Eaton Specification Sheet - 3MM612RC
Multiple metering capability enables precise monitoring of separate loads within a single service. This drives accurate energy accounting, tenant billing, and better demand management for multifamily and mixed-use developments. The design supports non-residential sub-metering while preserving circuit-level visibility for each tenant. Outdoor-rated enclosure design improves durability in exterior environments and reduces maintenance trips. Combined with copper conductors and robust bus ratings, it withstands weather exposure and high-energy demand, translating to fewer service interruptions and longer intervals between replacements. The 125A main with an 800A bus provides substantial headroom for growing loads without reconfiguration, minimizing retrofit costs and helping future-proof installations for aging buildings or new multi-tenant builds. Five-jaw sockets and the three-phase in, single-phase out configuration deliver flexible metering for diverse feeders. Electricians can tailor configurations to tenant loads, select MCBs, and consolidate metering hardware, reducing inventory variety. UL Listed certification and Eaton warranty terms add risk management value, with the 25-000 policy reflecting safety and reliability expectations while the warranty lowers total cost of ownership. Compatibility with Eaton metering products and standard wiring practices simplifies installation, lowers training requirements, and accelerates project timelines. Installation compatibility with sockets:6 and a five-jaw design ensures simple MCB integration, supporting a range of common residential and light commercial metering scenarios. In the broader industry context, the 3MM612RC delivers clean measurement data essential for submetering analytics, billing, and demand response programs.

FAQs
Ensure the enclosure is outdoor-rated and sized for the 66.5 in height and 12.26 in depth. Verify space for six sockets with five-jaw connections, and confirm compatibility with three-phase in, single-phase out configurations at 120/208 VAC. Use suitable MCBs that match the 125A main and 800A bus to maintain rating integrity.
The unit provides multiple metering channels within a single stack, enabling separate usage data per tenant or circuit. Its six sockets and flexible 3-phase in, 1-phase out configuration simplify sub-metering without adding separate panels, reducing space, wiring, and installation time while improving billing accuracy and energy management.
Yes, the 3MM612RC is UL Listed, confirming adherence to safety standards for electrical equipment. It carries Eaton’s warranty policy, which specifies one year from installation or eighteen months from shipment, whichever comes first, offering protection against manufacturing defects during the coverage period.
Key specs include a 125A main rating, 800A bus rating, copper construction, sockets: six with five-jaw design, outdoor enclosure, and a 120/208 VAC operating voltage. The configuration supports three-phase in and single-phase out, enabling versatile feeder arrangements for multi-tenant or mixed-use applications.
The stack minimizes field labor with plug-and-play MCB compatibility and reduces space and wiring complexity, accelerating deployment. Its outdoor durability lowers maintenance frequency, while the UL Listed certification provides compliance confidence, helping reduce project risk and improve total cost of ownership over the system’s life cycle.
