EHB3030L - 30Amp Circuit Breaker

EHB3030L - 30 Amp Circuit Breaker

When you’re maintaining an older electrical system, finding the exact breaker that fits—and works the way it should—matters. The EHB3030L circuit breaker is built specifically for that purpose. Designed for use in panelboards manufactured prior to 1989, this 30-amp, 3-pole breaker delivers the precise form and fit needed to keep your existing setup running safely and efficiently without reconfiguration. This breaker uses a thermal-magnetic trip mechanism, which means it reacts to both long-term overloads and sudden short circuits. In everyday terms, it helps prevent damage before it becomes a bigger problem. With a 14kA interrupting rating at 480VAC, it’s well-suited for many commercial and industrial applications where dependable circuit protection is essential. The included line and load terminals make installation more straightforward, especially when replacing an existing unit. Built to last and rated for 40°C environments, the EHB3030L is a practical, no-nonsense solution for keeping legacy electrical systems up and running with confidence.
