Product FAQs
8 answersWhat type of panels or enclosures are compatible with the THQC2150WL?
This miniature molded case breaker mounts directly to a standard 35mm DIN rail. It is a feed-thru (lug-lug) breaker used in OEM equipment, industrial control panels, and standalone enclosures, and is not designed for traditional plug-on residential load centers.
What does the WL suffix indicate on this ABB/GE circuit breaker?
The WL suffix in the Q-Line catalog number signifies that the breaker is a cable-in/cable-out configuration and includes factory-installed mechanical line and load lugs suitable for copper or aluminum conductors.
Is the THQC2150WL approved for HVAC equipment?
Yes, this 50-amp Q-Line breaker carries a HACR rating, certifying it for the demanding inrush currents and continuous load profiles associated with heating, air conditioning, and refrigeration equipment.
Can the THQC2150WL be used in a reverse feed configuration?
Yes. Specifications confirm this breaker is suitable for reverse feeding. Line power can be terminated at either the upper or lower lugs without compromising the internal thermal-magnetic trip functionality.
What conductor sizes are accepted by the lugs on the THQC2150WL?
The factory lugs accommodate wire gauges from 8 AWG to 3 AWG for copper (Cu) conductors, and 8 AWG to 2 AWG for aluminum (Al) conductors.
Will the breaker still trip if the operating handle is physically held in the ON position?
Yes. The internal quick-make/quick-break mechanism is trip-free, ensuring the breaker will safely interrupt an overcurrent or short circuit fault regardless of external physical restriction on the handle.
How does the THQC2150WL visually indicate a tripped condition?
When a fault occurs, the operating handle moves to a central position midway between ON and OFF. To restore power, the handle must be toggled completely to the OFF position to reset the mechanism before switching it back to ON.
Why is this THQC breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions, meaning the legacy GE Q-Line circuit breakers are now manufactured under the ABB brand. The footprint, performance, and THQC catalog numbers remain fully identical and interchangeable.

- 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!
