Product FAQs
6 answersWhich panelboards are compatible with the THQB32025?
This breaker mounts directly into GE A-Series panelboards and GE AQ Lighting Panels. Because it utilizes a bolt-on connection, it will not fit in standard plug-on load centers.
What is the difference between GE THQB and THQL circuit breakers?
The primary difference is the mounting style. THQB breakers are bolt-on devices built for commercial A-Series and AQ panels. THQL breakers are plug-on units designed for residential load centers. They are not interchangeable.
Can an ABB THQB32025 replace an older General Electric THQB32025?
Yes. Following ABB's acquisition of GE Industrial Solutions, the breakers are manufactured to the same exact specifications. An ABB-branded breaker is a direct drop-in replacement for a legacy GE breaker with the same catalog number.
Is this circuit breaker approved for HVAC applications?
Yes, the THQB32025 is HACR rated. This means it is certified for safely protecting dedicated heating, air conditioning, and refrigeration equipment circuits.
Do the box lug terminals on this breaker accept aluminum wire?
Yes, the terminals are dual-rated for both copper and aluminum conductors. The accepted wire range is 14 to 8 AWG for copper and 12 to 8 AWG for aluminum.
Can the THQB32025 be back-fed in a panelboard?
Yes, this breaker is suitable for reverse-feed applications. Because it bolts directly to the panel bus, it inherently meets securement requirements for back-feeding without the need for a separate hold-down kit.
