Leviton 4KUMR-R Indoor Series 4000 Submeter, DIN Rail Mount, Universal Voltage, 3 Phase 3 Wire/4 Wire, Modbus RTU, Electric Meter, USE Rogowski CTs

Designed to deliver reliable, enterprise-grade power monitoring, the Leviton 4KUMR-R Indoor Series 4000 submeter provides precise 3-phase energy measurement for facilities, data centers, and security/surveillance installations. This submeter supports universal voltage 3-phase 3W/4W configurations and pairs with Rogowski CTs to capture accurate current profiles while maintaining ANSI 0.2% (IEC 0.5S) accuracy for billing-grade and energy-management applications. DIN-rail mounting simplifies installation in panels and switchgear, and Modbus RTU (RS-485) connectivity enables real-time integration with building management systems, SCADA, and power monitoring software. Built-in features such as bidirectional measurement for renewable energy flows, phase-loss alarm outputs, user-enabled password protection, and a bright backlit LCD make the 4KUMR-R ideal for critical infrastructure where uptime and secure monitoring matter. Certified for CSI, UL rated, and CE compliant, this Leviton electric meter supports compliance and long-term reliability. Add the 4KUMR-R to your power monitoring strategy to improve energy visibility, support renewable integration, and protect equipment in security and surveillance environments.
