Square D QOM2100MM is a 100 A, 2-pole molded-case main breaker in the QOM2 family, designed for bolt-on installation in meter mains and other Square D enclosures. It provides 120/240 V AC operation and a 10 kA interrupting rating, suitable as the main disconnect for metering-device applications. This model is explicitly described as a main breaker for metering devices and uses the QOM2 frame for bolt-on mounting; it is not a plug-on unit and requires a compatible enclosure.
