Product FAQs
9 answersWhat enclosures and panelboards are compatible with the FDC2020L?
This breaker is designed for use in Eaton and Cutler-Hammer Series C panelboards, switchboards, and motor control centers. It is an F-frame breaker and will not fit in standard residential load centers.
How is the FDC2020L mounted in an enclosure?
It is a unit mount, feed-thru circuit breaker. This means it bolts directly to the backpan or mounting plate of the enclosure rather than plugging into or bolting onto a panelboard bus.
What does the L suffix indicate in the FDC2020L catalog number?
The L suffix indicates that the breaker is supplied from the factory with line and load terminal lugs included.
How does the FDC series differ from standard FD or FDB breakers?
The FDC series offers the highest interrupting capacity within the Eaton Series C F-frame family. It provides up to 100kAIC at 480VAC, whereas standard FD or FDB breakers have significantly lower fault current ratings.
What wire sizes are accepted by the standard lugs on this 20A breaker?
The factory lugs accept wire gauges from 14 AWG up to 1/0 AWG. The terminals are rated for both copper and aluminum conductors.
Can I use this breaker to replace an older Westinghouse FDC2020L?
Yes. Eaton acquired the Westinghouse distribution equipment line. A modern Eaton or Cutler-Hammer FDC2020L is the exact same form, fit, and function as the legacy Westinghouse model.
Is this breaker suitable for direct current applications?
Yes, the FDC2020L is rated for up to 250VDC with a direct current interrupting rating of 22kAIC, making it suitable for specific industrial DC control circuits.
Can the thermal or magnetic trip settings be adjusted on this model?
No. This breaker features a fixed thermal and fixed magnetic trip unit. If your application requires adjustable trip settings, you will need an electronic trip unit or a different frame class.
What safety procedures are required before installing or servicing this breaker?
Always de-energize the switchboard or panelboard before installation. Verify that no voltage is present across the line terminals using a properly rated multimeter, and follow all OSHA lockout and tagout procedures.
