Product FAQs
6 answersIs the Eaton HFD3125L interchangeable with older Westinghouse or Cutler-Hammer HFD breakers?
Yes. Eaton acquired the Cutler-Hammer and Westinghouse breaker lines. The Series C F-frame design remains consistent, making the HFD3125L a direct drop-in replacement for legacy models with the exact same catalog number.
What does the L suffix indicate in the HFD3125L catalog number?
The L indicates that the breaker comes factory-equipped with both line and load lugs. These standard terminals are designed to accept 4 AWG to 4/0 AWG copper or aluminum wire.
How does the HFD3125L differ from a standard FD3125L breaker?
The HFD prefix designates a high-interrupting capacity breaker. While a standard FD breaker is rated for 35kAIC at 480VAC, the HFD3125L provides a higher 65kAIC rating at 480VAC for systems requiring greater fault current protection.
Can this breaker be installed in a standard residential load center?
No. The HFD3125L is a unit-mount, feed-thru molded case circuit breaker designed for Eaton Series C panelboards, motor control centers, switchboards, and industrial enclosures. It is not compatible with standard residential plug-on or bolt-on load centers.
Is the HFD3125L suitable for direct current (DC) systems?
Yes, this thermal magnetic breaker is rated for use in DC applications up to 250VDC, providing an interrupting capacity of 22kAIC for direct current circuits.
Are the trip settings adjustable on this breaker?
No. The HFD3125L features a fixed thermal and fixed magnetic trip unit. If your application requires adjustable trip settings, you will need to specify a breaker with an electronic trip unit.
