Product FAQs
6 answersWhat types of panels or systems is the THQC2170 compatible with?
The THQC2170 is a Q-Line breaker designed for use in DIN rail systems, OEM panels, and standalone enclosures. Unlike standard plug-on residential breakers, it uses a bolt-on connection and lug terminals for feed-through wiring.
Can the THQC2170 be used as a direct replacement for a THQB breaker?
No. While both belong to the GE Q-Line family, THQB breakers are strap-in models that bolt directly to the bus bar in compatible panelboards. The THQC2170 is a wire-in (feed-through) breaker with lugs on both ends, designed for DIN rail systems or OEM enclosures.
What are the acceptable wire gauges for the THQC2170 terminals?
The load and line lugs accept 6 to 1/0 AWG copper (Cu) conductors or 4 to 1/0 AWG aluminum (Al) conductors. Ensure proper torque specifications are followed during installation.
How does the thermal-magnetic LI trip function operate on this breaker?
The LI designation indicates fixed Long-Time and Instantaneous trip functions. The thermal (Long-Time) element provides delayed tripping for sustained overloads, while the magnetic (Instantaneous) element trips immediately in the event of a short circuit.
What is the maximum fault current the THQC2170 can safely interrupt?
This breaker is rated to safely interrupt up to 10,000 amps (10kAIC) at 120/240VAC. It must not be installed in electrical systems where the available short-circuit current exceeds this threshold.
Why is the THQC2170 listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions, meaning Q-Line breakers like the THQC2170 may carry either the ABB or GE brand logo. Both versions share the same form factor, specifications, and UL listings.

- 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!
