Leviton 4OUMR-4M Modbus Submeter Kit, Outdoor, Universal Voltage, 3-Phase 3-4 Wire, 400A, 3 Split Core Current Transformers

Optimize site-wide power visibility with the Leviton 4OUMR-4M Modbus submeter kit — a durable outdoor multimeter solution designed for accurate, revenue-grade energy monitoring. This Leviton submeter combines ANSI C12.20 Class 0.5% accuracy with universal voltage compatibility (90–600V) and three 400A split-core current transformers for fast, non-invasive installation on 3-phase 3- or 4-wire feeds. Housed in a NEMA 4X enclosure, the meter is built for rooftop, outdoor electrical rooms, and industrial environments where reliable performance matters.

Integrated Modbus RTU (RS-485) communications make it straightforward to tie power data into building automation, energy management, and security or surveillance power monitoring platforms. User-enabled password protection, phase-loss alarms, and a bright backlit LCD give technicians the control and visibility needed to reduce downtime and support accurate billing or sub-billing. Ideal for facility managers, integrators, and security system operators who need precise, network-ready metering for critical loads.
