Product FAQs
6 answersWhat panelboards are compatible with the QOB2110VH?
Because it features a bolt-on mounting design, it must be installed in Square D NQ or NQOD panelboards. It cannot be used in standard QO load centers, which require plug-on breakers.
How many panel spaces does the QOB2110VH require?
Although it is a 2-pole breaker, the QOB2110VH requires four pole spaces when installed in a single-phase NQ panelboard interior due to its 110A rating and physical size.
What does the "VH" suffix indicate on the QOB2110VH?
The "VH" suffix indicates a higher interrupting rating. While standard QOB breakers are rated at 10kAIC, the QOB2110VH is rated for 22kAIC at 120/240V AC.
What is the plug-on equivalent to the QOB2110VH?
The plug-on equivalent for use in standard QO load centers is the QO2110VH.
Does this breaker include Visi-Trip indication?
Yes, the QOB2110VH features a Visi-Trip indicator that provides a clear visual signal when the breaker has tripped, making it easier to identify faults in a crowded panel.
Is the QOB2110VH rated for DC voltage applications?
Yes, Square D QOB circuit breakers can be used in DC power systems with ratings up to 48V DC.
