Eaton 37MM240R1240C49 Commercial Meter Stack - UL Listed

Designed for commercial power distribution, the Eaton 37MM240R1240C49 meter stack supports a 400A service with space for a second 200A section and 208Y/120V outputs. It provides two sockets and a 400A socket in a single, compact footprint, enabling efficient metering of multi-branch loads. This integration reduces panel clutter, simplifies wiring, and speeds up commissioning for retail, office campuses, and light industrial facilities. With a ringless cover and lever bypass, maintenance becomes safer and faster, minimizing outage windows during service work. The design supports quick access to breakers and metering adapters without compromising enclosure integrity. For engineers, this means fewer field modifications and a smoother upgrade path as facility loads change. The meter stack includes factory A-B phase balance and seven-jaws for reliable phase distribution, improving energy accuracy and simplifying troubleshooting during commissioning and routine testing. The unit uses copper bus for low resistance and an aluminum 1200A bus arrangement for higher-density installations, accommodating future expansion, and is compatible with standard Eaton metering accessories and breakers, enabling straightforward retrofits and stock-ready replacements. With dimensions of 66.625 in length, 8.75 in height, and 19.375 in width, and weighing 320 lb, installation fits into medium-size switchgear while providing ample space for conductors and connectors. Overall, the combination of safety features, robust conductors, and a compact footprint supports faster projects, reduced material costs, and improved uptime across commercial sites.
