Eaton 37MM140R1240300 Commercial Meter Stack - UL Listed
Part Number: 37MM140R1240300
Quick Summary
The Eaton commercial meter stack is a reliable power distribution solution for commercial and light-industrial facilities. Engineers often struggle with space constraints, maintenance access, and metering security in centralized electrical spaces. UL Listed certification and regional utility approvals support code compliance and field acceptance, while compact aluminum bus and three-phase in/out designs streamline installation. For procurement teams, a scalable 400A stack with a 1200A bus rating helps reduce downtime and long-term operating costs, empowering faster project delivery and predictable ROI across multi-tenant environments. This solution also aligns with availability and serviceability needs in data centers, retail complexes, and campus-wide electrical systems, where dependable metering is non-negotiable.

Selling Policy 25-000 - Distribution and Control Products and Services
Feature → Business Impact → Application: The meter stack uses seven jaws and a 400A service with a 1200A aluminum bus, delivering robust mechanical strength and capable load handling for busy facilities. This translates to improved reliability, reduced conductor overheating risk, and lower maintenance intervals, especially in high-uptime environments like offices and shopping centers. Application: Ideal for commercial campuses and multi-tenant buildings requiring solid three-phase distribution and secure metering, with installation efficiency that accelerates project timelines. Feature → Business Impact → Application: Three-phase in/out configuration enables balanced loads and straightforward expansion as demand grows, supporting compliant distribution in new builds and retrofits. Application: Data centers and light-industrial plants benefit from scalable metering that minimizes wiring complexity while maintaining critical power availability. Feature → Business Impact → Application: Lever bypass and ringless security reduce maintenance disruptions and deter tampering, improving safety and uptime during servicing. Application: Retail centers and campuses where physical security and quick restore of service are essential. Feature → Business Impact → Application: Factory A-B phase balance aids utility-grade performance and more accurate kilowatt-hour measurements, helping facilities meet regulatory expectations. Application: Utility and campus installations with stringent metering accuracy requirements. Feature → Business Impact → Application: 208Y/120V capability accommodates common commercial loads, enabling straightforward integration with standard panel voltages. Application: Office buildings, schools, and healthcare facilities using typical commercial gear. Feature → Business Impact → Application: UL Listed certification and regional utility approvals streamline permitting and acceptance, reducing project risk and accelerating commissioning. Application: New constructions and major upgrade projects targeting code compliance. Warranty and service terms provide financial protection; a one-year warranty from installation or eighteen months from shipment minimizes lifecycle risk and supports total cost of ownership goals.

FAQs
This meter stack is designed for three-phase in/out operation at 208Y/120V. When integrating with existing panels, confirm space for a 52.63 in tall enclosure and 18.25 in width, ensure adequate clearance for wiring and bypass lever access, and verify compatibility with aluminum bus conductors rated to 1200A. Plan for secure mounting, ringless security, and alignment with First Energy (utility) approved configurations to streamline permitting and field acceptance.
The product is UL Listed, which supports code compliance and safety verification. It also lists utility approvals across multiple territories (First Energy regions such as Potomac Edison and others). These approvals facilitate project acceptance in utility-backed installations and can shorten the interconnection and commissioning process in eligible states.
Yes. The design supports three-phase in/out with a 400A service and 1200A aluminum bus, providing robust distribution for high-density loads. Features like seven-jaws, lever bypass, and factory A-B phase balance contribute to reliable metering and quick maintenance, while UL Listed certification aids compliance in regulated environments typical of data centers and multi-tenant campuses.
Warranty terms follow Eaton policy SP25-000: one year from installation or eighteen months from shipment, whichever occurs first. The lever bypass and ringless security design reduce downtime during servicing, and the aluminum bus construction offers long-term durability with fewer maintenance interventions compared to older copper-bus configurations.
The combination of a 400A service with a 1200A bus provides scalable capacity for growth with a single enclosure, reducing future hardware deployments. UL Listed and utility approvals lower risk during procurement and commissioning, while reliable phase balance and secure metering minimize outages and maintenance expenses, delivering faster project completion and lower total cost of ownership.
