Eaton 3MM612R12RLC Meter Stack - Outdoor UL Listed

Multiple metering design consolidates several circuits in one enclosure, reducing hardware clutter and simplifying load tracking. This yields clear business benefits by shrinking installation time and minimizing outdoor footprint, lowering labor costs and site complexity. It is ideal for multi-tenant buildings and light-commercial projects where accurate metering drives billing clarity and energy management. With a 125A socket and a 1200A bus, the unit delivers robust service capability and safer fault isolation. The impact is safer protection schemes and scalable headroom for future growth, while technicians benefit from defined wiring paths and reduced risk of mis-wiring. In practice, this stack supports three-phase in and single-phase out configurations for diverse feeder layouts. An outdoor-rated, ringless enclosure with no bypass enhances reliability in adverse conditions. This design supports easier utility inspections and compliant installation in exposed environments. It's well matched to outdoor meter stacks for residential and light-commercial deployments. Compatibility with Eaton MCBs—such as A-B, BR2_, BRH2_, BRHH2_, and BRX2—simplifies protection strategy without stocking mismatched parts. The fifth jaw included at the 9 o’clock position adds capacity without rework, improving adaptability. Installers can tailor protection by selecting the appropriate MCBs for each circuit inside the stack. Warranty coverage and UL Listed certification reduce procurement risk and maintenance surprises. Eaton's policy offers one year from installation or eighteen months from shipment, whichever comes first. This translates to lower total cost of ownership and predictable service life for fielded metering systems.
