Product FAQs
6 answersWhat panels and enclosures are compatible with the THQC2120 breaker?
This breaker is designed for use in GE Q-Line enclosures and OEM control panels. It features a bolt-on connection for secure installation and can also be mounted directly to a standard 35mm DIN rail for custom control applications.
What is the difference between GE THQC, THQB, and THQL breakers?
While all are part of the GE Q-Line family, they have different mounting styles. THQL is a plug-on breaker for residential load centers, THQB is a bolt-on breaker for commercial lighting panels, and THQC is a lug-to-lug breaker often used with DIN rail mounting in OEM equipment or specific enclosures.
Is there a difference between ABB and GE THQC2120 breakers?
No. ABB acquired GE Industrial Solutions, so this breaker may arrive with either ABB or GE branding. The form, fit, and function are identical and fully interchangeable.
Is the THQC2120 rated for use with both copper and aluminum wiring?
Yes, the lug terminals are rated for both copper and aluminum conductors, accepting 14-8 AWG copper or 12-8 AWG aluminum wire.
Can this breaker be used in HVAC equipment?
Yes, GE Q-Line breakers like the THQC2120 are HACR rated, making them suitable for heating, air conditioning, and refrigeration motor loads.
Does the THQC2120 include ground fault (GFCI) or arc fault (AFCI) protection?
No, this is a standard thermal-magnetic breaker providing only long-time and instantaneous (LI) overload and short-circuit protection. It does not provide GFCI or AFCI protection.

- 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!
