Product FAQs
8 answersWhich panelboards are compatible with the GHB2080BP12 circuit breaker?
This G-Frame breaker is designed to bolt into Eaton Series C panelboards, as well as Pow-R-Line 1, Pow-R-Line 2, and Pow-R-Line 3 (PRL1a, PRL2a, PRL3a) panelboards, switchboards, and motor control centers.
How does the GHB2080BP12 mount into the panelboard?
It features a bolt-on mounting style. You will need to secure the breaker directly to the panelboard busbars using the appropriate mounting hardware, ensuring a tight and reliable connection for commercial or industrial applications.
Can this 80-amp breaker be used in DC voltage applications?
Yes, in addition to its 480Y/277V AC rating, the GHB2080BP12 is rated for 125/250V DC systems, providing a 14kA interrupting capacity for direct current applications.
Is there a difference between the GHB2080 and the GHB2080BP12?
The breakers themselves are identical in physical dimensions and electrical specifications. The BP12 suffix simply indicates a bulk packaging format used by the manufacturer for distribution.
What wire sizes and materials are accepted by the lugs on this breaker?
The factory-installed lugs on this 80A breaker accept wire gauges ranging from 10 AWG up to 1/0 AWG. The terminals are rated for use with both copper (Cu) and aluminum (Al) conductors.
Will this breaker work in older Cutler-Hammer panels?
Yes, because Eaton acquired Cutler-Hammer, this breaker is fully backward compatible with legacy Cutler-Hammer Series C and Pow-R-Line panelboards that accept G-Frame GHB breakers.
What type of trip unit does the GHB2080BP12 utilize?
It uses a non-interchangeable thermal-magnetic trip unit. This provides fixed long-time response for standard overload protection and fixed instantaneous response to quickly clear short circuits.
What is the interrupting capacity (AIC) for this breaker on a 240V AC system?
While it is rated for 14kA at 480Y/277V AC, the interrupting capacity increases to 65kA when installed on a 240V AC system.

- MWMARK W.Verified BuyerReviewingEaton / Cutler-Hammer GHB1020 - 20A 1 Pole Molded Case Circuit BreakerRated 3 out of 5 stars7/21/26Good Product, but Disappointed With the Service
Good product, but I was disappointed with the service. I accidentally placed two separate orders and ended up paying freight on both. I had requested that they combine the orders, and had that been done with the freight waived, it would have saved me money.
Other than that, everything was good. I’m just disappointed that no one communicated this to me.
