Product FAQs

8 answers
What panelboards and equipment are compatible with the HFD2045L?

This breaker is designed for use in Eaton Series C panelboards, Pow-R-Line panelboards, switchboards, and motor control centers.

Can I use the Eaton HFD2045L to replace an older Westinghouse or Cutler-Hammer breaker?

Yes. Eaton acquired Westinghouse's distribution equipment division and Cutler-Hammer. The Eaton HFD2045L is a direct, backwards-compatible replacement for older Westinghouse and Cutler-Hammer breakers with the exact same catalog number.

Is this a plug-on or bolt-on circuit breaker?

The HFD2045L is a unit-mount, feed-thru circuit breaker. It does not use a plug-on or bolt-on connection to a panelboard bus.

What is the difference between FD, HFD, and FDC breakers?

These are all Eaton Series C F-frame breakers, but they have different interrupting capacities. The HFD is the high-interrupting tier, offering 65kAIC at 480VAC, while the FD is standard and the FDC is extra-high interrupting.

Can the HFD2045L be used in DC electrical systems?

Yes, this thermal-magnetic breaker is rated for DC applications up to 250VDC with a maximum interrupting rating of 22kAIC.

What does the L at the end of the HFD2045L catalog number mean?

The L suffix indicates that the circuit breaker comes factory-equipped with line and load terminal lugs.

What size wire does the HFD2045L accept?

The included lugs accept copper or aluminum wire ranging from 14 AWG to 1/0 AWG.

Are the trip settings on this breaker adjustable?

No. The HFD2045L features fixed thermal and fixed magnetic trip functions (Long-Time and Instantaneous) and cannot be adjusted in the field.
