EHC3100 - 100Amp Circuit Breaker

EHC3100 - 100 Amp Circuit Breaker

When you need a circuit breaker that fits your existing setup without second-guessing specs, the EHC3100 gets straight to the point. This 3-pole, 100-amp thermal-magnetic circuit breaker is built for reliable protection in commercial and industrial systems, especially where matching the original equipment matters. It’s designed to drop into EHC frame applications with the correct form, fit, and function—no modifications, no surprises. Rated for up to 480VAC, the EHC3100 handles everyday electrical demands with consistent trip response thanks to its fixed, non-interchangeable trip unit. Whether you're dealing with overloads or short circuits, this breaker reacts the way it's supposed to—predictably and dependably. With interrupting ratings of 14k A.I.C. at 480VAC and 18k A.I.C. at 240VAC, it’s a practical choice for systems operating within those fault levels. It also comes with load terminals included, saving time during installation. Built to last and designed for 40°C environments, this breaker is a solid fit for keeping existing electrical systems running safely and efficiently.
