ABB / General Electric THQB2135 Miniature Circuit Breaker

No. THQB breakers feature a bolt-on mounting design intended for commercial A-Series panelboards. THQL breakers are plug-on units designed for standard residential load centers. They are not physically interchangeable.

This breaker is specifically designed for GE A-Series commercial panelboards, including AQ and Spectra series load centers, as well as older RQ panels. It cannot be installed in standard residential GE enclosures.

Yes, this breaker is HACR rated. It is tested and approved for use with Heating, Air Conditioning, and Refrigeration equipment, making it suitable for dedicated HVAC circuits requiring a 35-amp 2-pole breaker.

ABB acquired GE Industrial Solutions in 2018. The product you receive may be branded as either ABB or GE depending on the manufacturing date. Both brands represent the exact same product and are fully interchangeable under manufacturer specifications.

As a bolt-on breaker, it secures directly to the busbar of a compatible commercial panelboard using the integrated mounting hardware. Ensure the panelboard is entirely de-energized before bolting the breaker to the bus to prevent electrical hazards.

The fixed thermal magnetic trip unit provides two types of circuit protection. The long-time thermal function responds to sustained overloads by gradually heating up and tripping, while the instantaneous magnetic function triggers immediately in the event of a severe short circuit.

No. GE THQB breakers require one full inch of space per pole. Unlike the residential THQP series which offers half-inch space-saving breakers, there are no tandem or twin bolt-on configurations available for these commercial panelboards.

This breaker utilizes box lug terminals designed to safely accommodate 8-3 AWG copper or aluminum wiring. For a reliable and code-compliant installation, always tighten the terminal lugs to the exact torque value printed on the side label of the breaker.
