EDB3125 - 125Amp Circuit Breaker

EDB3125 - 125 Amp Circuit Breaker

If you're maintaining or replacing components in an existing electrical system, the Eaton EDB3125 is built to match the job without guesswork. This 125-amp, three-pole molded case circuit breaker is part of the Series C family, making it a practical choice when you need something that fits correctly and works within established equipment. It handles up to 240 Vac and 125 Vdc applications and is designed to trip reliably under overload or short circuit conditions using its T186 trip unit. With a 22 kAIC interrupt rating, it provides the level of protection typically required in commercial and industrial distribution setups. Its size also makes it easier to work into panels where space is limited.

Where It Works Best

• You’ll typically see the EDB3125 used in commercial buildings, light industrial facilities, and similar environments where existing panelboards or distribution systems are already set up for Series C breakers. It’s a practical option for maintenance teams and electricians who need a like-for-like replacement that installs cleanly and keeps the system operating as intended—without reworking the setup.
