Square D QOM2100VHL Miniature Circuit Breaker

The QOM2100VHL is built on the larger QOM2 frame and is designed to fit 150A, 200A, and 225A convertible QO and Homeline load centers to down-rate the panel to 100A. The QOM100VH uses the smaller QOM1 frame and only fits 100A to 125A load centers. The two frames are physically different and cannot be interchanged.

This QOM2 frame main breaker is exclusively compatible with Square D QO and Homeline convertible main load centers that have a factory mains rating of 150A, 200A, or 225A. It will not fit panels factory-rated for 125A or less.

The "VH" designates a Very High interrupting rating. This breaker is rated for 22kAIC at 120/240VAC, allowing it to be installed in services with higher available fault current than standard 10kAIC main breakers.

It is a bolt-on main breaker that secures directly to the internal bus of a compatible convertible load center using mounting screws. It requires a dedicated QOM2 main breaker footprint and cannot be snapped onto standard branch circuit bus bars.

No, this is a standard thermal-magnetic main breaker designed for primary overcurrent and short-circuit protection. Any required ground-fault (GFCI) or arc-fault (AFCI) protection must be provided by the individual branch circuit breakers installed in the panel.

Yes, both catalog numbers refer to the same 100A QOM2 frame main breaker. The "L" suffix typically indicates that the breaker is factory-packaged with the required wire lugs included.
