B-LINE GHC3030 – Frequently Asked Questions
1) What is the interrupting rating of the Eaton GHC3030 breaker at 240V and at 480Y/277V?
The GHC3030 is rated 65 kAIC at 240 Vac and 14 kAIC at 480Y/277 Vac. If your panel's available fault current at the breaker location exceeds 14 kA on a 480Y/277 system, this G-frame GHC will not satisfy the interrupting duty and you need a higher AIC frame.
2) Can I use the GHC3030 on a 480Y/277 volt three-phase panel?
Yes. The GHC3030 carries a 480Y/277 Vac rating and is a three-pole device, so it lands on a three-phase wye system. It is also rated 125/250 Vdc for DC applications. Note the AC rating is the wye value, not 480V delta.
3) Is the trip unit on the Eaton GHC3030 adjustable?
No. The GHC3030 uses a fixed thermal, fixed magnetic trip at 30A, so there are no dials to set. If the job spec calls for an adjustable magnetic trip to ride through motor inrush, this is the wrong device for it.
4) I need to match an existing Eaton breaker in my panel. What part number should I confirm?
Match on the full catalog number GHC3030. Same-frame Eaton breakers can look identical on the panel front while carrying different interrupting ratings, so read the label on the unit you are replacing and confirm it reads GHC3030 before swapping in a 30A three-pole Series C G-frame.
5) Am I ordering a complete breaker or just a trip unit with the GHC3030?
Complete breaker. The GHC3030 ships as a full molded case unit with the trip installed, not as a separate frame plus interchangeable trip. Nothing else has to be ordered to make it a working 30A three-pole breaker.
6) What are the dimensions and weight of the GHC3030 for panel layout?
The GHC3030 measures 4.88 x 3 x 2.63 inches (height, width, length as published) and weighs 1.7 lb. Use those figures when checking gutter space and mounting pan clearance in an existing enclosure.
7) What does the GHC designation mean on an Eaton Series C breaker?
GHC identifies the breaker type within Eaton's Series C molded case line, built on the G-frame. The letters after it in the catalog number give poles and amperage, so GHC3030 is the three-pole, 30 amp version of that type.
8) Will the Eaton GHC3030 work on 50 Hz power for export equipment?
Yes, it is rated 50/60 Hz, so it works on both North American 60 Hz systems and 50 Hz systems found on imported or export-bound machinery.
