Product FAQs
6 answersHow is the THQC2150 circuit breaker mounted inside an electrical enclosure?
The THQC2150 is a lug-to-lug (cable-in, cable-out) miniature breaker that typically mounts onto a standard 35mm DIN rail. It can also be secured directly to a backpan using compatible GE Q-Line screw-type mounting plates or slide-on metal mounting feet.
What wire sizes and materials are compatible with the THQC2150 terminals?
The built-in line and load lugs accept 8 to 3 AWG copper (Cu) wire, or 8 to 2 AWG aluminum (Al) wire.
Why might the THQC2150 arrive with ABB branding instead of General Electric?
ABB acquired GE Industrial Solutions in 2018. Because of this transition, Q-Line breakers like the THQC2150 may be labeled with either the ABB or General Electric logo depending on the manufacturing date. Both versions are mechanically and electrically identical.
Can auxiliary contacts or shunt trips be utilized with the THQC2150?
Yes, Q-Line miniature circuit breakers can be ordered or fitted with auxiliary contact switches and shunt trip accessories to support remote status signaling and automated tripping in control panels.
Can the THQC2150 be applied in 277V or 480V commercial systems?
No, the THQC2150 is strictly rated for a maximum of 120/240V AC. Applying this breaker to a 277V or 480V distribution system exceeds its design ratings and creates a severe safety hazard.
Are the thermal and magnetic trip elements adjustable on the THQC2150?
No. The breaker features a completely fixed thermal-magnetic trip unit with non-interchangeable long-time and instantaneous (LI) trip functions. The 50-amp overcurrent threshold cannot be altered 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!
