B-LINE GHC3100 – Frequently Asked Questions
1) What voltage and interrupting rating does the Eaton GHC3100 breaker carry?
The GHC3100 is rated 480Y/277 Vac and 125/250 Vdc, with an interrupting capacity of 65 kAIC at 240 Vac and 14 kAIC at 480Y/277 Vac. That 14 kAIC figure is the number to check against your available fault current if you are feeding it from a 480Y/277 panel, because the high 65 kAIC value only applies at 240 Vac.
2) Is the GHC3100 a three-phase breaker, and what amperage is it?
Three-pole, 100 amp. That makes it a three-phase device for a 3-phase panel or a 3-pole disconnect on DC. If you need single or two-pole protection at 100A, this is the wrong catalog number.
3) Is the trip unit on the GHC3100 adjustable?
No. The GHC breaker uses a fixed thermal, fixed magnetic trip, so neither the long-time nor the instantaneous setting can be dialed in. If your coordination study calls for an adjustable magnetic or an electronic trip unit, you need a different trip style, not this one.
4) What frame size is the GHC3100 and will it fit my existing G-frame cutout?
This is a G-frame breaker from Eaton's Series C line. Its body measures 4.88 in height, 3 in width, and 2.63 in length, and it weighs 1.75 lb. Compare those against the space in your panel or enclosure before you commit, and confirm your existing unit is also a Series C G-frame.
5) Does the GHC3100 come as a complete breaker or just the frame?
It ships as a complete molded case circuit breaker, frame and trip together, not a bare frame needing a separate trip unit. What it does not include is mounting or connection accessories such as lugs, terminal kits, or a panel mounting kit; order those separately if the application needs them.
6) Can the GHC3100 be used on a DC circuit?
Yes. Along with its 480Y/277 Vac rating it carries a 125/250 Vdc rating, so it can serve DC applications like battery or UPS distribution within that voltage. On AC it is rated for 50/60 Hz, which covers both North American and 50 Hz international systems.
7) What exact part number should I order for this Eaton 100A G-frame breaker?
Order by the Eaton catalog number GHC3100. That single number defines the three-pole, 100 amp, fixed-trip Series C G-frame breaker, so there are no suffixes or option codes to add for the base unit.
