Product FAQs
8 answersWhat does the "L" suffix in the HFD2125L catalog number indicate?
The "L" indicates that the breaker comes factory-equipped with both line and load lugs. Without this suffix, the breaker would be supplied with standard terminal pads only.
Can I use the HFD2125L to replace a standard FD2125L?
Yes. The HFD2125L shares the exact same physical dimensions and mounting footprint as the standard FD2125L. The HFD version simply offers a higher interrupting capacity of 65kAIC at 480VAC compared to 35kAIC for the standard FD.
What is the difference between the HFD2125L and the FDC2125L?
Both are Series C F-frame breakers with identical physical dimensions. The difference is the interrupting rating. The HFD2125L is rated for 65kAIC at 480VAC, while the FDC2125L is the extra-high interrupting version rated for 100kAIC at 480VAC.
Is the HFD2125L suitable for reverse feeding?
Yes. Standard Eaton Series C thermal-magnetic breakers like the HFD2125L are not marked with line and load restrictions, making them suitable for reverse feed applications.
Which panelboards are compatible with the HFD2125L?
This F-frame breaker is designed for use in Eaton and Cutler-Hammer Series C panelboards, switchboards, and motor control centers. It is a unit mount breaker and will not fit in standard residential plug-on load centers.
Does this breaker provide adjustable trip settings?
No. The HFD2125L features a fixed thermal and fixed magnetic trip unit. It does not offer adjustable long-time or instantaneous settings.
Does the HFD2125L include ground fault protection?
No. This is a standard thermal-magnetic breaker providing overload and short-circuit protection. It does not include equipment ground fault or personnel ground fault protection.
Can this breaker be mounted on a DIN rail?
The HFD2125L is natively designed for unit mounting in panelboards and enclosures. It requires a specific Eaton F-frame DIN rail adapter plate if you intend to mount it on a standard 35mm DIN rail.
