EHB1030L - 30Amp Circuit Breaker

EHB1030L - 30Amp Circuit Breaker

If you're maintaining an older electrical panel, finding the correct replacement breaker can make all the difference. The EHB1030L is a 1-pole, 30 Amp thermal-magnetic molded-case circuit breaker designed for compatible EHB series electrical panels manufactured before 1989. Instead of changing the panel or adopting newer components, this breaker is intended to match the original form, fit, and function, helping to keep your existing electrical system configured as it was designed.

The breaker uses a thermal-magnetic trip mechanism, which responds to overloads over time while also reacting quickly to short-circuit conditions. It features a 14kA interrupting rating at 277VAC, a non-interchangeable trip unit, and comes with both line and load terminals, making it suitable for compatible replacement applications.

Where It Works Best

• The EHB1030L is commonly used in commercial, industrial, and institutional facilities that continue to operate equipment designed for EHB series circuit breakers. It's a good fit for lighting panels, branch circuits, distribution panels, and other legacy electrical systems requiring a 1-pole, 30 Amp thermal-magnetic breaker with a 14 kA interrupting rating at 277 VAC.
• If your goal is to keep an existing panel in service without changing its original design, using a breaker with the correct specifications is essential. The EHB1030L provides the form, fit, and functional compatibility needed for designated applications, helping maintain the intended operation of compatible electrical equipment.
