Product FAQs
5 answersWhat panelboards are compatible with the QOB2100VH?
The QOB2100VH is designed for use in Square D NQ and NQOD panelboards. It features a bolt-on connection and is not compatible with standard QO load centers, which require plug-on breakers.
What is the difference between the QO2100VH and the QOB2100VH?

What does the VH suffix in the QOB2100VH catalog number indicate?
