Product FAQs
6 answersHow many panel spaces does the QO2175VH require?
The QO2175VH requires four standard 3/4-inch panel spaces. Because of its large 175A capacity and wire lug requirements, it takes up more room than standard 2-pole QO breakers.
Can the QO2175VH be used as a main breaker?
Yes, this 175A breaker is frequently used as a main breaker in compatible Square D QO load centers, provided the panel bus is rated for 175A or higher.
What does the VH suffix mean in the QO2175VH part number?
The VH suffix indicates a high interrupting capacity. It signifies that the breaker is rated for 22kAIC at 120/240VAC, whereas standard QO breakers are typically rated at 10kAIC.
Is there a bolt-on version of the QO2175VH available?
Yes. If your NQ or NQOD panelboard requires bolt-on connections, you will need the QOB2175VH instead of this plug-on model.
Will the QO2175VH fit in a Square D Homeline load center?
No. QO series breakers are not interchangeable with Homeline series breakers. The QO2175VH is designed specifically for QO load centers, NQ panelboards, and NQOD panelboards.
Does the QO2175VH include a Visi-Trip indicator?
Yes, this breaker features the Square D Visi-Trip indicator. When the breaker trips due to an overcurrent or short circuit, a highly visible red flag appears to help you quickly identify the faulted circuit.
