Product FAQs
6 answersWhat does the WL suffix mean in the THQC1140WL catalog number?
The WL suffix indicates that the circuit breaker is supplied with both line and load lugs factory-installed.
Are ABB THQC1140WL and GE THQC1140WL the exact same circuit breaker?
Yes. Following ABB's acquisition of GE Industrial Solutions, breakers branded as either ABB or General Electric with this catalog number are identical in form, fit, and function.
How is the THQC1140WL secured inside a control panel?
This feed-thru breaker is designed to snap directly onto a standard 35mm DIN rail. It can also be base-mounted within compatible OEM panels and industrial enclosures.
Can I install the THQC1140WL in a standard GE PowerMark Gold load center?
No. THQC breakers are lug-to-lug devices designed for DIN rail or base mounting in control panels. Standard GE load centers require plug-in THQL or THQP breakers, while commercial panelboards typically use bolt-on THQB breakers.
Is the THQC1140WL suitable for protecting HVAC equipment?
Yes, this breaker is HACR rated, meaning it is tested and approved for use with heating, air conditioning, and refrigeration equipment.
Can the THQC1140WL circuit breaker be reverse fed?
Yes. Standard GE Q-Line thermal magnetic breakers like the THQC1140WL do not have line and load restrictions and can be safely reverse fed in control panel applications.

- 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!
