Product FAQs
8 answersWhat is the difference between THQB and THQL circuit breakers?
THQB breakers like the THQB32070 are bolt-on molded case breakers designed for commercial panelboards, such as GE A-Series and AQ lighting panels. THQL breakers are plug-in units intended for residential load centers. They are not interchangeable.
Can I use the THQB32070 in a standard GE PowerMark load center?
No. Standard GE PowerMark load centers require plug-in THQL or THQP breakers. The THQB32070 is a bolt-on breaker meant strictly for AQ lighting panels and standard A-Series panelboards.
What is the higher interrupting rating alternative to the THQB32070?
The THHQB32070 is the direct physical upgrade, offering a 22kAIC interrupting rating compared to the 10kAIC rating of the standard THQB32070.
Did the catalog number change after ABB acquired GE Industrial Solutions?
No, ABB retained the original GE Q-Line part numbers. The breaker may arrive with ABB or GE branding, but the THQB32070 remains the exact same product.
How does the THQB32070 attach to the panelboard bus?
As a bolt-on breaker, the THQB32070 features screw tabs that fasten directly to the panelboard bus, providing a rigid connection designed to withstand commercial environments and reduce arcing risks.
Do I need to purchase terminal lugs separately for the THQB32070?
No, the THQB32070 comes factory equipped with load side box lugs that are rated for both copper and aluminum conductors.
Can the THQB32070 be used on 480V systems?
No, this breaker has a maximum voltage rating of 240VAC. For 480V applications, a different frame type such as the GE Spectra or TEY series is required.
Does the THQB32070 offer ground fault or arc fault protection?
No, the THQB32070 is a standard thermal magnetic circuit breaker providing overload and short-circuit protection. It does not include GFCI or AFCI capabilities.
