Product FAQs
5 answersWhat panelboards are compatible with the THHQB32090?
This bolt-on Q-Line breaker is designed for use in GE A-Series, GE AQ, and ABB ReliaGear lighting panelboards. It is not compatible with residential PowerMark Gold load centers, which require plug-on breakers.
What is the difference between the THQB32090 and THHQB32090?
Both are 90-amp, 3-pole, bolt-on Q-Line breakers, but they have different interrupting ratings. The standard THQB32090 is rated at 10kAIC, while the THHQB32090 has a higher interrupting capacity of 22kAIC at 240VAC.
Why is this breaker listed as both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. As a result, GE Q-Line breakers like the THHQB32090 are now manufactured and branded under ABB, though they remain exact replacements for legacy GE installations.
What are the wire size and torque specifications for the box lugs?
The terminals accept 6 to 1/0 AWG copper or 4 to 1/0 AWG aluminum wire. The recommended tightening torque is 45 in-lb for #6 to #4 AWG wire, and 50 in-lb for #3 to 1/0 AWG wire.
Does this breaker include ground fault or arc fault protection?
No. The THHQB32090 is a standard thermal-magnetic breaker with long-time and instantaneous (LI) trip functions. It does not provide GFCI or AFCI protection.
