Eaton Specification Sheet - 37MM240R124093
Feature → Business Impact → Application: The meter stack ships with pre-installed breakers (one 200A and one 300A) and lever bypass, which dramatically shortens field wiring and commissioning times, delivering tangible cost savings on project labor and startup. In practice, this means faster street‑level energization for commercial campuses and multi-tenant facilities, reducing outage exposure during commissioning. Feature → Business Impact → Application: A 400A amperage rating paired with a 208Y/120V output supports mainstream low‑voltage metering for three‑phase feeders, enabling accurate demand tracking and energy management without introducing bulky retrofits. This fits mid‑sized data centers, retailers, and office complexes seeking dependable metering with minimal disruption. Feature → Business Impact → Application: Ringless covers, ring‑rated aluminum 1200A bus, and a 66.625 in footprint provide a clean, code‑compliant installation that streamlines cabinet design and reduces service interruptions, especially in retrofit projects. Feature → Business Impact → Application: Seven‑jaw sockets and two sockets across a compact frame support scalable expansion while maintaining service continuity, addressing future growth without replacing the entire stack. Feature → Business Impact → Application: UL Listed certification and Eaton’s warranty reinforce risk mitigation for maintenance teams and procurement, delivering predictable uptime and protection against unplanned capital expenditure. Feature → Business Impact → Application: High‑density metering for commercial power management aligns with energy‑efficiency initiatives, enabling precise load profiling and chargeback across tenants and departments.
