Product FAQs
7 answersWhich panelboards accept the FB3080 circuit breaker?
This breaker is specifically designed for bolt-on installation in Westinghouse and Eaton Pow-R-Line panelboards, switchboards, and motor control centers.
Can the Eaton FB3080 be reverse fed?
Yes. Eaton F-Frame molded case circuit breakers do not have line and load restrictions and are suitable for reverse feed applications.
Are lugs included with the FB3080, and what wire material is supported?
Yes, the breaker comes with standard lugs that are dual-rated for both copper and aluminum (Cu/Al) conductors ranging from 14 AWG to 1/0 AWG.
Is this the correct replacement for an older Westinghouse FB3080 breaker?
Yes. Eaton acquired the Westinghouse distribution equipment line, making this Eaton / Cutler-Hammer FB3080 the exact direct replacement for legacy Westinghouse breakers with the same catalog number.
Does the FB3080 provide ground fault or arc fault protection?
No. This is a standard thermal-magnetic breaker with fixed long-time and instantaneous (LI) trip functions. It does not offer GFCI or AFCI protection.
Is the FB3080 suitable for HVAC equipment?
Yes. All Eaton F-Frame circuit breakers are HACR rated, making them suitable for use with heating, air conditioning, and refrigeration equipment.
Can the thermal or magnetic trip settings on the FB3080 be adjusted?
No. This breaker features a fixed thermal and fixed magnetic trip unit, meaning the overcurrent and short-circuit trip thresholds cannot be adjusted in the field.
