Product FAQs
7 answersWhat panels are compatible with the THQB1130 breaker?
This bolt-on breaker fits GE A-Series panelboards, AQ lighting panels, and ABB ReliaGear RQ commercial panels. It is not compatible with standard PowerMark residential load centers, which require plug-in THQL breakers.
Will this replace legacy GE TQB1130 circuit breakers?
Yes. The THQB series directly replaces older TQB models. Since ABB acquired GE Industrial Solutions, these breakers are manufactured under the ABB and General Electric brands, maintaining full backward compatibility with existing Q-Line hardware.
What are the lug tightening torque specifications for this breaker?
The recommended torque for the box lugs depends on the wire size. Tighten 14 AWG to 10 AWG conductors to 35 inch-pounds. Tighten 8 AWG conductors to 40 inch-pounds.
Is the THQB1130 rated for HVAC equipment?
Yes, this miniature circuit breaker is HACR rated, making it suitable for heating, air conditioning, and refrigeration applications. It features a quick-make, quick-break mechanism for reliable arc isolation.
Does this breaker meet UL 489 standards for commercial applications?
Yes, this device is UL 489 listed for branch circuit protection in commercial and industrial electrical distribution systems. It provides reliable thermal-magnetic overcurrent protection for demanding environments.
Are the trip settings adjustable on this Q-Line breaker?
No, this breaker is equipped with a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous trip functions are pre-calibrated and cannot be adjusted in the field.
Can I use aluminum wire with the THQB1130?
Yes, the standard box lugs are rated for both copper and aluminum conductors. The acceptable wire range is 14 to 8 AWG for copper wire, and 12 to 8 AWG for aluminum wire.
