Yes, GE Q-Line breakers like the THQC1150 are HACR rated, making them suitable for heating, air conditioning, and refrigeration applications.
What does the LI trip function code mean on the THQC1150?
The LI designation indicates that the breaker provides Long-Time (L) and Instantaneous (I) trip functions. The long-time function protects against sustained overloads, while the instantaneous function protects against short circuits.
Is the trip unit on the THQC1150 adjustable?
No, the THQC1150 features fixed thermal and fixed magnetic trip settings. It cannot be adjusted in the field.

- 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!
