EHB2100 - 100Amp Circuit Breaker

EHB2100 - 100 Amp Circuit Breaker

When you’re dealing with an older panel, the last thing you want is a breaker that almost fits. The EHB2100 is made for those exact situations—designed specifically for EHB frame panelboards manufactured before 1989, so you can replace what’s there without second-guessing compatibility. This 2-pole, 100 amp thermal-magnetic circuit breaker delivers straightforward protection against overloads and short circuits, using a fixed trip unit that keeps operation consistent over time. With a 14k A.I.C. rating at 480VAC, it’s well-suited for typical commercial and industrial applications where dependable interruption matters. It’s also rated for 40°C environments, which covers most standard operating conditions you’ll run into. Installation is simple thanks to included load terminals—no extra steps, no surprises. If your goal is to keep an existing system running the way it was designed, the EHB2100 does exactly that. No modifications, no workarounds—just the right fit.
