Description
High-temperature environments require specialized protection, making this 50°C calibrated 100-amp breaker ideal for marine and heavy industrial facilities. The three-pole F-Frame device mounts into Eaton Series C panelboards and motor control centers. It provides thermal-magnetic trip functions with a 65kAIC rating at 480VAC. For modern upgrades, Eaton recommends transitioning to the Power Defense PDG23M0100VFFL, though this exact replacement maintains original system compliance.Specifications

Product FAQs
7 answersWhat is the difference between the Eaton FD and HFD circuit breakers?
Both are Series C F-frame breakers with identical physical dimensions, but the HFD is the high-interrupting capacity version. The HFD3100V offers a 65kAIC rating at 480V, whereas the standard FD frame has a lower interrupting capacity.
Which panelboards and enclosures are compatible with the HFD3100V?
This F-frame breaker is designed to bolt directly into Eaton and Cutler-Hammer Series C panelboards, switchboards, and motor control centers.
What does the V in the HFD3100V catalog number signify?
The V suffix indicates that the thermal-magnetic trip unit is calibrated for a 50 degrees Celsius (122 degrees Fahrenheit) ambient temperature, rather than the standard 40 degrees Celsius calibration.
Can the HFD3100V be used in direct current (DC) systems?
Yes, this breaker is rated for DC applications and provides up to 22kA of interrupting capacity at 250VDC.
Does the HFD3100V come with both line and load lugs?
No, this specific configuration features a bolt-on connection for the line side and includes standard lugs on the load side only.
What wire sizes do the load side lugs on the HFD3100V accept?
The standard load lugs accept copper or aluminum wire ranging from 14 AWG to 1/0 AWG.
Will the Eaton HFD3100V replace older Cutler-Hammer or Westinghouse HFD breakers?
Yes, Eaton acquired the Westinghouse distribution equipment division. Current Series C F-frame breakers are direct, backward-compatible replacements for legacy Cutler-Hammer and Westinghouse models with the same frame and specifications.
