Description
Engineered for industrial power distribution, the Eaton HFD2070L is a two-pole, 70A molded case circuit breaker rated for 65 kAIC at 480VAC. The "L" suffix indicates it comes equipped with line and load lugs for unit-mount applications. This F-Frame breaker installs into Eaton Pow-R-Line panelboards supporting cable-in/cable-out configurations. The Power Defense PDG22M0070TFFJ serves as the recommended replacement for this footprint. Features include a HACR rating and reverse feed capability.Specifications

Product FAQs
8 answersHow does the HFD2070L differ from standard FD2070L or FDC2070L breakers?
The HFD prefix indicates a high-interrupting capacity version of the Series C F-Frame. While a standard FD breaker is rated for 35kA at 480VAC, the HFD2070L provides 65kA at 480VAC. The FDC version offers an even higher 100kA at 480VAC. All three share the exact same physical dimensions and mounting footprint.
What does the 'L' suffix in the HFD2070L catalog number signify?
The 'L' suffix indicates that the breaker comes with factory-installed line and load terminals. These standard lugs are designed to accept 14 to 1/0 AWG copper or aluminum wire.
In which types of equipment can I install the HFD2070L?
This unit-mount F-Frame breaker is designed for use in Eaton Series C panelboards, Pow-R-Line panelboards, switchboards, and motor control centers. It is designed for bolt-on or standalone unit mounting rather than plug-on load center applications.
Can I use the Eaton HFD2070L to replace an older Westinghouse or Cutler-Hammer HFD2070L?
Yes. Eaton acquired the Cutler-Hammer and Westinghouse molded case circuit breaker lines. The modern Eaton Series C HFD2070L is an exact drop-in replacement for legacy Westinghouse and Cutler-Hammer models bearing the same catalog number.
Are internal accessories like shunt trips or auxiliary switches compatible with this 2-pole breaker?
Yes, Eaton Series C F-Frame breakers support field-installable internal accessories. These accessories, such as shunt trips, bell alarms, and auxiliary switches, are typically mounted in the right or left pole cavities behind the front cover.
Is the HFD2070L suitable for DC voltage applications?
Yes, this thermal-magnetic breaker is rated for up to 250VDC with an interrupting capacity of 22kA. When applying it in DC circuits, ensure the wiring configuration complies with Eaton guidelines for DC switching, which may require wiring poles in series depending on the system voltage.
Does this breaker require a specific mounting hardware kit?
As a unit-mount (feed-thru) breaker, it typically requires a base mounting hardware kit if it is being installed on a backpan or in a motor control center bucket. The exact hardware kit depends on the specific enclosure and panelboard chassis type.
What are the recommended maintenance procedures for this thermal-magnetic breaker?
Following NEMA AB 4 guidelines, you should periodically exercise the breaker by manually toggling it on and off to keep the mechanical linkages free. Additionally, verify that the line and load lug connections remain torqued to the manufacturer specifications printed on the breaker faceplate.
