Product FAQs
7 answersWhat does the "WL" suffix indicate on the THQC1170WL catalog number?
The "WL" suffix signifies that the circuit breaker is supplied with factory-installed line and load lugs. If lugs are not required for the application, the base THQC1170 part number is used.
How does the THQC mounting style differ from GE THQL and THQB breakers?
THQC breakers are designed for 35mm DIN rail or base mounting in OEM panels and enclosures. In contrast, THQL models are plug-in breakers for standard load centers, and THQB models are bolt-on breakers for commercial panelboards.
Can the THQC1170WL be reverse fed?
Yes, this thermal-magnetic breaker features reverse feed capability, allowing it to be back-fed in control panels and enclosures where line and load orientations need to be swapped.
How does the breaker indicate a tripped condition?
The operating handle trips to a center position between the ON and OFF markings, providing a clear visual indicator that the breaker has tripped due to an overload or short circuit.
Is this ABB breaker a direct replacement for older General Electric THQC1170WL models?
Yes. Following ABB's acquisition of GE Industrial Solutions, ABB continues to manufacture the Q-Line series. This unit is the exact replacement for legacy GE-branded THQC1170WL breakers, maintaining identical form, fit, and function.
What do the Long-Time and Instantaneous (LI) trip functions indicate on this breaker?
The LI designation refers to the dual-protection thermal-magnetic mechanism. The Long-Time thermal function protects against sustained overloads by tripping on a delay, while the Instantaneous magnetic function clears severe short circuits immediately.
Is the THQC1170WL suitable for HVAC equipment?
Yes, this breaker is HACR rated, making it approved for use with heating, air conditioning, and refrigeration motor loads that require specialized overcurrent protection.

- 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!
