Product FAQs
5 answersCan I install the THQC32045WL in a standard GE load center?
No. Unlike THQL plug-on or THQB bolt-on breakers, the THQC series features a feed-thru design for DIN rail mounting. It is intended for OEM panels, enclosures, and custom DIN rail systems.
What does the WL suffix mean on the THQC32045WL?
The WL suffix indicates the breaker includes factory-installed lugs on both the line and load sides for feed-thru connections. These lugs accept 8 AWG to 3 AWG copper or aluminum conductors.
Will my THQC32045WL breaker be branded as ABB or GE?
It may arrive with either branding. Following ABB's acquisition of GE Industrial Solutions, Q-Line breakers are produced under both names but remain identical in form, fit, and function.
Are the thermal-magnetic trip settings adjustable on this breaker?
No. The THQC32045WL features a fixed trip unit. The long-time (overload) and instantaneous (short-circuit) protection points are factory calibrated and cannot be modified in the field.
Is the THQC32045WL suitable for high fault current applications?
This breaker is limited to a 10kAIC interrupting rating at 240VAC. It must not be installed in systems where the available fault current exceeds 10,000 amps.

- 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!
