Product FAQs
6 answersWhat does the L suffix in the FD3020L catalog number indicate?
The L indicates that the breaker comes factory-equipped with both line and load terminals. These standard lugs accept 14 to 1/0 AWG copper or aluminum wire.
Which panelboards and equipment are compatible with the FD3020L?
This Series C F-frame breaker is designed for use in Eaton and Cutler-Hammer FDPW panelboards, switchboards, and motor control centers. It mounts directly to the chassis as a unit-mount device.
Can the FD3020L be used in direct current (DC) applications?
Yes, this thermal-magnetic breaker is rated for up to 250VDC with a 10kA interrupting capacity. When applying it in DC circuits, ensure proper wiring configurations as specified by Eaton guidelines for multi-pole DC switching.
What is the difference between the FD3020L and the FDC3020?
The primary difference is the interrupting capacity. The FD3020L has a standard interrupting rating of 35kA at 480VAC, while the FDC3020 is an ultra-high interrupting version rated at 100kA at 480VAC. Both share the same physical F-frame dimensions.
Are the thermal and magnetic trip settings adjustable on this breaker?
No, the FD3020L features a fixed thermal and fixed magnetic trip unit. If you require adjustable trip settings in a 20A F-frame, you will need an electronic trip unit breaker such as the FDE or HFDE series.
Does this breaker provide ground fault or equipment protection?
No, the FD3020L provides standard long-time and instantaneous (LI) overcurrent and short-circuit protection. It does not include integral ground fault (LSIG) or earth leakage protection.

The breaker we purchased was as advertised. The breaker fit perfectly. We purchased reconditioned breaker and it seems to be working properly, accordingly to the golf course maintenance team that supervises the irrigation system.
Next day shipping came quickly even though the 4th of July was coming.
I wish it came with new installations hardware but that isn’t a deal breaker.
