FD3020L - 20Amp Circuit Breaker

FD3020L - 20Amp Circuit Breaker

Electrical rooms have a way of reminding you that appearances can be deceiving. It's not unusual to find two breakers that look almost identical sitting side by side, yet one small difference in the trip unit or interrupting rating can make all the difference during installation. That's why experienced maintenance teams spend just as much time confirming the catalog number and electrical ratings as they do pulling the old breaker out of the panel.

The Eaton FD3020L Series C molded case circuit breaker is a 20 Amp, three-pole replacement breaker for compatible F-frame Series C applications. It uses a T186 thermal magnetic trip unit to respond to overloads and short circuits while maintaining the protection the original equipment was built around.
