Product FAQs
5 answersWhat equipment is the FDE322533L circuit breaker designed to fit?
This Series C F-Frame breaker is engineered for installation in Eaton and Cutler-Hammer panelboards, switchboards, and motor control centers (MCCs).
What wire sizes and materials are supported by the standard lugs on the FDE322533L?
The factory-installed line and load terminals accept 4 AWG through 4/0 AWG wire and are rated for both copper (Cu) and aluminum (Al) conductors.
How does the electronic LS trip unit on the FDE322533L differ from standard thermal-magnetic breakers?
The electronic LS trip unit provides adjustable Long-Time and Short-Time settings. This allows panel builders to fine-tune the protection curve for tighter system coordination than a fixed thermal-magnetic breaker can offer.
Are Eaton and Cutler-Hammer FDE322533L breakers the exact same unit?
Yes. Eaton acquired Cutler-Hammer, and the Series C F-Frame breakers are manufactured to the exact same specifications. They are fully interchangeable regardless of which brand name is printed on the label.
Does the FDE322533L mount directly to a busbar?
No, this is a unit-mount, feed-thru circuit breaker. It bolts directly to the panel or enclosure backpan rather than plugging into or bolting onto a distribution busbar.
