Eaton 3MM512R12RL Residential Meter Stack - UL Listed

Three-phase in, single-phase out is the defining configuration of this meter stack, enabling compact group metering for multi-tenant facilities. Consolidating meters into a single enclosure reduces field wiring and saves floor space, while making future service upgrades faster and safer. With a ringless security approach and a robust enclosure, installation can proceed without compromising access to individual meters. Application: residential towers, mixed-use developments, and small office campuses that require centralized monitoring without sacrificing individual unit visibility. 125A rating with a 1200A aluminum bus provides substantial headroom for common loads and submetering, reducing the need for frequent panel replacements. This supports phased builds and evolving load profiles, while maintaining a clean, centralized interface for the building’s electric services. The design also facilitates straightforward main breaker integration and predictable maintenance planning. Application: service entrances for new multi-story apartments and light commercial properties seeking predictable energy management. Aluminum bus construction keeps weight manageable while delivering robust conductivity and corrosion resistance. Lighter assemblies reduce install labor and shipping costs, especially on crowded job sites where crane time is limited. The material choice also supports long-term reliability under varied ambient conditions. Application: deployments with limited crane access or stringent weight limits where copper bus solutions are impractical. Five jaws and five sockets support multiple meters in one stack, enabling efficient group metering and straightforward commissioning. The layout minimizes mis-wiring during future upgrades and eases coordination with utility services, procurement, and field crews. The enclosure supports quick adaptation to changing metering requirements without major rewiring. Application: high-meter-count facilities such as multi-dwelling buildings, student housing, and senior living campuses. Indoor/outdoor enclosure and ringless security offer installation flexibility and enhanced protection against tampering. Bypass is None, reinforcing safety and compliance by eliminating bypass paths. UL Listed certification and utility approvals, including GA and TX, streamline interconnection and regulatory acceptance. Application: exterior walls, controlled corridors, or utility rooms where security and environmental exposure are considerations.
