Product FAQs
6 answersHow many panel spaces does the QO3100VH require?
As a 3-pole QO series breaker, it requires three 3/4-inch spaces in a compatible 3-phase panel.
What does the VH suffix mean in the QO3100VH part number?
The VH suffix designates a high interrupting rating of 22kAIC. This provides a higher fault current rating than the 10kAIC limit found on standard QO circuit breakers without the VH suffix.
Can the QO3100VH be installed in a Square D Homeline load center?
No. Square D QO breakers use a 3/4-inch format that is not physically interchangeable with 1-inch Homeline panels. This breaker must be installed in a QO load center or an NQ/NQOD panelboard.
Can I use this 3-pole breaker in a single-phase residential panel?
No. The QO3100VH is a 3-pole circuit breaker designed strictly for 3-phase systems. It will not safely or correctly land on the bus bars of a single-phase load center.
Does the QO3100VH feature a tripped circuit indicator?
Yes. It includes the Square D Visi-Trip window. When the breaker trips, the handle rests in a center position and a bright red indicator appears in the window to quickly identify the tripped circuit.
Is the QO3100VH HACR rated?
Yes. Standard QO thermal-magnetic circuit breakers are UL listed as HACR type, making them suitable for use with compatible heating, air conditioning, and refrigeration equipment.
