Product FAQs
6 answersCan I install the QO315VH in a Square D Homeline load center?
No. QO series breakers are not interchangeable with Homeline panels. The QO315VH is designed exclusively for QO load centers, NQ panelboards, and NQOD panelboards.
What does the VH suffix in the QO315VH catalog number indicate?
The VH suffix designates a higher interrupting rating of 22kA at 120/240VAC. Standard QO breakers without this suffix typically have a 10kA interrupting rating.
How many panel spaces does this 3-pole breaker require?
The QO315VH requires three standard 3/4-inch spaces, taking up a total of 2.25 inches on the bus bar.
Does this breaker feature the Visi-Trip indicator?
Yes, it includes the Square D Visi-Trip red indicator, which provides a clear visual confirmation when the breaker has tripped.
Can I use the QO315VH to replace a standard QO315?
Yes, the QO315VH has the same physical dimensions and mounting style as the standard QO315, but it provides a higher 22kA interrupting rating for applications requiring greater fault current protection.
Is the QO315VH suitable for HVAC equipment?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires motor group combinations.
