Product FAQs
7 answersWhat panelboards and equipment are compatible with the FD3110 circuit breaker?
The FD3110 is designed for bolt-on installation in Eaton Series C panelboards, switchboards, and motor control centers that accept F-frame breakers.
Can the Eaton FD3110 be used in direct current applications?
Yes, this breaker is rated for 250VDC with a 10kA interrupting capacity, making it suitable for standard DC control and distribution systems.
What wire sizes and materials are supported by the terminals on the FD3110?
The standard factory lugs accept conductor sizes from 4 AWG up to 4/0 AWG and are rated for terminating both copper and aluminum wire.
How does the interrupting capacity of the FD3110 change between 480V and 600V systems?
The breaker provides an interrupting rating of 35kA at 480VAC, but this capacity drops to 18kA when applied in a 600VAC system. Your fault current study must account for this difference at higher voltages.
Does the FD3110 feature adjustable trip settings for coordination studies?
No, the thermal magnetic trip unit features fixed long-time and fixed instantaneous settings that cannot be adjusted in the field.
Is the FD3110 a direct replacement for older Cutler-Hammer or Westinghouse FD breakers?
Yes, Eaton acquired the Westinghouse molded case breaker line. The modern Eaton Series C FD3110 serves as a direct drop-in replacement for legacy Cutler-Hammer and Westinghouse FD3110 breakers.
What specific overcurrent protection profiles does the FD3110 provide?
It is a thermal magnetic breaker with an LI trip function code. This provides fixed long-time thermal protection for standard overloads and instantaneous magnetic protection for short circuits.

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.
