Product FAQs

6 answers
What panelboards are compatible with the HFD2045 circuit breaker?

This F-frame breaker is designed for use in Eaton Series C panelboards and switchboards. It requires a bolt-on connection and is not compatible with standard plug-on load centers like the BR or CH series.

What wire sizes are accepted by the terminals on the HFD2045?

The factory-installed lugs accept copper or aluminum (Cu/Al) conductors ranging from 14 AWG to 1/0 AWG. Always torque the terminals to the manufacturer specifications printed on the breaker label before energizing.

What is the difference between an FD and an HFD circuit breaker?

The HFD series is the high-interrupting capacity version of the standard FD frame. While standard FD breakers typically have a 35kAIC rating at 480VAC, the HFD2045 provides a 65kAIC rating at 480VAC for systems with higher available fault currents.

Is the HFD2045 rated for direct current (DC) applications?

Yes, this thermal-magnetic breaker is rated for up to 250VDC with an interrupting capacity of 22kAIC. It is suitable for both AC and DC power distribution systems.

How does the trip unit function on the HFD2045?

It features a non-interchangeable thermal-magnetic trip unit with fixed thermal and fixed magnetic settings. This provides standard LI (Long-Time and Instantaneous) protection against overloads and short circuits.

Can the Eaton HFD2045 replace older Westinghouse or Cutler-Hammer models?

Yes, Eaton acquired the Cutler-Hammer and Westinghouse distribution equipment lines. The HFD2045 is a direct replacement for legacy Cutler-Hammer and Westinghouse Series C HFD breakers with the exact same catalog number.
