B-LINE GHB1050 – Frequently Asked Questions
1) What voltage and amp rating is the Eaton GHB1050 circuit breaker?
The GHB1050 is a 50A single-pole breaker rated 277 Vac and 125 Vdc, with a 50/60 Hz frequency rating. One caveat on the single-pole application: the notes on this breaker call out 120 Vac max and 125 Vdc max, so for single-pole use treat 120 Vac as the ceiling rather than the 277 Vac frame rating.
2) What is the interrupting rating on the GHB1050, and is it enough for my panel?
14 kAIC at 277 Vac. Compare that against the available fault current at the panel where it lands; if your short circuit study calls for more than 14 kA at that point, this G-frame breaker is not the right choice.
3) Will a GHB1050 drop into a panel that already has GHB breakers in it?
Yes. GHB1050 is an Eaton Series C GHB-type, G-frame breaker, so it matches other GHB breakers in the same panel or enclosure. Confirm the panel is rated for 14 kAIC at the applied voltage and that you have a 1 inch single-pole space available.
4) Is the GHB1050 a complete breaker or just a trip unit I have to build up?
It ships as a complete breaker, not a frame plus separate trip unit. The trip is fixed thermal, fixed magnetic, so there is nothing to adjust or specify after ordering, and no rating plug to add.
5) Can the trip setting on the GHB1050 be adjusted in the field?
No. The GHB1050 uses a fixed thermal, fixed magnetic trip, so both the overload and the instantaneous element are factory set at 50A. If your coordination study needs an adjustable instantaneous, you need an electronic-trip breaker in a larger frame instead.
6) Can I use the GHB1050 on a DC circuit?
Yes, up to 125 Vdc. The GHB1050 carries a 125 Vdc rating alongside its AC rating, and the notes confirm 125 Vdc max, which covers typical 125 V DC control and battery circuits. Anything above that needs a breaker with a higher DC rating.
7) What part number do I order for a 50 amp single-pole Eaton GHB breaker?
Order MPN GHB1050. That single part number covers the complete 50A single-pole Series C GHB breaker; there are no finish or accessory options to specify with it.
