EHD3100 - 100Amp Circuit Breaker

EHD3100 - 100 Amp Circuit Breaker

When you’re dealing with an existing electrical system, the last thing you want is a breaker that almost fits. The Eaton EHD3100 is built for situations where compatibility matters. It’s a 100 amp, three-pole molded case circuit breaker from Eaton’s Series C line—commonly used in commercial and industrial setups—so it drops into the right applications without forcing changes to your setup.

This breaker uses a T186 trip unit, giving you consistent response to overloads and short circuits. In plain terms, it does what it’s supposed to do—protect your system and help prevent costly downtime. The F-frame design keeps the footprint manageable, which helps when you’re working inside existing panelboards or tight enclosures.

It’s also the kind of component that’s made to stay in service. Solid construction, straightforward connections, and no unnecessary complications. If you’re replacing a unit or keeping spares on hand, this is the type of breaker that keeps things simple.
