FD3100 - 100Amp Circuit Breaker

FD3100 - 100Amp Circuit Breaker

When your 100 amp breaker needs to be replaced, finding the right part is about more than matching the number on the label. The replacement needs to fit the existing equipment and match the electrical details that matter in the field, including the frame, trip unit, voltage rating, terminals, and interrupting capacity. Getting those details right before installation can save time and prevent unnecessary troubleshooting later.

The Eaton FD3100 is a 100 Amp, three-pole molded case circuit breaker from the Series C family with an F-frame design for compatible applications. It uses a T186 thermal magnetic trip unit to respond to overloads and short circuits while fitting the protection requirements of the original electrical system. Rated for 600 VAC and 250 VDC, this breaker is designed for 50/60 Hz systems and includes a load-side terminal configuration.
