Rated for 65 kAIC at 480V, this three-pole molded case breaker handles severe electrical faults in commercial power systems. It installs into Eaton Series C panelboards and switchboards for reliable branch circuit defense. The F-Frame device utilizes a fixed thermal-magnetic trip mechanism for accurate LI protection. Equipped with standard line and load terminals, it accommodates 14 to 1/0 AWG wire and offers an upgrade path to the modern Power Defense series.

Product FAQs
8 answers
What equipment is the HFD3080LH12 designed to fit?
This Series C, F-Frame breaker installs into Eaton and legacy Cutler-Hammer panelboards, switchboards, and motor control centers. It is not compatible with standard residential load centers.
Are terminal lugs included with this breaker?
Yes, the L in the catalog number indicates that factory-installed line and load lugs are included. They accept 14 AWG to 1/0 AWG aluminum or copper conductors.
How is the HFD3080LH12 mounted in a panel?
It is a unit mount, feed-thru breaker. This means it bolts directly to the equipment chassis or mounting pan and requires wire connections on both the line and load sides, rather than plugging into a busbar.
Can this breaker be used in DC circuits?
Yes, the HFD3080LH12 is rated for 250VDC applications with a 22kAIC interrupting rating, making it suitable for specific industrial DC control panels or battery systems.
Does this breaker offer adjustable trip settings?
No, it features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous protection parameters are factory set for 80 amps and cannot be modified in the field.
What does the H in the HFD prefix signify?
In the Eaton Series C family, the H indicates a high-interrupting capacity frame. The HFD3080LH12 is rated for 65kAIC at 480VAC, which provides a higher fault current rating than standard FD breakers.
Is there a difference between the Eaton and Cutler-Hammer versions of the HFD3080LH12?
No, Eaton acquired Cutler-Hammer and continues to manufacture these Series C breakers under the Eaton name. The physical dimensions, mounting, and performance specifications are identical.
What type of protection does the thermal-magnetic trip unit provide?
The thermal component responds to prolonged overloads by heating a bimetallic strip, while the magnetic component responds immediately to severe short circuits. This combination provides comprehensive branch circuit defense.
