Product FAQs
7 answersWhat does the WL suffix mean in the THQC2140WL catalog number?
The WL suffix indicates that the breaker is supplied with both line and load lugs installed from the factory. These lugs accept 8-3 AWG copper or aluminum wire.
Is the THQC2140WL interchangeable with THQL or THQB breakers?
No. While they are all part of the GE Q-Line family, they have different mounting styles. THQL is a plug-in breaker for load centers, THQB is a bolt-on breaker for panelboards, and the THQC2140WL is a lug-to-lug (cable-in, cable-out) breaker designed for DIN rail or base mounting in enclosures and OEM panels.
Will this breaker arrive with GE or ABB branding?
ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, the THQC2140WL may arrive with GE, ABB, or GE by ABB branding. The form, fit, and function remain identical regardless of the label.
How is the THQC2140WL circuit breaker mounted?
This breaker features a feed-thru design and mounts onto a standard 35mm DIN rail or directly to the backpan of an OEM panel or enclosure. It does not plug into or bolt onto a busbar.
What type of trip unit is installed in the THQC2140WL?
It features a fixed thermal magnetic trip unit with Long-Time and Instantaneous (LI) trip functions. The thermal and magnetic settings are fixed and cannot be adjusted in the field.
Can I use aluminum wire with the THQC2140WL?
Yes, the factory-installed lugs are dual-rated for both copper (Cu) and aluminum (Al) conductors ranging from 8 AWG to 3 AWG.
Is the THQC2140WL suitable for HVAC applications?
Yes, standard GE Q-Line breakers like the THQC2140WL are HACR rated, making them suitable for heating, air conditioning, and refrigeration equipment 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!
