Product FAQs
6 answersWhat type of panels or enclosures can the THQC1120 be installed in?
This breaker features a cable-in, cable-out lug design that mounts onto a standard 35mm DIN rail or bolts directly into custom OEM panels and control enclosures.
Will the THQC1120 fit in a standard GE Powermark residential load center?
No. GE residential load centers typically require plug-on type breakers. The THQC1120 is a bolt-on, lug-to-lug breaker designed for industrial panels, machinery, and DIN rail applications.
Can I use aluminum wire with the lugs on this breaker?
Yes, the lug terminals on the THQC1120 accept both copper and aluminum wiring. Acceptable wire ranges are 14 to 8 AWG for copper and 12 to 8 AWG for aluminum.
Is there a difference between the GE THQC1120 and the ABB THQC1120?
No, they are the exact same component. ABB acquired the GE Industrial Solutions division, so this breaker is fully interchangeable and maintains the same footprint whether it is branded as GE or ABB.
Does the THQC1120 feature ground fault (GFCI) or arc fault (AFCI) protection?
No. The fixed LI (Long-Time and Instantaneous) trip function indicates this is a standard thermal-magnetic breaker providing overload and short-circuit protection only.
Can the THQC1120 be used as a feed-thru breaker?
Yes, the THQC series operates as a feed-thru, cable-in and cable-out breaker, meaning conductors are connected directly to the mechanical lugs on both the line and load sides.

- POPaul O.Verified BuyerReviewingABB / General Electric THQC2150 - 50A 2 Pole Molded Case Circuit BreakerI recommend this productRated 4 out of 5 stars9/3/26Recent Breaker Purchases
These breakers matched perfectly for my main AC supplies for my boat. I had the original 43-year-old Chinese (GenFu) breakers that failed and these GEs were a perfect match. My only reservation for not providing a 5-star review is breakers do not arrive in GE's original packaging which can lead to questions whether they are truly "new" breakers. Otherewise, happy I found some that replaced my originals. Thanks SB!
