EHB3030 - 30Amp Circuit Breaker

EHB3030 - 30 Amp Circuit Breaker

If you're working with an older electrical panel, you already know how important it is to find a breaker that actually fits—and functions the way the original system was designed. The EHB3030 circuit breaker is built for exactly that purpose. Designed for panelboards manufactured before 1989, this 30-amp, 3-pole breaker gives you the right combination of form, fit, and function without the guesswork. At its core, this breaker uses a thermal-magnetic trip mechanism, which means it responds to both prolonged overloads and sudden short circuits. That kind of protection is essential in keeping your system operating safely day in and day out. With a 14kA interrupting rating at 480VAC and a 40°C operating standard, it’s well-suited for a wide range of commercial and industrial applications where older equipment is still in service. It also comes with load terminals included, helping streamline installation and reduce extra steps on the job. Simply put, this is a straightforward, dependable solution for maintaining legacy systems—built to last and designed to match what’s already in place.
