Description
Designed for industrial switchgear environments, the FDB2080L provides robust thermal-magnetic overcurrent defense. The "L" suffix designates the inclusion of both line and load terminals for unit-mount flexibility. Installers can integrate this 2-pole device into Eaton Series C motor control centers and standalone enclosures. For facility upgrades, it acts as a functional predecessor to the modern PDG22F0080TFFJ Power Defense frame. The breaker achieves a 14kA interrupting capacity at 480V.Specifications

Product FAQs
6 answersWhat enclosures or panelboards accept the FDB2080L?
This F-frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers. It requires a standard Series C F-frame mounting space.
What does the L suffix in FDB2080L signify for installation?
The L suffix indicates that the breaker comes factory-equipped with line and load lugs. These terminals are rated to accept 14 to 1/0 AWG copper or aluminum conductors.
Can this breaker replace older Westinghouse FDB models?
Yes, Eaton manufactures this breaker as a direct replacement for legacy Cutler-Hammer and Westinghouse FDB2080L breakers. They share the exact same physical dimensions, mounting footprint, and Series C frame design.
Is the trip unit on the FDB2080L adjustable?
No, this breaker features a fixed thermal and fixed magnetic trip unit. Neither the long-time nor the instantaneous trip functions can be adjusted in the field.
How is the FDB2080L mounted inside a panel?
This is a unit mount, feed-thru circuit breaker. It bolts directly to the chassis or mounting pan and uses wire connections on both the line and load sides, rather than plugging onto a busbar.
Can the FDB2080L be used in DC electrical systems?
Yes, it is rated for DC applications up to 250VDC with an interrupting capacity of 10kA. When installing in DC systems, ensure your wiring configuration aligns with Eaton guidelines for 2-pole thermal magnetic breakers.
