FD2045L - 45Amp Circuit Breaker

FD2045L - 45Amp Circuit Breaker

Breaker replacements usually aren't planned. A production line shuts down, a facility loses power to a panel, or a routine inspection uncovers a breaker that's reached the end of its service life. That's when having the correct replacement matters. Matching the original breaker isn't simply about the amp rating—it also means matching the frame, poles, voltage ratings, and trip characteristics so everything fits and functions the way the system was originally built.

The Eaton FD2045L is a 45 Amp, 2-pole Series C molded case circuit breaker built for those situations. It uses Eaton's F-frame design and a T186 thermal magnetic trip unit, helping protect your electrical circuits from overloads and short circuits while maintaining the original form, fit, and function of compatible equipment.

Before replacing an existing breaker, confirm compatibility with the installed equipment, including the frame type, amperage, voltage, interrupting rating, trip unit, and terminal configuration.

Where It Works Best

The FD2045L is commonly installed in commercial buildings, industrial facilities, manufacturing plants, schools, healthcare facilities, and other locations that continue to rely on Eaton Series C distribution equipment. It's a good choice when replacing an existing FD2045L during scheduled maintenance, troubleshooting an electrical issue, or stocking a spare for critical equipment.
