Product FAQs
8 answersWhat equipment is the HFD3020 circuit breaker designed to fit?
This F-Frame breaker mounts into Eaton Series C panelboards, motor control centers (MCC), and switchboards that are specifically configured to accept bolt-on branch breakers.
What wire sizes do the factory lugs on the HFD3020 accept?
The factory-installed lugs accept 14 AWG through 1/0 AWG copper or aluminum wire. Installers must ensure conductors are torqued to the specifications printed on the breaker label to maintain a safe, compliant connection.
Can the Eaton HFD3020 replace an older Cutler-Hammer or Westinghouse HFD3020?
Yes. Eaton acquired the Cutler-Hammer and Westinghouse distribution lines. A modern Eaton HFD3020 is a direct, drop-in replacement for legacy Cutler-Hammer and Westinghouse breakers bearing the exact same catalog number.
Can the thermal or magnetic trip settings be adjusted on this breaker?
No. The HFD3020 features a fixed thermal and fixed magnetic trip unit. The trip parameters are set at the factory and cannot be field adjusted.
Is the HFD3020 suitable for direct current (DC) applications?
Yes, this breaker is rated for up to 250VDC with an interrupting capacity of 22kA. When installing in DC circuits, always consult the manufacturer guidelines for the proper wiring configuration, such as wiring multiple poles in series.
What does the H in the HFD3020 part number signify?
The H designates this as the high-interrupting capacity version of the Series C F-Frame breaker. The HFD3020 provides a 65kA rating at 480VAC, which is higher than the standard FD3020 rated at 35kA for the same voltage.
How does the HFD3020 physically mount into a panelboard?
It utilizes a bolt-on mounting style. Instead of clipping onto a rail or plugging into a socket, the breaker terminals are physically bolted directly to the panel busbars for a secure, high-vibration resistant connection.
What specific circuit protection does the LI designation on this breaker provide?
The LI designation indicates Long-Time and Instantaneous trip functions. The long-time thermal function protects the circuit against sustained overloads, while the instantaneous magnetic function provides immediate tripping during severe short circuits.
