Product FAQs
6 answersWhat types of equipment can the FD1045 be installed in?
This Series C F-frame breaker is designed for installation in Eaton panelboards, switchboards, motor control centers, and dedicated F-frame enclosures.
Is the Eaton FD1045 a direct replacement for older Westinghouse breakers?
Yes. Eaton acquired the Westinghouse distribution equipment line, and the Series C FD1045 is the official, manufacturer-supported replacement for legacy Westinghouse and Cutler-Hammer 1-pole FD-frame breakers with matching specifications.
Can the FD1045 be used in direct current (DC) circuits?
Yes, it is rated for use in 125VDC applications, where it provides a 10kA interrupting capacity. This makes it suitable for specific control circuits and DC power distribution.
Is this breaker rated for 347V commercial lighting systems?
Yes, the FD1045 supports 347VAC applications with an 18kA interrupting rating, which is commonly required for industrial and commercial lighting circuits.
What wire sizes and materials do the standard lugs accept?
The standard lugs on the FD1045 accommodate wire gauges from 14 AWG up to 1/0 AWG. They are dual-rated for both copper (Cu) and aluminum (Al) conductors.
Can I adjust the trip curve or instantaneous trip settings on this breaker?
No, the FD1045 features a fixed thermal-magnetic trip unit. Both the long-time (thermal) and instantaneous (magnetic) trip functions are factory-set and cannot be adjusted in the field.

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.
