Part of Eaton's Series C line, the FD3015V is a 3-pole, 15A molded case circuit breaker built for commercial and marine applications. It features a 50°C ambient calibration for high-temperature environments. The bolt-on unit installs into Eaton Series C panelboards and motor control centers. It replaces older Cutler-Hammer FD-frame breakers and is succeeded by the PDG23G0015TFFJ. Delivering 35 kAIC at 480VAC, it utilizes fixed thermal-magnetic trip technology and is HACR rated.
What does the V suffix indicate in the FD3015V catalog number?
The V suffix denotes that the breaker is calibrated for 50°C (122°F) high ambient temperatures. This specialized calibration is typically required for naval, marine, or heavy industrial applications where standard 40°C breakers might experience nuisance tripping.
What enclosures are compatible with the FD3015V?
This F-frame breaker is designed exclusively for Eaton and Cutler-Hammer Series C panelboards, switchboards, and motor control centers. It is not compatible with newer Series G or Power Defense enclosures.
How are the line and load connections configured on this breaker?
The FD3015V features a bolt-on line side that connects directly to the panel busbar without lugs. The load side includes standard mechanical lugs that accept 14 AWG to 1/0 AWG copper or aluminum wire.
What are the physical dimensions of the FD3015V?
As a standard 3-pole Series C F-frame breaker, it measures 6 inches in height, 4.13 inches in width, and 3.38 inches in depth.
Are the thermal and magnetic trip settings adjustable on the FD3015V?
No, this breaker is equipped with a non-interchangeable trip unit featuring fixed long-time (thermal) and fixed instantaneous (magnetic) protection. The trip curve cannot be adjusted in the field.
Will I receive an Eaton or Cutler-Hammer branded breaker?
Eaton acquired Cutler-Hammer and integrated their product lines. Depending on the manufacturing date, the FD3015V may be labeled under either brand. Both are the exact same Series C F-frame breaker and are fully interchangeable.

175amp molded case circuit breaker
The breaker we purchased was as advertised. The breaker fit perfectly. We purchased reconditioned breaker and it seems to be working properly, accordingly to the golf course maintenance team that supervises the irrigation system.
Next day shipping came quickly even though the 4th of July was coming.
I wish it came with new installations hardware but that isn’t a deal breaker.
