Description

Operating at 80 amps, this three-phase molded case breaker provides dependable long-time and instantaneous trip functions for commercial systems. The panel-mount design integrates into Eaton Series C panelboards and motor control centers. Facilities upgrading older infrastructure can replace this exact model with the newer Power Defense PDG23F0080TFFJ. Equipped with load-side lugs, the HACR-rated unit handles 14kA fault currents at 480VAC and allows for reverse feed installations.

Product FAQs

8 answers
Can the FDB3080 be used in reverse feed applications?

Yes, Eaton Series C F-frame circuit breakers, including the FDB3080, are suitable for reverse feed installations.

What is the difference between the FDB3080, FD3080, and HFD3080?

These breakers share the exact same physical dimensions and Series C F-frame footprint. The difference is their interrupting capacity. The FDB3080 is the standard tier, while the FD and HFD models offer higher fault current ratings.

Will this replace a legacy Westinghouse FDB3080?

Yes. Eaton acquired the Westinghouse distribution equipment line. The modern Eaton or Cutler-Hammer FDB3080 is a direct, drop-in replacement for the older Westinghouse branded versions.

Are the trip settings on the FDB3080 adjustable?

No. This breaker features a fixed thermal and fixed magnetic trip unit, meaning the overload and short circuit trip points cannot be adjusted in the field.

What internal accessories can be installed in the FDB3080?

This breaker accepts standard Eaton Series C F-frame internal accessories. You can field-install shunt trips, undervoltage releases, auxiliary contacts, and alarm switches into the accessory cavities under the front cover.

Is the FDB3080 HACR rated?

Yes, all Eaton Series C F-frame molded case circuit breakers carry an HACR rating, making them suitable for heating, air conditioning, and refrigeration equipment branch circuit protection.

Can the FDB3080 be used in DC circuits?

Yes, the thermal-magnetic trip unit allows this breaker to be used in direct current applications. It is rated for up to 250VDC with a 10kA interrupting capacity.

What wire sizes are compatible with the standard lugs?

The factory-installed pressure load terminals accept copper or aluminum conductors ranging from 14 AWG up to 1/0 AWG.
