EH14030 - 30 Amp Circuit Breaker

EH14030 - 30 Amp Circuit Breaker

Finding the right replacement circuit breaker is about more than matching the amperage—it’s about maintaining compatibility with your existing electrical system. The EH14030 is a 1-pole, 30-amp plug-on thermal-magnetic circuit breaker designed as a form, fit, and function replacement for compatible Type EH-4 panelboards. It helps protect branch circuits by responding to both prolonged overloads and sudden short-circuit conditions, providing the protection your electrical system was originally designed to provide.

With a 14 kA interrupting capacity at 277 VAC, the EH14030 is intended for use in compatible commercial, industrial, and institutional electrical systems where these ratings are required. Its plug-on design makes installation straightforward in compatible equipment, helping simplify routine maintenance and repairs. Whether you're replacing an existing breaker during scheduled service or restoring a system to proper working order, choosing the correct breaker type and electrical ratings helps ensure the best fit for your application.
