Product FAQs
7 answersWhat panelboards are compatible with the THHQB2190?
This bolt-on breaker is designed exclusively for use in GE A-Series and ABB ReliaGear RQ commercial panelboards.
Can I install the THHQB2190 in a standard GE residential load center?
No. The THHQB2190 is a bolt-on breaker intended for commercial panelboards. Standard GE residential load centers require plug-on breakers, such as the THQL or THHQL series.
What is the difference between the THQB2190 and the THHQB2190?
The primary difference is the interrupting capacity. The standard THQB2190 is rated for 10kAIC, whereas the THHQB2190 is a high-interrupting version rated for 22kAIC at 120/240VAC. Both are 2-pole, 90-amp bolt-on breakers that fit the same panelboards.
Is the THHQB2190 suitable for HVAC applications?
Yes, this breaker is HACR rated. It is approved for use with heating, air conditioning, and refrigeration equipment that requires a 90-amp, 2-pole overcurrent protection device.
What wire sizes are accepted by the THHQB2190 terminals?
The factory-installed box lugs accept 6 to 1/0 AWG copper conductors or 4 to 1/0 AWG aluminum conductors. Ensure the wire is sized appropriately for the 90-amp rating according to the National Electrical Code.
How much panel space does the THHQB2190 require?
This 2-pole Q-Line breaker requires two 1-inch spaces in the panelboard, taking up a total width of 2 inches.
Does the THHQB2190 include GFCI or AFCI protection?
No, this is a standard thermal-magnetic circuit breaker. It provides standard overload and short-circuit protection but does not feature ground fault or arc fault circuitry.
