CH3100 - 100Amp Circuit Breaker

CH3100 - 100Amp Circuit Breaker

The CH3100 is a 100 Amp, 3-pole CH bolt-on circuit breaker used in compatible CH panelboards and switchgear. It’s built for three-phase systems where a larger load needs dedicated protection. In real-world use, this breaker usually shows up on bigger HVAC units, compressors, pumps, and motor loads running on 240V or 480V three-phase power.

When you're replacing one, it’s typically a matter of matching a few basics—CH type, 3 poles, 100 amps, bolt-on connection—so it fits and functions the same way as the original. This breaker is rated for 240VAC and 480VAC systems, with a 14kA interrupting rating at 480VAC and 65kA at 240VAC. It uses a thermal magnetic trip unit with a fixed, non-interchangeable design, and is rated for 50/60Hz operation in 40°C environments. It is also HACR rated, so it’s acceptable for HVAC applications where that listing is required.

The bolt-on design gives it a solid, direct connection inside compatible equipment. Once installed in a CH-compatible panelboard or switchgear, it handles standard protection for three-phase branch circuits carrying higher electrical loads.
