Product FAQs
5 answersWhat panelboards are compatible with the QOB120VHCAFI?
This bolt-on breaker is designed for use in Square D NQ and legacy NQOD panelboards. It will not fit in standard QO load centers, which require plug-on breakers.
What does the VH designation indicate on this breaker?
The VH suffix denotes a higher interrupting rating of 22kAIC at 120V, compared to the standard 10kAIC rating found on standard QOB breakers.
Does the QOB120VHCAFI feature a pigtail or plug-on neutral?
This model features a standard pigtail neutral. The coiled white wire must be routed and terminated directly to the panel neutral bus bar to power the internal AFCI circuitry.
What level of arc fault protection does the CAFI designation provide?
CAFI stands for Combination Arc Fault Circuit Interrupter. It provides protection against both parallel arcs (line-to-neutral or line-to-ground) and series arcs (loose connections within a single conductor) to meet NEC requirements for branch circuits.
Is this a direct replacement for the standard QOB120CAFI?
Yes, it can replace a standard QOB120CAFI. The VH version provides a higher 22kAIC interrupting rating, making it suitable for systems with higher available fault current while maintaining the same physical footprint and AFCI functionality.
