HFD3125L - 125Amp Circuit Breaker

HFD3125L - 125Amp Circuit Breaker

The Eaton HFD3125L is a 125 Amp, three-pole Series C molded case circuit breaker used in electrical systems built around the HFD F-frame platform. It’s most often selected for replacement and maintenance work where your existing equipment already calls for this breaker style, rating, and terminal configuration. Rather than changing the system layout, the HFD3125L is intended to maintain the original form, fit, and electrical characteristics when all specifications match.
