Product FAQs
6 answersWhat panelboards are compatible with the QOB115VH circuit breaker?
The QOB115VH is a bolt-on circuit breaker designed exclusively for use in Square D NQ and NQOD series panelboards. It cannot be used in standard QO load centers, which require plug-on breakers.
What does the VH signify in the QOB115VH catalog number?
The VH suffix indicates a Very High interrupting rating of 22kAIC at 120/240VAC. This provides higher fault current protection compared to the standard QOB115, which features a 10kAIC rating.
Is the QOB115VH rated for switching fluorescent lighting and HVAC equipment?
Yes, this breaker is both SWD (Switching Duty) rated for 120V fluorescent lighting applications and HACR rated for use with heating, air conditioning, and refrigeration equipment.
Is there a plug-on equivalent to the QOB115VH?
Yes. If you need a plug-on breaker with the same 15A capacity and 22kAIC rating for a standard QO load center, the direct equivalent is the QO115VH.
What is the recommended terminal torque for the QOB115VH?
The pressure plate terminals on this breaker are rated for 14 to 8 AWG aluminum or copper wire and require a tightening torque of 40.7 lb-in (4.6 N.m). Always verify exact torque requirements on the physical breaker label prior to installation.
Does the QOB115VH feature a tripped circuit indicator?
Yes, it includes the Square D Visi-Trip indicator. When the breaker trips, a highly visible red indicator appears in a window on the face of the breaker, allowing for rapid fault identification in a crowded panelboard.
