Leviton 41OUM-R18 Submeter Outdoor Universal Voltage 3-Phase 3-Wire / 4-Wire, 18" Rogowski Current Transformers Not Included, Electric Meter

Optimize energy visibility for commercial, industrial and renewable installations with the Leviton 41OUM-R18 submeter. This outdoor bidirectional electric meter lets you track power imported from the grid and exported from on-site generation—ideal for solar, wind and tenant cost allocation. Engineered as a 3-phase 3-wire/4-wire universal-voltage meter (90–600VAC), the Series 4100 supports common site voltages including 347VAC and 600VAC L-L, reducing the need for multiple meter SKUs. Built for harsh environments, the NEMA 4X enclosure and -22–158°F operating range keep monitoring, security and surveillance power systems online. Use Modbus RTU or BACnet MS/TP to feed real-time energy data into BAS/BMS/EMS platforms or security monitoring consoles for proactive asset and load management. The meter accepts 18-inch Rogowski CTs (sold separately) to handle large or irregular conductors without sacrificing accuracy. Specify the Leviton 41OUM-R18 when you need reliable, network-ready energy monitoring for renewable integration, tenant billing, or critical-power surveillance systems. Contact us to configure CTs and integrate the submeter into your energy or security monitoring solution.
