EHB24030 - 30 Amp Circuit Breaker

EHB24030 - 30 Amp Circuit Breaker

If you’re maintaining or replacing a breaker in an existing panelboard, the EHB24030 gives you a straightforward, no-guesswork solution. This 30-amp, 2-pole E-Frame miniature circuit breaker is designed to fit and function exactly where it’s needed—especially in NF panelboards commonly found in commercial and industrial setups. It handles both overloads and short circuits through its thermal-magnetic trip mechanism, meaning it reacts appropriately whether the issue builds over time or happens instantly.

Contractors and facility managers often turn to this model for lighting and HVAC circuits, thanks to its HID and HACR ratings. It’s built to last, and more importantly, built to match the form and fit requirements of existing systems—so you’re not dealing with compatibility headaches or unnecessary modifications. With solid interrupting capacity and a clear trip indicator, it helps keep your electrical system protected while making troubleshooting faster and easier.
