Product FAQs
6 answersCan I install the QO2110VH in a Square D Homeline panel?
No. Square D QO and Homeline circuit breakers are not interchangeable. The QO2110VH is designed exclusively for QO load centers and NQ panelboards.
What does the VH stand for in the QO2110VH catalog number?
The VH suffix indicates a high interrupting rating of 22kAIC. Standard QO breakers without this suffix are typically rated for 10kAIC.
Can I use the QO2110VH to replace a standard QO2110?
Yes. The QO2110VH has a higher interrupting rating (22kAIC) than the standard QO2110 (10kAIC). It is safe to use a breaker with a higher interrupting rating than required, provided the panel accepts plug-on QO breakers.
How many panel spaces does the QO2110VH require?
This 110-amp, 2-pole breaker requires two standard 3/4-inch spaces in a compatible QO load center or NQ panelboard.
Is this breaker compatible with bolt-on panelboards?
No. The QO2110VH features a plug-on mounting style. If your panel requires bolt-on connections, you must use a QOB series circuit breaker instead.
Does the QO2110VH include ground fault or arc fault protection?
No. This is a standard thermal-magnetic circuit breaker with long-time and instantaneous (LI) trip functions. It does not provide GFCI or AFCI protection.
