EHB3030 - 30Amp Circuit Breaker

EHB3030 - 30Amp Circuit Breaker

When you're maintaining an existing electrical system, finding the correct replacement breaker is essential. The EHB3030 is a 3-pole, 30-amp Type EHB thermal-magnetic circuit breaker designed as a form, fit, and functional replacement for compatible panelboards manufactured before 1989. By matching the original breaker's ratings and configuration, it helps preserve the integrity of your existing electrical distribution system without requiring modifications to the panel.

Whether you're servicing a manufacturing facility, commercial building, educational campus, or another property with older electrical infrastructure, selecting a breaker that matches the original equipment is one of the most important steps in maintaining system reliability.
