Product FAQs
9 answersCan I install this 125A main breaker in a 150A, 200A, or 225A Square D panel?
Yes. The QOM2125VH fits QOM2 frame load centers and CSEDs, which are typically rated from 150A to 225A. It serves as a field installable replacement or downsize option for panels that accept QOM2 mains.
Does the QOM2125VH work in both QO and Homeline panels?
Yes, this main circuit breaker is cross compatible with both Square D QO and Homeline load centers, provided the panel is designed to accept a QOM2 frame main breaker.
Can this breaker replace a main breaker in a QOM1 frame panel?
No. The QOM2125VH is exclusively for QOM2 frame load centers. QOM1 frame panels require a different physical breaker and cannot accommodate the larger QOM2 footprint.
What does the VH suffix mean in the QOM2125VH catalog number?
The VH suffix indicates a high interrupting rating of 22,000 AIC (22kA) at 120/240V. Standard QOM2 main breakers without the VH suffix are typically rated for 10kAIC.
What does the LI trip function on this breaker indicate?
LI stands for Long Time and Instantaneous trip functions. The Long Time function protects against sustained overloads, while the Instantaneous function trips the breaker immediately during a severe short circuit.
What is the recommended tightening torque for the wire terminals on the QOM2125VH?
According to Square D specifications, the main wire lugs should be torqued to 250 lb-in (28 N.m) when using 4 AWG to 300 kcmil aluminum or copper wire.
How is the QOM2125VH mounted into the load center?
This is a bolt-on main breaker. It secures directly to the panel bus with retaining nuts or bolts, providing a permanent and secure connection designed specifically for main service feeds.
Do I need a retaining kit when using this as a main breaker?
No. Because the QOM2 frame bolts directly to the internal bus bar of the load center, it does not require a separate backfed retaining clip like plug-on branch breakers do when used as mains.
Does this breaker provide arc fault or ground fault protection?
No, the QOM2125VH is a standard thermal magnetic main breaker. It provides overload and short circuit protection but does not include AFCI or GFCI circuitry.
