EHB2100L - 100Amp Circuit Breaker

EHB2100L - 100 Amp Circuit Breaker

When you’re dealing with an older panel, the last thing you want is guesswork. The EHB2100L circuit breaker is built for exactly that situation—giving you a straightforward, form-and-fit replacement for EHB frame panelboards manufactured before 1989. No modifications, no surprises—just a breaker that fits the way it’s supposed to. This 2-pole, 100-amp breaker uses a thermal-magnetic trip mechanism to help protect your system from overloads and short circuits. With a 14k A.I.C. rating at 480VAC, it’s designed to safely interrupt fault conditions in commercial and industrial environments. The non-interchangeable trip unit keeps your original configuration intact, which is critical when you're maintaining system consistency in legacy equipment. It also comes with line and load terminals included, so you can get it installed and back in operation without unnecessary delays. Simply put, if you need a dependable replacement that aligns with your existing setup, this breaker does the job—cleanly and reliably.
