Description
The HFD3070V is a 3-pole, 70A molded case circuit breaker from Eaton's Series C F-Frame family. Built for industrial and marine environments, it provides robust thermal-magnetic protection. This panel-mount unit installs into Eaton Series C panelboards. It is replaced by the PDG23M0070VFFJ, requiring a retrofit kit for older enclosures. Rated 65 kAIC at 480VAC, it handles high fault currents. It features reverse feed capability, HACR rating, and a 50°C ambient calibration.Specifications

Product FAQs
6 answersWhat does the V suffix in the HFD3070V catalog number indicate?
The V suffix denotes that this breaker is factory-calibrated for a 50 degrees Celsius ambient temperature, rather than the standard 40 degrees Celsius calibration. This makes it suitable for high-heat industrial or marine environments.
Can I adjust the trip settings on the HFD3070V?
No, this breaker features a thermal-magnetic trip unit with fixed thermal and fixed magnetic settings. The long-time and instantaneous trip functions are factory-set and cannot be adjusted in the field.
Is the HFD3070V suitable for reverse feed applications?
Yes, standard Eaton Series C F-frame thermal-magnetic circuit breakers, including the HFD3070V, are suitable for reverse feed applications.
What is the difference between Eaton FD, HFD, and FDC breakers?
These breakers share the same physical F-frame footprint but offer different interrupting capacities. The FD is the standard rating, the HFD is the high-interrupting version, and the FDC provides the highest extra-high or current-limiting interrupting capacity.
Are the standard lugs on the HFD3070V rated for aluminum wire?
Yes, the standard load-side lugs accept 14 to 1/0 AWG wire and are dual-rated for both copper and aluminum conductors.
Will this breaker fit in an older Cutler-Hammer panelboard?
Yes, Eaton manufactures the Series C line, which is fully backwards compatible with legacy Cutler-Hammer and Westinghouse Series C panelboards, switchboards, and motor control centers.
