Built for commercial and industrial applications, the Eaton FD3035 is a 3-pole, 35A molded case circuit breaker from the Series C F-Frame family. It installs into Eaton panelboards, switchboards, and motor control centers, providing reliable thermal-magnetic protection for branch circuits. Rated for 35kAIC at 480VAC and 65kAIC at 240VAC, this bolt-on MCCB features fixed thermal and magnetic trip settings. It includes load-side lugs and is HACR rated for HVAC equipment.
Can the Eaton FD3035 replace an older Westinghouse FD3035 breaker?
Yes. Eaton acquired the Westinghouse distribution equipment line and continues to manufacture the Series C F-frame breakers under the Eaton and Cutler-Hammer brands. The FD3035 is a direct, drop-in replacement for legacy Westinghouse breakers with the exact same catalog number.
What is the difference between the FD3035 and FDB3035 or HFD3035?
The prefix indicates the interrupting capacity of the Series C F-frame breaker. The FD3035 has a standard interrupting rating of 35kAIC at 480VAC. The FDB is rated lower at 14kAIC at 480VAC, while the HFD is a high-interrupting breaker rated at 65kAIC at 480VAC. All three share the same physical footprint.
What type of wire can be used with the FD3035 terminals?
The standard line and load lugs accept 14 AWG to 1/0 AWG wire. The terminals are dual-rated for use with either copper or aluminum conductors.
Is the FD3035 suitable for direct current applications?
Yes. This thermal-magnetic F-frame breaker carries a DC rating of 10kAIC at 250VDC, making it suitable for substantially non-inductive DC circuits.
What enclosures are compatible with the FD3035 circuit breaker?
The FD3035 is designed for bolt-on installation in Eaton Series C panelboards, switchboards, and motor control centers.
Is the Eaton FD3035 HACR rated?
Yes. This breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific protection standard.
Can the trip settings on the FD3035 be adjusted in the field?
No. The FD3035 features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous trip functions are factory-set and cannot be modified.
Does the FD3035 support reverse feed configurations?
Yes. The standard thermal-magnetic Series C F-frame breakers, including the FD3035, are suitable for reverse feed applications.

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.
