HFD3125 - 125Amp Circuit Breaker
The Eaton HFD3125 is a 125 Amp, three-pole Series C molded case circuit breaker used in electrical systems built around the HFD breaker family. Most often, you’ll see it used for replacement work where the existing equipment already calls for the same breaker style and electrical ratings. Rather than changing the original setup, the HFD3125 lets you maintain the same basic form, fit, and function when the specifications match.
