Product FAQs
6 answersWhat panelboards and load centers are compatible with the QO290VH?
This plug-on breaker is designed exclusively for Square D QO load centers and NQ panelboards. It cannot be installed in Square D Homeline panels or load centers from other manufacturers.
How many panel spaces does the QO290VH require for installation?
As a 2-pole QO series breaker, it requires two standard 3/4-inch spaces in a compatible panel.
What does the VH suffix indicate in the QO290VH catalog number?
The VH suffix indicates a high interrupting rating of 22kAIC at 120/240VAC. This is higher than the 10kAIC rating found on standard QO breakers, making it suitable for applications with higher available fault currents.
Is there a bolt-on equivalent available for the QO290VH?
Yes. If your application requires a bolt-on connection, such as in certain NQ or legacy NQOD panelboards, the equivalent catalog number is QOB290VH.
What wire sizes are accepted by the terminals on the QO290VH?
The box lugs accept 4 AWG to 2/0 AWG aluminum or copper conductors. Always verify that your selected wire gauge meets the 90-amp circuit requirements according to the National Electrical Code (NEC).
Does the QO290VH feature a tripped circuit indicator?
Yes, this breaker includes the Square D Visi-Trip indicator. When the breaker trips due to an overload or short circuit, a red indicator flag appears in the window to help quickly identify the faulted circuit.
