Built for versatile industrial power distribution, the Eaton FD2035L delivers 35A of continuous current handling. It utilizes a fixed thermal-magnetic trip unit to provide reliable long-time and instantaneous protection. Featuring a unit mount design with factory-installed line and load lugs, it installs into Series C switchboards and control panels. This feed-thru configuration is ideal for standalone enclosures. Rated 65kAIC at 240V, it safely clears faults and is reverse feed capable.
What does the L suffix in the FD2035L catalog number indicate?
The L suffix signifies that the breaker is factory-equipped with standard line and load side lugs. Without this suffix, the breaker frame is typically supplied without terminal connectors.
Is the FD2035L a direct replacement for older Westinghouse or Cutler-Hammer models?
Yes, Eaton acquired Cutler-Hammer and Westinghouse distribution equipment. This Series C breaker is a direct drop-in replacement for legacy Cutler-Hammer and Westinghouse FD2035L breakers, sharing the exact same physical dimensions and mounting footprint.
Can this F-Frame breaker be used in direct current (DC) applications?
Yes, this thermal magnetic breaker is rated for up to 250VDC with a 10kA interrupting capacity, making it suitable for specific DC control circuits and distribution panels.
Are the trip settings adjustable on this specific model?
No, this breaker features fixed thermal and fixed magnetic trip elements. If your application requires field-adjustable trip settings, you will need to look at electronic trip units or different Series C frames.
What type of enclosures or panels accept this breaker?
This is a unit mount, feed-thru breaker designed for hardwired installations in Eaton Series C panelboards, switchboards, and motor control centers. It is not a plug-on style breaker.
What wire sizes are compatible with the included lugs?
The factory-installed lugs accept 14 AWG through 1/0 AWG conductors and are rated for both copper and aluminum wiring.
Can I mount the FD2035L directly to a standard DIN rail?
No, this F-Frame breaker is designed for base mounting or panelboard installation. It cannot be snapped directly onto a standard 35mm DIN rail without a specialized adapter plate.

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.
