EHB24020 - 20 Amp Circuit Breaker

EHB24020 - 20 Amp Circuit Breaker

When you’re working with an existing electrical system, the last thing you want is guesswork. The EHB24020 circuit breaker gives you a straightforward, exact-fit solution for EHB-4 frame panelboards—no modifications, no surprises. Designed as a 2-pole, 20-amp breaker, it’s built to handle everyday protection needs in commercial and industrial setups, helping safeguard circuits from overloads and short circuits without complicating your install.

What makes this breaker especially practical is its bolt-on design, which creates a secure, stable connection directly to the panelboard. That means less movement, better contact, and consistent operation over time. With interrupting ratings of 14kA at 480VAC and 65kA at 240VAC, it’s suited for environments where dependable fault protection is essential. Whether you’re replacing an existing unit or maintaining a legacy system, this breaker keeps things running the way they were designed to—simple, reliable, and built to last.
