 - 100Amp Circuit Breaker

CHB3100 - 100Amp Circuit Breaker

If you’re working on an Eaton CH Loadcenter and need a dependable 3-pole breaker replacement, the Eaton CHB3100 is built to fit right into that role without complications. Rated at 100 amps and 240 volts, this thermal magnetic circuit breaker is designed to protect electrical circuits from overloads and short circuits while maintaining proper coordination across all three poles. It’s commonly used in systems where a three-phase or multi-wire setup needs all poles to disconnect together.

Whether you're replacing an existing unit or maintaining an older system, the CHB3100 helps keep things operating within the original design intent of the panel.

Inside, the thermal magnetic mechanism does the heavy lifting—responding to long-term overload conditions with thermal protection and reacting quickly to short-circuit events through magnetic trip action. That balance makes it a practical choice for protecting wiring and connected equipment in everyday electrical distribution setups.
