Eaton Specification Sheet - 3MM512C2BC
Multi-metering integration reduces panel footprint and labor by consolidating measurements into a single enclosure, supporting residential and light-commercial scenarios. Business impact: faster commissioning, fewer field wiring errors, and improved energy accountability in multi-tenant buildings. Application: ideal for shared utility meters, sub-feed panels, and retrofit projects where space is at a premium and accuracy is critical. 125A service with an 800A copper bus delivers robust headroom for future expansion, translating to longer system life and deferred utility upgrades. Business impact: reduced capital expenditure and smoother capacity planning. Application: new installations and upgrades in compact electrical rooms. Five-jaw sockets and five connection points streamline wiring, reducing installation time and increasing reliability. Business impact: fewer mis-wired connections and improved metering stability. Application: mixed-load residential or light-commercial feeders. Three-phase in, single-phase out configuration supports common load profiles without sacrificing measurement granularity. Business impact: simpler protection coordination and better load management. Application: dedicated multi-feed panels. Indoor-only design protects critical components from the elements, aiding longevity and reducing service calls. Business impact: lower operating costs and predictable maintenance. Application: indoor meter enclosures in basements, mechanical rooms, or utility closets. Warranty and support: one-year from installation or eighteen months from shipment, with Eaton’s standard service policies providing reassurance for long-term operations. Application: asset protection and lifecycle planning in regulated environments.

FAQs
The Eaton 3MM512C2BC is designed for indoor residential and light-commercial panel installations requiring multi-metering. It supports multiple meters in a single enclosure, reducing cabinet space and simplifying wiring. Ideal for multi-tenant buildings or separate feeders within a single facility, it helps maintain accurate energy accounting while streamlining commissioning and maintenance tasks.
This meter stack provides multiple metering points with five-jaw sockets and five connection points. It supports a configuration of three-phase in and single-phase out, with a copper bus rated for 800A and a service rating of 125A. This arrangement accommodates separate phase measurement for diverse loads while maintaining straightforward wiring and protection coordination.
Compatibility depends on the MCBs selected by the installer. The unit is designed to work with Eaton MCBs and can be configured to match protective devices for each metering channel. Consult Eaton’s specification sheet to verify precise MCB compatibility and to ensure the chosen breakers align with the meter stack’s rated current, bus, and allowable fault levels.
The 3MM512C2BC is UL Listed, signifying compliance with recognized electrical safety standards for enclosure-based metering. For project teams, UL Listing provides a clear baseline for safe integration into existing electrical rooms and ensures compatibility with standard utility and code requirements. Always cross-check local codes and utility requirements when deploying multi-meter stacks in commercial or residential settings.
Key dimensions include a length/depth of 12.26 inches, height of 57.5 inches, and width of 7.01 inches, with a weight of approximately 75 pounds. These metrics help engineers plan cabinet space, clearance, and mounting considerations in restricted electrical rooms. Ensure adequate footprint and access for maintenance, wiring, and future metering upgrades.
