Eaton GHC3025 – Frequently Asked Questions
1) Will the Eaton GHC3025 work on a 480Y/277V three-phase panel?
Yes, the GHC3025 is rated 480Y/277 Vac and also 125/250 Vdc. It's a three-pole breaker, so it covers all three phases of a 480Y/277 system. One thing to watch: the interrupting rating drops to 14 kAIC at 480Y/277 Vac, versus 65 kAIC at 240 Vac. If your available fault current at that panel exceeds 14 kA, this breaker is not the right choice.
2) Is the GHC3025 a complete breaker or just a trip unit?
It ships as a complete molded case circuit breaker, not an interchangeable trip unit that needs a separate frame. The GHC3025 is a G-frame, Series C device at 25A, three-pole, so you're installing one assembled unit.
3) Can the trip setting on the Eaton GHC3025 be adjusted in the field?
No. The GHC3025 uses fixed thermal, fixed magnetic trip, so neither the long-time nor the instantaneous setting is adjustable. If your coordination study calls for an adjustable magnetic setting, you need a different breaker type, not this one.
4) Is the GHC3025 suitable for a 240V service with high available fault current?
At 240 Vac the GHC3025 is rated 65 kAIC, which covers most commercial 240V services where fault current is high. That high rating is the main reason to pick a GHC-type G-frame over a lower-interrupting alternative on the same 25A three-pole branch.
5) I need to replace a failed 25 amp three-pole Eaton breaker in a Series C panelboard. Is this the same part?
If the breaker coming out is a GHC-type G-frame, three-pole, 25A Series C unit, the GHC3025 is the direct match by catalog number. Pull the existing breaker and read the number off the face. Eaton frame families are not cross-interchangeable, so a 25A breaker from a different frame letter will not seat in the same mounting.
6) What physical space do I need in the panel for an Eaton G-frame GHC3025?
The breaker measures 4.88 in height, 3 in width, and 2.63 in length, and weighs 1.75 lb. Those are the numbers to check against the available gutter depth and bus spacing in your enclosure before you commit.
7) Can I use the GHC3025 on a DC circuit, like a battery or solar string?
The GHC3025 carries a 125/250 Vdc rating alongside its AC rating, so it can be applied on DC up to those levels. For AC work it is rated 50/60 Hz, which covers both North American 60 Hz and 50 Hz export equipment.
