Square D QOM2125MVH Miniature Circuit Breaker

This breaker is specifically designed for use as a tenant main breaker in Square D MP Meter-Pak Meter Centers and EZ Meter-Pak Metering Equipment.

While both are 125A, 2-pole, 22kAIC breakers in the QOM2 frame size, their applications differ. The QOM2125VH is used as a main breaker in standard QO and Homeline load centers. The QOM2125MVH is engineered specifically for group metering applications like MP and EZ Meter-Pak enclosures.

No. Although it is part of the QO family, the M in the MVH suffix indicates it is designed for Meter-Pak metering centers. For a standard QO or Homeline load center requiring a 125A QOM2 main breaker, you should use the QOM2125VH instead.

The VH designates a Very High interrupting rating. It signifies that the breaker can safely interrupt up to 22,000 amps (22kAIC) of fault current at 120/240VAC, compared to the standard 10kAIC rating found on models with an MM suffix.

This breaker features the Square D Visi-Trip indicator. When a fault causes the breaker to trip, the handle moves to a center position and a bright red flag appears in the indicator window, allowing you to quickly identify the tripped circuit without guessing.

Yes, the QOM2125MVH is HACR rated. This means it has been tested and approved for use with heating, air conditioning, and refrigeration equipment requiring group motor protection.

It utilizes a fixed thermal-magnetic trip mechanism. The thermal component provides long-time protection against mild overloads, while the magnetic component provides instantaneous protection against severe short circuits.
