Product FAQs
6 answersWhat panelboards accept the THQB32050 breaker?
This three-pole unit is designed for General Electric and ABB A-Series panelboards, particularly the AQ lighting and distribution panel lines. It bolts directly to the interior bus.
Can I install the THQB32050 in a standard GE residential load center?
No. This is a bolt-on breaker intended for commercial A-Series panelboards. It cannot be used in load centers that require plug-in THQL or THQP style breakers.
How much physical panel space does this breaker occupy?
The THQB frame is built on a standard one-inch pole width. Because this is a three-pole device, it requires three continuous inches of mounting space on the panelboard bus.
Is this breaker approved for use with HVAC motor loads?
Yes, this breaker is HACR rated. It is evaluated for the specific electrical demands and inrush currents of heating, air conditioning, and refrigeration equipment.
Can the THQB32050 be used to replace older TQB series breakers?
Yes. The current THQB product line is the direct mechanical and electrical equivalent to the legacy TQB series bolt-on breakers.
Can the THQB32050 be used on a 208V three-phase system?
Yes. While the maximum rating is 240VAC, this breaker is fully compatible with 208Y/120VAC three-phase power systems frequently used in commercial applications.
