Leviton 4KUMR-R12 Indoor Series 4000 Submeter, DIN Rail Mount, Universal Voltage, 3 Phase 3 Wire/4 Wire, 50A-5000A, (3) 12" Rogowski Current Transformers, Electric Meter Kit

Optimize facility power management with the Leviton Series 4000 indoor submeter — a compact, DIN-rail mounted solution built for accurate energy monitoring and revenue-grade metering. This Leviton submeter kit supports universal voltage 3-phase 3W/4W systems and ships with three 12" Rogowski current transformers (50A–5000A), making it ideal for retrofit jobs, irregular conductor runs, and high-current distribution panels. With ANSI C12.20 Class 0.2% accuracy and IEC-approved performance, the Series 4000 delivers trustworthy kWh measurements for billing, sustainability reporting, and energy optimization. Built-in Modbus RTU (RS-485) enables direct integration with building management systems, security and surveillance power monitoring, and industrial automation platforms. Additional features such as configurable phase-loss alarms, user-enabled password protection, and a bright backlit LCD provide on-site visibility and protection against tampering. Designed for commercial buildings, data centers, solar monitoring, and critical security installations, the Leviton 4KUMR-R12 is a practical, space-saving choice for professional power metering.
