B-LINE GHC3050 – Frequently Asked Questions
1) What voltage and amperage is the Eaton GHC3050 circuit breaker rated for?
The GHC3050 is a 50 amp, three-pole molded case breaker rated 480Y/277 Vac and 125/250 Vdc, at 50/60 Hz. The 480Y/277 rating means it is intended for a wye-connected system with a grounded neutral, not for a 480V delta or corner-grounded system.
2) What is the interrupting rating of the GHC3050 breaker?
65 kAIC at 240 Vac and 14 kAIC at 480Y/277 Vac. If your available fault current at the panel exceeds 14 kA on a 480Y/277 system, this G-frame breaker is not the right interrupting class for that location.
3) Is the GHC3050 a complete breaker or just a trip unit?
It ships as a complete breaker, so there is no separate trip unit or frame to order alongside it. The trip is fixed thermal and fixed magnetic, meaning no field adjustment of the trip settings.
4) Can I adjust the trip setting on the Eaton GHC3050?
No. The GHC3050 uses a fixed thermal, fixed magnetic trip, so the 50A rating is what you get. If the job calls for adjustable instantaneous or an electronic trip unit, you need a different frame and trip combination.
5) What are the dimensions and weight of the GHC3050 so I can check it fits my enclosure?
The breaker measures 4.88 in height, 3 in width, 2.63 in length, and weighs 1.7 lb. Those are the G-frame footprint numbers to check against your panel gutter space and cover cutout.
6) Can the GHC3050 be used on a DC circuit?
Yes, it carries a 125/250 Vdc rating alongside the 480Y/277 Vac rating, so it can be applied on DC systems within that voltage. It is also rated for 50/60 Hz AC, which covers both North American and 50 Hz installations.
7) What is the exact Eaton part number to order for this 50 amp three-pole G-frame breaker?
The manufacturer part number is GHC3050. In that designation GHC is the breaker type and 3050 reads as three poles at 50 amps, which is consistent with the three-pole, 50A ratings on the unit.
