EHD3070 - 70Amp Circuit Breaker

EHD3070 - 70 Amp Circuit Breaker

If you're working on an existing electrical system and need a breaker that fits without complications, the Eaton EHD3070 is a solid, no-nonsense option. This 70-amp, three-pole molded case circuit breaker is part of Eaton's Series C line, which means it's commonly found in many commercial and industrial setups already in service. It's designed to handle everyday circuit protection—overloads and short circuits—without requiring you to rethink your panel or layout. The F-frame size and T186 trip unit make it a practical match for systems originally built around this breaker style. In other words, it consistently does the job it was built for.
