B-LINE GHC3025 – Frequently Asked Questions
1) Can the Eaton GHC3025 breaker be used on a 480Y/277V three-phase panel?
Yes. The GHC3025 is rated 480Y/277 Vac, and it is a three-pole breaker, so it lands on all three phases of a 480Y/277 system. Its interrupting rating drops at that voltage though: 14 kAIC at 480Y/277 Vac versus 65 kAIC at 240 Vac. Check the available fault current at your panel against the 14 kAIC figure before you install it on the 480V system. It is also rated 125/250 Vdc for DC applications.
2) Is the GHC3025 a complete breaker or just a trip unit I add to a frame?
It ships as a complete molded case breaker, not an interchangeable trip unit or a bare frame. Nothing separate has to be ordered to make it functional. It is a G-frame device in Eaton's Series C line, GHC type, rated 25A.
3) Is the trip setting on the Eaton GHC3025 adjustable?
No. The GHC3025 uses a fixed thermal, fixed magnetic trip unit, so both the overload and the instantaneous settings are factory set at 25A and cannot be dialed in. If your application needs adjustable instantaneous or an electronic trip for coordination, this is the wrong device and you want an adjustable-trip breaker instead.
4) Is a GHC3025 high enough interrupting rating for a 240V service with heavy available fault current?
At 240 Vac the GHC3025 is rated 65 kAIC, which covers most commercial 240V services without needing series ratings or current limiting fuses. That high figure applies only at 240 Vac; at 480Y/277 Vac the rating is 14 kAIC. Match the rating to the voltage you are actually applying it at.
5) Will a GHC3025 fit the space I have in an existing panel or enclosure?
The breaker body measures 4.88 in (height), 3 in (width) and 2.63 in (length) and weighs 1.75 lb. Because it is a G-frame Series C device, it mounts in the G-frame space in Eaton Series C panelboards and enclosures; use the dimensions above to confirm gutter and cover clearance in anything custom.
6) What does the GHC3025 part number actually mean?
Read it in pieces: GHC is the breaker type, the 3 is the number of poles (three-pole), and 025 is the continuous current rating, 25 amps. So a GHC3025 is a three-pole, 25A GHC-type G-frame breaker in Eaton's Series C family. Order by MPN GHC3025.
7) Can I use this 25A breaker on 50 Hz power for export or imported equipment?
Yes, the GHC3025 is rated for 50/60 Hz, so it works on either standard. It also carries a 125/250 Vdc rating for DC circuits.
