FD3125L - 125Amp Circuit Breaker Description
FD3125L - 125Amp Circuit Breaker
Finding the right breaker replacement is not always just about matching the amperage. A 125 amp breaker may look like the correct choice, but the frame, trip unit, voltage rating, terminal setup, and interrupting capacity still need to match the equipment already installed. Those details are what make the difference between a straightforward replacement and an unexpected compatibility issue.
The Eaton FD3125L is a 125 Amp, three-pole molded case circuit breaker from the Series C family, built with an F-frame design for your compatible electrical distribution applications. It uses a T186 thermal magnetic trip unit to respond to overloads and short circuits while following the protection requirements of the original system. Rated for 600 VAC and 250 VDC, this breaker is designed for 50/60 Hz operation and includes line and load terminals.
