Product FAQs
6 answersWhat enclosures or panelboards accept the HFD2040L?
The HFD2040L is designed for use in Eaton Series C panelboards and compatible standalone enclosures. It utilizes a unit mount, feed-thru connection.
Are lugs included with the HFD2040L?

What is the difference between an FD2040 and an HFD2040L?
The HFD prefix indicates a high-interrupting capacity version of the Series C F-Frame breaker. While a standard FD breaker is rated for 35kAIC at 480VAC, the HFD2040L provides a 65kAIC rating at 480VAC. The L suffix means it includes line and load lugs.

No, this breaker features fixed thermal and fixed magnetic trip elements. Neither the long-time nor the instantaneous trip functions are field-adjustable.
What frame size is the HFD2040L?
It belongs to the Eaton Series C F-Frame family. All F-Frame breakers share identical physical dimensions, allowing them to fit the same panelboard spaces regardless of their specific amperage or interrupting rating.
