Product FAQs
6 answersWhat does the "VH" in the QO380VH catalog number indicate?
The "VH" designates a very high interrupting rating. This breaker provides a 22kAIC rating at 120/240VAC and 240VAC, which is higher than the 10kAIC rating found on standard QO breakers.
Can I install the QO380VH in a Square D Homeline panel?
No. QO and Homeline breakers are not interchangeable. The QO380VH is designed exclusively for Square D QO load centers, NQ panelboards, and Speed-D switchboards.
How many panel spaces does the QO380VH require?
As a 3-pole breaker, it requires three standard 3/4-inch spaces in a compatible QO load center or NQ panelboard.
Is there a bolt-on version of this 80A breaker available for NQOD or NQ panelboards?
Yes. If your panelboard requires a bolt-on connection rather than a plug-on type, the correct catalog number is QOB380VH.
Does the QO380VH feature a tripped circuit indicator?
Yes. This breaker includes the Square D Visi-Trip indicator, which displays a highly visible red flag when the breaker has tripped, making it easy to identify the faulted circuit in a crowded panel.
What wire sizes are accepted by the box lugs on the QO380VH?
The box lugs on this 80A breaker accept 4 AWG to 2/0 AWG aluminum or copper wire. Always ensure the connections are torqued to the manufacturer specifications printed on the breaker label.
