Product FAQs

7 answers
What enclosures and panelboards can the HFD3100 be installed in?

This 3-pole F-Frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers.

What does the LI trip function mean on this breaker?

The LI designation indicates that the thermal-magnetic trip unit provides Long-Time thermal protection against sustained overloads and Instantaneous magnetic protection against short circuits. Both trip settings on this breaker are fixed.

Is the HFD3100 circuit breaker suitable for reverse-feed applications?

Yes, like all standard Eaton Series C F-Frame circuit breakers, the HFD3100 is fully reverse-feed capable.

Is this circuit breaker HACR rated?

Yes, this Eaton Series C F-Frame molded case circuit breaker carries an HACR rating, making it suitable for group motor applications in heating, air conditioning, and refrigeration equipment.

Can I use this to replace a Westinghouse or Cutler-Hammer HFD3100?

Yes. Eaton acquired the Cutler-Hammer and Westinghouse circuit breaker lines. A modern Eaton HFD3100 is a direct, drop-in replacement for older Cutler-Hammer or Westinghouse breakers with the exact same catalog number.

What is the difference between the Eaton FD3100 and the HFD3100?

The HFD3100 is the high-interrupting version of the standard FD3100. While they share the same physical dimensions and 100A rating, the HFD3100 provides a higher interrupting capacity (65 kAIC vs. 35 kAIC at 480VAC) for environments with higher available fault currents.

What is the difference between the HFD3100 and the FDC3100?

Both are 100A, 3-pole Series C F-Frame breakers, but the FDC3100 has an even higher interrupting capacity (100 kAIC at 480VAC) compared to the HFD3100 (65 kAIC at 480VAC).
