Square D QOM2200MM Miniature Circuit Breaker

The QOM2200MM has a standard short-circuit interrupting rating of 10kAIC. The QOM2200MVH is the higher-rated version, offering a 22kAIC interrupting rating for applications requiring higher fault current protection. Both share the same physical footprint for Meter-Pak equipment.

No. The lug orientation is different between the QOM2-VH and QOM2-MM breakers. The QOM2200VH is designed for standard QO load centers and will not fit properly in Meter-Pak metering equipment.

While it shares the QOM2 frame size, this breaker features a specific lug orientation designed for MP Meter-Pak meter centers. For standard QO or Homeline load centers requiring a 200A main breaker, the QOM2200VH is typically required.

This main breaker is specifically designed for use in Square D MP Meter-Pak meter centers and compatible centralized metering equipment to serve as a tenant disconnect.

It utilizes a bolt-on mounting style, which provides a secure, high-capacity connection to the distribution bus in commercial and multi-family metering setups.

This breaker comes equipped with factory-installed box lugs that accept either copper or aluminum conductors ranging from 4 AWG up to 300 kcmil, making it suitable for standard 200A service feeds.

The breaker uses a fixed Long-Time (L) function to prevent overheating from sustained overloads, combined with an Instantaneous (I) function that trips immediately during severe short circuits to protect the metering equipment.
