Square D QO2125VH Miniature Circuit Breaker

This breaker fits Square D QO load centers, NQ panelboards, and legacy NQOD panelboards. Always verify your panel's wiring diagram prior to installation, as the specific branch positions used must be rated to accept a 125A plug-on circuit.

No. Square D QO and Homeline (HOM) are separate platforms with entirely different bus attachment styles. This plug-on breaker is designed exclusively for QO-format panelboards.

It requires two standard 3/4-inch QO panel spaces, utilizing a total width of 1.5 inches on the panel bus.

The "VH" designates a high interrupting rating of 22,000 AIC (22 kA) at 120/240V. This is necessary in electrical systems where the available fault current exceeds the 10 kA capacity of standard QO breakers.

Yes. The QO2125VH has the exact same physical dimensions and mounting profile as the standard QO2125. It serves as a direct replacement while providing a higher 22 kA interrupting capacity.

Yes. It includes the Square D Visi-Trip visual indicator. When the breaker trips due to an overcurrent or short-circuit event, a bright red flag drops into the viewing window so you can instantly identify the tripped circuit.

Because it is a standard-rated thermal-magnetic circuit breaker, the National Electrical Code (NEC) limits continuous loads (lasting three hours or more) to 80% of its total rating, which equals 100 amps.

No. This model provides standard thermal-magnetic overload and short-circuit protection only. It does not include AFCI (Arc-Fault Circuit Interrupter) or GFCI (Ground-Fault Circuit Interrupter) functionality.
