Built for robust industrial applications, the GD3080 is an 80A, 3-pole molded case circuit breaker from Eaton's Series C catalog. Configured for unit mounting, it is compatible with Eaton panelboards, switchboards, and motor control centers. It includes standard lugs for 10-1/0 AWG wire. Providing 22 kAIC at 480VAC, it relies on a fixed thermal-magnetic trip (LI). The device is current limiting, HACR rated, and reverse feed capable.
Yes. This Series C G-frame breaker is fully suitable for reverse feed use. The thermal-magnetic protection functions correctly regardless of which end is wired as the line or load.
Are the standard terminals on the GD3080 compatible with aluminum wiring?
Yes. The standard line and load lugs on this breaker are dual-rated (Cu/Al) to accept either copper or aluminum conductors ranging from 10 AWG to 1/0 AWG.
Can I adjust the trip settings on this 80-amp breaker?
No. The GD3080 is built with a non-interchangeable trip unit featuring fixed thermal (long-time) and fixed magnetic (instantaneous) trip characteristics. The settings cannot be adjusted or swapped out.
What does unit mounting mean for this specific Cutler-Hammer breaker?
Unit mounting indicates this is a cable-in, cable-out device. It fastens directly to a backpan or enclosure using mounting screws, rather than plugging onto or bolting directly to a panelboard busbar.
Can a modern Eaton GD3080 replace an older Westinghouse GD3080?
Yes. Because Eaton acquired the Cutler-Hammer and Westinghouse electrical lines, a current Eaton or Cutler-Hammer GD3080 is structurally identical and serves as a direct drop-in replacement for legacy Westinghouse breakers with the same catalog number.
Is the GD3080 HACR rated?
Yes. This breaker carries an HACR rating, meaning it is tested and approved for group motor applications in heating, air conditioning, and refrigeration equipment.
Does the GD3080 provide ground fault protection?
No. This is a standard thermal-magnetic breaker providing overload and short-circuit protection only. It does not include integral ground fault circuit interruption (GFCI) or equipment protection (EPD) functions.
