Eaton Specification Sheet - U1M1R7
Single-meter position design simplifies field wiring, reduces termination errors, and minimizes mis-termination risks during panel assembly. This configuration translates into faster commissioning and lower labor costs on commercial and light-industrial metering projects. It is well suited for commercial and light-industrial distribution panels that require a dedicated main-meter interval and straightforward expansion. UL listing and EUSERC approval represent essential standards, delivering compliance confidence and safer maintenance. The 100 A main and 10 kAIC interrupt rating further reduce fault exposure while supporting reliable service during peak demand. This combination makes it a dependable choice for utility-connected metering and code-driven installations across commercial facilities. Aluminum bus and galvanized steel enclosure with ANSI 61 gray finish deliver rugged durability in harsh environments. The construction resists corrosion and physical wear, extending service life in both surface-mounted and underground installations. Panel builders benefit from consistent dimensional footprint and compatibility with standard Eaton accessories. Compatibility with Eaton B-Line accessories enables flexible mounting, faster retrofits, and standardized field wiring. The design supports straightforward migration from legacy metering setups and reduces field configuration errors. Builders gain predictable lead times and smoother commissioning schedules on projects of any size. From a total cost of ownership perspective, the U1M1R7 delivers lower maintenance costs and longer replacement cycles. Its 120/240 V three-phase rating aligns with common commercial power distributions, improving compatibility with existing feeder layouts. Overall, electricians and panel hosts get a robust, code-compliant metering solution that scales with project demand.
