Product FAQs
6 answersCan I install the QOB315VH in a standard QO load center?
No. The QOB315VH features a bolt-on connection designed specifically for Square D NQ and NQOD panelboards. Standard QO load centers require plug-on QO breakers.
What does the "VH" suffix indicate on the QOB315VH?
The "VH" designates a very high interrupting rating. While standard QOB breakers provide a 10 kAIC rating, this VH version delivers a 22 kAIC rating at 120/240VAC.
How many panel spaces does the QOB315VH require?
This 3-pole breaker requires three standard 3/4-inch pole spaces in a compatible NQ or NQOD panelboard.
Does the QOB315VH provide ground fault or arc fault protection?
No. This is a standard thermal-magnetic breaker that provides overload and short-circuit protection. It does not include GFCI or AFCI circuitry.
Can the QOB315VH replace a standard QOB315?
Yes, it can physically replace a standard QOB315. It offers an upgraded 22 kAIC interrupting rating compared to the standard 10 kAIC rating of the QOB315.
Does the QOB315VH include a tripped circuit indicator?
Yes, it features the Square D Visi-Trip indicator. When the breaker trips, a highly visible red indicator appears in a small window on the face of the breaker to help quickly identify the tripped circuit.
