EDB3175 - 175Amp Circuit Breaker

EDB3175 - 175 Amp Circuit Breaker

If you're working with a three-phase system and need dependable protection without overcomplicating the setup, the Eaton EDB3175 is a solid choice. This 175-amp molded case circuit breaker from Eaton’s Series C line is built to handle everyday demands in commercial and industrial environments where downtime isn’t an option. It uses a T186 trip unit, which reacts quickly to overloads and short circuits—helping protect both your equipment and your bottom line. What stands out here is the balance between size and capability. The ED frame keeps things compact, so you’re not fighting for space inside your panel, but you’re still getting a breaker rated for 22 kAIC at 240 Vac. That means it’s ready to interrupt significant fault currents when necessary. It also supports 125 Vdc applications, giving you more flexibility depending on your setup. Whether you're replacing an existing breaker or setting up a new system, this model fits in without hassle and performs exactly how you'd expect from Eaton hardware.
