FD3040L - 40Amp Circuit Breaker Description
FD3040L - 40Amp Circuit Breaker
When your breaker needs to be replaced, finding one that matches the existing equipment is the part that matters most. The amp rating is only the starting point. Frame size, trip unit, voltage rating, terminal setup, and interrupting capacity all need to match before the replacement goes into service. A few minutes spent checking those details can save a lot of time once the panel is open.
The Eaton FD3040L is a 40 Amp, three-pole molded case circuit breaker from the Series C family, built with an F-frame design for compatible electrical distribution systems. It uses a T186 thermal magnetic trip unit to respond to overloads and short-circuit conditions while matching the protection requirements of the original equipment.
