ED3100 - 100Amp Circuit Breaker

ED3100 - 100Amp Circuit Breaker

If you're replacing an existing breaker in an Eaton Series C electrical system, matching the original frame, ratings, and terminal configuration is one of the most important parts of the job. The Eaton ED3100 is a 100 Amp, 3-pole molded case circuit breaker designed for use in compatible Eaton Series C ED-frame equipment. It's commonly installed as a direct replacement in commercial and industrial electrical systems where maintaining the original fit, function, and electrical characteristics helps keep the installation consistent.

This breaker utilizes Eaton's T186 thermal magnetic trip unit, combining thermal protection for sustained overload conditions with instantaneous magnetic protection for short circuits. Together, these functions provide dependable circuit protection during normal operation while helping safeguard connected equipment from electrical faults.
