Product FAQs
11 answersCan I install the THQC21100WL in a standard GE plug-in load center?
No. The THQC series is designed for 35mm DIN rail mounting or base mounting in OEM panels and enclosures. For standard GE plug-in residential load centers, a THQL series breaker is required.
Does the THQC21100WL require a specific DIN rail size?
Yes, it is designed to mount directly onto standard 35mm DIN rails, which are commonly used in industrial control panels, automation cabinets, and custom enclosures.
What does the WL suffix indicate on the THQC21100WL catalog number?
The WL suffix designates that the breaker comes with both line and load lugs factory-installed. This lug-to-lug configuration allows for direct feed-thru wiring without requiring a busbar connection.
Does this breaker feature a trip-free mechanism?
Yes, the quick-make, quick-break mechanism is trip-free. This ensures the breaker will trip under overload or short circuit conditions even if the operating handle is physically held or locked in the ON position.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. The THQC product line continues to be manufactured under the same catalog numbers, meaning an ABB-branded THQC21100WL is identical to a GE-branded unit.
What is the difference between the THQC and THQB circuit breakers?
The THQC series is designed for DIN rail or base mounting with lug connections. The THQB series is a bolt-on breaker designed specifically to bolt directly to the bus in GE lighting panels and commercial load centers.
Is the THQC21100WL suitable for HVAC equipment?
Yes, this breaker is HACR rated. It is approved for use with heating, air conditioning, and refrigeration equipment that requires group motor protection.
Can this breaker be used in a 480V or 277/480V system?
No, the THQC21100WL is strictly rated for a maximum of 120/240VAC. Applying it to a 480V system exceeds its maximum voltage rating and violates safety standards. For 480V applications, a different frame type like the TED or TEY series is required.
Can I adjust the trip settings on the THQC21100WL?
No, this breaker features a fixed thermal-magnetic trip unit. The long-time and instantaneous trip functions are factory calibrated and non-interchangeable.
How does the common trip feature work on this 2-pole breaker?
An internal common trip bar ensures that if an overcurrent or short circuit occurs on either pole, both poles will disconnect simultaneously. This completely de-energizes the 240V circuit for safety.
Does the THQC21100WL provide visual trip indication?
Yes. When the breaker trips, the handle moves to a center position midway between ON and OFF. To reset the breaker, the handle must be pushed completely to the OFF position before turning it back ON.

- 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!
