EHC3030 - 30Amp Circuit Breaker

EHC3030 - 30 Amp Circuit Breaker

If you’re working on an existing panel and need a breaker that fits exactly the way it should, the EHC3030 keeps things simple. No guesswork, no modifications. This 30 amp, 3 pole circuit breaker is built specifically for EHC frame systems, making it a reliable match when maintaining or restoring original electrical setups. It uses a thermal-magnetic trip mechanism, which means it reacts appropriately to both long-term overloads and sudden short circuits—just like the system was designed to handle. Rated for up to 480VAC, it’s a practical solution for commercial and industrial environments where consistency matters more than anything else. And because time on the job matters, this unit comes with load terminals included—helping you get it installed and back in operation without unnecessary delays. It’s straightforward, dependable, and built to last in the environments it was made for.
