Product FAQs
6 answersCan I install the QOB250VH in a standard QO load center?
No. The QOB250VH features a bolt-on connection designed specifically for Square D NQ and NQOD panelboards. Standard QO load centers require plug-on circuit breakers.
What does the VH stand for in the QOB250VH part number?
The VH designates this as a very high interrupting rating circuit breaker. It provides a 22kAIC fault current rating at 120/240VAC, which is higher than the 10kAIC rating found on standard QOB breakers.
How much panel space does the QOB250VH require?
This two-pole miniature circuit breaker requires two standard 3/4-inch spaces in a compatible NQ or NQOD panelboard.
What is the recommended tightening torque for the box lugs on this breaker?
The recommended tightening torque for the box lug terminals is 44.3 lb-in (5 N.m) when using the approved 8 to 2 AWG copper or aluminum wire.
Does the QOB250VH feature a visual trip indicator?
Yes, this breaker includes the Square D Visi-Trip indicator. When the breaker trips due to an overcurrent or short circuit, a highly visible red indicator appears in the window to help you quickly identify the tripped circuit.
Can I use the QOB250VH to replace a standard QOB250?
Yes, the QOB250VH shares the same physical dimensions and bolt-on mounting style as the standard QOB250. It can serve as a direct replacement or upgrade when a 22kAIC interrupting rating is required by your system design.
