Eaton GHB1050 – Frequently Asked Questions
1) What voltage can an Eaton GHB1050 breaker be used on?
The GHB1050 is rated 277 Vac and 125 Vdc, with an interrupting rating of 14 kAIC at 277 Vac. Note the single-pole application limits: 120 Vac max and 125 Vdc max on this device. So a single-pole GHB in a 277/480Y panel is used on the 277 V leg per its rating, but for DC work treat 125 Vdc as the ceiling. It runs on 50/60 Hz systems, so it works on both domestic and 50 Hz installations.
2) Is the Eaton GHB1050 a single-pole 50 amp breaker?
Yes, 50 A single-pole. It is a G-frame GHB-type molded case breaker supplied as a complete breaker, so it ships as the finished device rather than a frame needing a separate trip unit. For a 50 A two-pole load you need the two-pole GHB equivalent, not this one.
3) Will a GHB breaker fit in a panel that currently has GHB breakers in it?
The GHB1050 is a GHB-type, G-frame Series C breaker, so it mounts in gear built for GHB G-frame devices. Match the type and frame stamped on the breaker you are pulling out, confirm the panel accepts a 1 in wide single-pole, and the 50 A rating must not exceed what the circuit conductors and the panel schedule allow.
4) Is 14 kAIC enough interrupting capacity for my panel?
The GHB1050 is rated 14 kAIC at 277 Vac. That has to equal or exceed the available fault current at the point of installation per the engineer's short circuit study. If the calculated available fault current at that panel is above 14 kA, this breaker is the wrong device and you need a higher AIC rating or a series-rated combination documented for the gear.
5) Can the trip setting on the Eaton GHB1050 be adjusted?
No. The GHB1050 uses a fixed thermal, fixed magnetic trip unit, so both the overload and the instantaneous settings are factory set and non-adjustable. If your drawing calls for an adjustable instantaneous trip, you need a different breaker type; for a straight 50 A branch or feeder protection job the fixed unit is what is normally specified.
6) What is the exact part number to order for the Eaton 50 amp GHB single-pole breaker?
Order Eaton GHB1050. That is the manufacturer part number for the Series C complete molded case breaker, single-pole, 50 A. There are no other option choices to specify on it.
7) Where can I get the spec sheet for the Eaton GHB1050?
Eaton publishes a GHB1050 spec sheet, and the link is provided with the product information for trip curve, terminal and mounting detail. If you are submitting on a job, that sheet is what the engineer will want for the 14 kAIC and fixed thermal-magnetic trip data.
