Square D QOM2150MM Main Circuit Breaker 2 Pole

Square D QOM2150MM is a 150-amp, two-pole main circuit breaker designed for bolt-on installation in Square D QO meter-pak assemblies. It uses the QOM2 frame and is intended for 120/240 VAC service, delivering a 10 kA short-circuit current rating at 240 VAC. Marketed specifically as a main breaker for metering devices, it provides a secure, code‑compliant disconnect point in meter mains and related metering configurations. The bolt-on mounting and 2-pole configuration make it a compact, reliable choice for feeding downstream panels or subfeeds where a dedicated main is required in a two‑pole, 150 A arrangement. As part of the QO family, the QOM2150MM is a recognized main-breaker option within compatible Square D installations, designed to meet standard field-replacement practices in metering equipment. This model is commonly selected when a main disconnect is needed at the meter or within metering assemblies, offering a robust 10 kA interrupting capacity at typical residential or light commercial voltages.
