Product FAQs
6 answersWhat is the difference between the QOB230 and QOB230VH circuit breakers?
The VH suffix designates a higher interrupting capacity. While the standard QOB230 provides a 10 kAIC rating, the QOB230VH is rated for 22 kAIC at 120/240VAC.
Can I install this bolt-on breaker in a standard QO load center?
No. The QOB230VH features a bolt-on mounting design engineered strictly for Square D NQ and NQOD panelboards. Standard residential QO load centers require plug-on circuit breakers.
What is the recommended terminal tightening torque for this 30A breaker?
For the pressure plate terminals on the QOB230VH, the manufacturer specified tightening torque is 40.7 lb-in (4.6 N.m).
How much space does the QOB230VH require in a panelboard?
As a 2-pole breaker, it requires two standard 3/4-inch spaces on the NQ or NQOD panelboard bus.
Is the QOB230VH suitable for use with HVAC equipment?
Yes. This thermal-magnetic circuit breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment branch circuits.
Does this breaker feature visual trip indication?
Yes. The QOB230VH includes the Square D Visi-Trip indicator. When the breaker trips due to an overcurrent or short circuit, the handle rests in a center position and a highly visible red flag appears to help quickly locate the faulted circuit.
