Eaton GHB2090 – Frequently Asked Questions

1) Will an Eaton GHB2090 breaker work on a 480Y/277V panel?
Yes, the GHB2090 is rated 480Y/277 Vac, and also 125/250 Vdc. One thing to watch: the interrupting rating drops with voltage. It is 65 kAIC at 240 Vac but 14 kAIC at 480Y/277 Vac, so check the available fault current at your 480Y/277 bus against 14 kAIC before you install it.
2) Can I adjust the trip setting on the Eaton GHB2090?
No. The GHB2090 uses fixed thermal and fixed magnetic trip, so both the overload and the instantaneous settings are factory set at 90A and cannot be dialed in. If your application needs field-adjustable instantaneous or an adjustable trip unit, this is the wrong breaker type to specify.
3) Is the GHB2090 the right replacement for an existing GHB two-pole 90 amp breaker?
It is a Series C GHB-type breaker, two-pole, 90A, so it matches on type, pole count and rating for a like-for-like GHB swap. Confirm the breaker you are pulling out is also a GHB G-frame unit rather than a different Eaton frame, and that its interrupting rating is no higher than 65 kAIC at 240 Vac or 14 kAIC at 480Y/277 Vac, since dropping to a lower AIC than the panel requires is not a legal substitution.
4) What space does the GHB2090 take up in a panel or enclosure?
It is a G-frame breaker measuring 4 x 2.63 x 2 inches and weighing 1.15 lb. The 2 inch width is the number that usually decides whether it fits your available pole space; use the 4 inch and 2.63 inch figures for enclosure depth and height clearance.
5) Is the GHB2090 a complete breaker or do I need to order a trip unit separately?
It ships as a complete breaker. The GHB2090 is a molded case breaker with the thermal-magnetic trip built in, so there is no separate trip unit or rating plug to buy to make it functional.
6) What is the exact part number to order for this 90A two-pole Eaton breaker?
The manufacturer part number is GHB2090. In Eaton's naming, GHB is the breaker type, 2 is the pole count and 090 is the 90 amp rating, which is how you cross-check it against a panel schedule.
7) Does this Eaton breaker work on 50 Hz power?
Yes. The GHB2090 is rated 50/60 Hz, so it is usable on 50 Hz systems as well as standard 60 Hz North American power, within its 480Y/277 Vac rating.
