FD2100 - 100Amp Circuit Breaker

FD2100 - 100Amp Circuit Breaker

Not every breaker replacement is part of a scheduled shutdown. Sometimes a breaker refuses to reset after years of dependable service. Other times it's pulled during an inspection because it's showing signs of wear before it causes an unexpected outage. In either case, the job usually comes down to finding the right replacement the first time. A breaker that looks close isn't always the same once it's in the panel, and small differences can quickly turn a simple replacement into extra downtime.

Whether you're replacing a failed breaker during an emergency call or stocking a spare for future maintenance, having the correct part on hand can save valuable time once the panel cover comes off.

Material Compliance and Certifications

The Eaton FD2100 is UL Listed and manufactured to Eaton's published specifications. Before replacing a breaker, it's always worth confirming the frame size, amperage rating, pole configuration, voltage rating, interrupting capacity, and trip unit match the original device. A few minutes spent checking compatibility before the work begins is often easier than discovering a mismatch after the breaker has already been removed. Installation should be completed by qualified personnel and in accordance with applicable electrical codes.

Where It Works Best

The FD2100 is a practical replacement for compatible Eaton Series C F-frame breakers installed in commercial buildings, manufacturing facilities, schools, hospitals, office buildings, and other industrial or institutional electrical distribution systems. It's a good choice when restoring service after a breaker failure, replacing aging equipment during preventive maintenance, or keeping a properly matched spare available for critical systems.
