Product FAQs
8 answersWhich Eaton panelboards accept the GHB2050BP12 circuit breaker?
This G-Frame breaker is designed for bolt-on installation in Eaton Series C panelboards, specifically the Pow-R-Line series including PRL1a, PRL2a, PRL3a, PRL1X, and PRL2X models. It is also compatible with select Eaton switchboards and motor control centers.
What is the difference between the GHB2050 and the GHB2050BP12?
There is no difference in the breaker itself. The BP12 suffix simply designates a bulk packaging code for twelve units. You are receiving the standard GHB2050 50-amp, 2-pole molded case circuit breaker.
What wire sizes are compatible with the lugs on this 50A breaker?
The standard lugs on the GHB2050BP12 accept wire gauges from 10 AWG up to 1/0 AWG. The terminals are dual-rated for use with either copper or aluminum conductors.
Is the trip unit on the GHB2050BP12 adjustable?
No, this breaker features a fixed thermal and fixed magnetic trip unit. Both the long-time overload and instantaneous short-circuit trip points are factory-set and non-interchangeable.
What does the LI trip function code mean on this breaker?
The LI code indicates that the thermal-magnetic trip unit provides Long-Time (L) protection for sustained overloads and Instantaneous (I) protection for immediate short-circuit faults.
Can the GHB2050BP12 be used in direct current (DC) systems?
Yes, in addition to its AC ratings, this breaker is certified for use in DC applications up to 125/250V DC, providing a 14kA interrupting capacity for those systems.
Does this breaker snap into the panelboard?
No, the GHB2050BP12 is a bolt-on circuit breaker. It must be mechanically bolted to the panelboard bus, which provides a secure connection suitable for commercial and industrial environments.
Does the GHB2050BP12 provide GFCI or AFCI protection?
No, this is a standard thermal-magnetic molded case circuit breaker designed for overcurrent and short-circuit protection. It does not feature built-in ground fault (GFCI) or arc fault (AFCI) circuitry.

- 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.
