Product FAQs
8 answers
What enclosures or panelboards are compatible with the FDC2090L?
This F-frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers.
What is the difference between Eaton FD, HFD, and FDC circuit breakers?
The prefix indicates the interrupting capacity. In the Series C F-frame family, FD is standard interrupting, HFD is high interrupting, and FDC is the highest interrupting capacity, rated at 100kAIC at 480VAC and 200kAIC at 240VAC.
Can the Eaton FDC2090L be reverse fed?
Yes. Eaton Series C F-frame thermal-magnetic circuit breakers are suitable for reverse feed applications.
Will this breaker replace an older Westinghouse FDC2090L?
Yes. Eaton acquired the Westinghouse distribution equipment division, so the Eaton or Cutler-Hammer FDC2090L is the direct replacement for the legacy Westinghouse FDC2090L.
What wire sizes do the standard lugs on the FDC2090L accept?
The standard lugs accept 14 AWG to 1/0 AWG copper or aluminum wire.
What do the L and I stand for in the trip function code?
The LI trip function indicates the breaker provides Long-Time (thermal) and Instantaneous (magnetic) protection. Both the thermal and magnetic trip settings are fixed on this model.
How does a feed-thru breaker like the FDC2090L mount?
It is a unit-mount breaker, meaning it bolts directly to the mounting surface or panel rather than plugging into or bolting onto a busbar.
Does the L at the end of the FDC2090L catalog number mean anything?
Yes, the L suffix indicates that the breaker is supplied with both line and load side lugs installed from the factory.
