EH24030 - 30 Amp Circuit Breaker

EH24030 - 30 Amp Circuit Breaker

If you’re maintaining or servicing an existing electrical system, finding the right breaker isn’t about bells and whistles—it’s about getting the exact fit, rating, and function you can rely on. The EH24030 circuit breaker delivers just that. Built as a 2-pole, 30-amp plug-on thermal magnetic breaker, it’s designed to match EH-4 frame panelboards and keep your system operating the way it was intended. This breaker combines thermal and magnetic trip protection, meaning it reacts to both prolonged overloads and sudden short circuits. That kind of responsiveness helps protect wiring and equipment without unnecessary complications. With a 14k A.I.C. rating at 480VAC, it’s suited for environments where dependable interruption capacity matters. And because it’s a plug-on design, installation is straightforward when working within compatible setups. Simply put, this is a practical, no-nonsense solution for keeping your electrical distribution system in working order—especially when compatibility is non-negotiable.
