Product FAQs
8 answersCan the HFD2020 be installed in standard residential load centers?
No. The HFD2020 is a Series C F-frame molded case circuit breaker designed for commercial and industrial applications. It is compatible with Eaton Series C panelboards, switchboards, and motor control centers, not standard BR or CH residential load centers.
What is the difference between the HFD2020 and the standard FD2020?
The HFD2020 is the high-interrupting capacity version of the Series C F-frame. It provides a 65kAIC rating at 480VAC, whereas the standard FD2020 offers a lower 35kAIC rating at the same voltage.
Is the Eaton HFD2020 a direct replacement for legacy Westinghouse HFD breakers?
Yes. Eaton acquired the Westinghouse distribution equipment division. The current Eaton or Cutler-Hammer HFD2020 serves as a direct, drop-in replacement for older Westinghouse HFD2020 breakers.
What wire sizes are accepted by the standard lugs on this breaker?
The factory-installed lugs accommodate wire sizes from 14 AWG up to 1/0 AWG. The terminals are rated for both copper (Cu) and aluminum (Al) conductors.
Can the HFD2020 be utilized in DC voltage systems?
Yes, this thermal-magnetic breaker is rated for DC applications up to 250VDC, providing an interrupting capacity of 22kAIC for DC control or distribution circuits.
Are the thermal and magnetic trip settings adjustable on the HFD2020?
No. This breaker features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous (LI) protection but does not allow for field adjustments of the trip curve.
Does this breaker require a specific mounting hardware kit?
The HFD2020 is a bolt-on breaker that mounts directly to the chassis of compatible Series C panelboards and switchboards. Depending on the specific enclosure, a dedicated mounting kit or strap kit may be required to secure it to the bus.
Are accessories like shunt trips or auxiliary switches field-installable on the HFD2020?
Yes, Eaton Series C F-frame breakers support various internal accessories, including shunt trips, auxiliary switches, and bell alarms. These are typically installed in the accessory pockets located under the front cover.
