Designed for standalone and feed-thru applications, the Eaton FD3090L is a 3-pole, 90A molded case circuit breaker from the Series C F-Frame line. It provides long-time and instantaneous (LI) thermal-magnetic protection for commercial and industrial systems. Unlike standard bolt-on models, this unit mount breaker includes both line and load side lugs for versatile installation in switchboards and enclosures. It features a 35kAIC rating at 480V, HACR certification, and reverse feed capability.
What does the "L" in the FD3090L catalog number indicate?
The "L" signifies that the circuit breaker includes factory-installed line and load side lugs, which accept 14 AWG to 1/0 AWG copper or aluminum wire.
Can the FD3090L be reverse fed?
Yes, this thermal magnetic Series C F-frame breaker is suitable for reverse feed applications.
Will this breaker fit in older Westinghouse panelboards?
Yes, Eaton Series C breakers are the direct continuation of the Westinghouse line and will fit in enclosures and panelboards designed for Westinghouse F-frame breakers.
Can the FD3090L replace other Series C F-frame breakers like the FDB3090 or FDC3090?
Yes, it shares the same physical dimensions and mounting footprint as other F-frame breakers. You must ensure the FD3090L interrupting ratings meet or exceed your specific system fault current requirements before substituting.

175amp molded case circuit breaker
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.
