Product FAQs
9 answersWhat type of load center is required for the QO120VHPAFGF?
This breaker is designed exclusively for Square D QO Plug-On Neutral load centers. It will not fit Homeline panels or older QO panels that lack a plug-on neutral bar.
Can I install this QO breaker in a Square D Homeline panel?
No. QO series breakers have a different mounting footprint and are not interchangeable with Homeline load centers.
What does the VH designation mean in the QO120VHPAFGF part number?
The VH indicates a higher interrupting rating of 22kAIC at 120VAC. Standard QO breakers without the VH designation typically have a 10kAIC rating.
What level of ground fault protection does this dual-function breaker provide?
It provides Class A ground fault protection, which is designed to trip when a fault current to ground reaches 6mA or more, ensuring personnel safety.
What wire sizes are compatible with the terminals on this breaker?
The pressure plate terminals accept 14 AWG to 8 AWG aluminum or copper conductors.
What is the difference between the QO120VHPDF and the QO120VHPAFGF?
The QO120VHPAFGF is the direct, updated replacement for the obsolete QO120VHPDF. Both are 20A, 1-pole, 22kAIC dual-function breakers designed for QO Plug-On Neutral load centers.
Is there a 10kAIC version of this dual-function breaker available?
Yes. If your electrical system only requires a 10kAIC interrupting rating, you can use the standard QO120PAFGF model instead of the 22kAIC VH version.
What type of faults does the QO120VHPAFGF protect against?
As a dual-function breaker, it provides thermal-magnetic protection against overloads and short circuits, plus electronic protection against both series and parallel arcing, and Class A ground faults.
Does this breaker feature a tripped status indicator?
Yes, like most Square D QO breakers, it includes a Visi-Trip indicator that provides a clear visual confirmation when the breaker has tripped.
