Product FAQs
6 answersWhat types of systems is the THQC1140 breaker designed for?
This Q-Line breaker is built for OEM panels, custom enclosures, and DIN rail systems. It is a lug-to-lug device, meaning it does not plug into or bolt onto standard residential load center bus bars like THQL or THQB breakers.
Why might this breaker be labeled as ABB instead of General Electric?
Following the ABB acquisition of GE Industrial Solutions, Q-Line breakers are transitioning to ABB branding. A THQC1140 labeled as ABB is identical in form, fit, and function to a GE-branded unit and is fully interchangeable.
What wire gauges are supported by the terminals on the THQC1140?
The line and load lugs accept wire sizes ranging from 8 AWG to 3 AWG. The terminals are compatible with both copper and aluminum conductors.
How is the THQC1140 mounted inside an enclosure?
The breaker is designed to mount directly onto standard 35mm DIN rails within industrial control panels and custom enclosures.
What type of trip protection does the THQC1140 provide?
It utilizes a fixed thermal-magnetic trip unit with long-time and instantaneous (LI) functions. The breaker also features a quick-make, quick-break internal mechanism to minimize arcing during operation.
Is the THQC1140 rated for HVAC equipment?
Yes, GE Q-Line breakers in this 40A class are HACR rated, meaning they are approved for use with heating, air conditioning, and refrigeration equipment.

- 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!
