Product FAQs
7 answersWhat does the L suffix indicate in the FD2020L catalog number?
The L signifies that the breaker comes with factory-installed line and load lugs. Without this suffix, the breaker is supplied without terminals.
Which enclosures are compatible with the FD2020L breaker?
This F-frame breaker is designed for use in Eaton Series C panelboards, motor control centers, and switchboards.
What wire sizes are accepted by the standard lugs on this breaker?
The factory-installed lugs accept 14 AWG through 1/0 AWG copper or aluminum wire.
Can the FD2020L be used in direct current systems?
Yes, this breaker is rated for DC applications up to 250VDC, providing an interrupting capacity of 10kA.
Are the trip settings adjustable on this breaker?
No, this breaker features a fixed thermal and fixed magnetic trip unit. Neither the long-time nor the instantaneous trip functions can be adjusted.
What is the difference between the FD2020L and the FDB2020L?
The FD2020L has a higher interrupting rating of 35kA at 480VAC, whereas the standard FDB frame is rated for 14kA at 480VAC. The FD2020L can physically replace an FDB2020L, provided the system requires or allows the higher interrupting capacity.
How is the FD2020L mounted in a panel?
This is a unit mount, feed-thru circuit breaker. It is designed to be bolted directly to the chassis or mounting pan rather than plugging onto a busbar.

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.
