Product FAQs
6 answersWhat does the "WL" suffix mean on the THQC1120WL?
The "WL" suffix indicates that the breaker comes with factory-installed lugs on both the line and load sides. This makes it a cable-in/cable-out, or feed-thru, breaker rather than a plug-in or bolt-on type.
What is the difference between GE THQC, THQL, and THQB breakers?
While all are part of the GE Q-Line family and share a 1-inch per pole width, their mounting methods differ. THQC breakers are cable-in/cable-out and often DIN rail mounted. THQL breakers are plug-in for residential load centers, and THQB breakers are bolt-on for commercial panelboards.
Can I use the THQC1120WL in a standard GE residential load center?
No. Standard GE residential load centers require plug-in THQL or THQP breakers. The THQC1120WL is a lug-to-lug breaker designed for DIN rail mounting or OEM control panels, and it will not connect to standard plug-in busbars.
Are ABB and GE THQC1120WL breakers the exact same product?
Yes. Following ABB acquiring GE Industrial Solutions, these breakers may be branded as either ABB or GE. They are identical in form, fit, and function, and they are fully interchangeable.
Is the THQC1120WL HACR rated?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires this specific certification.
Does the THQC1120WL require a separate adapter for DIN rail installation?
No separate adapter is required. The THQC series features a built-in mounting mechanism designed to snap directly onto standard 35mm DIN rails.

- 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!
