EDB3100 - 100Amp Circuit Breaker

EDB3100 - 100 Amp Circuit Breaker

The Eaton EDB3100 is a straightforward 100-amp, 3-pole circuit breaker used in a wide range of commercial and industrial setups. It’s part of Eaton’s Series C line, which a lot of electricians and maintenance teams already know and trust, so there’s no guesswork when it comes to fit or performance. This breaker is built to handle up to 240V AC and 125V DC, and it uses a T186 trip unit to cut power when there’s an overload or fault. Nothing fancy—just reliable protection that does its job when it needs to. It’s also compact enough to fit into tighter panel spaces, which makes it a practical choice for both replacements and new installs.
