Leviton 4DUMR-R 4100 Submeter, Indoor, DIN Rail Mount, 90-600VAC, Modbus RTU, BACNet/MS/TP, USE Rogowski CTs

Optimize facility power visibility and renewable energy tracking with the Leviton 4100 Submeter. This DIN-rail multimeter is built for building managers, integrators, and security teams who need reliable, high-resolution energy monitoring for solar PV, backup systems, and critical surveillance infrastructure. Rated for 90–600 VAC, the 4100 supports Rogowski CTs for flexible current sensing and delivers ANSI 12.20 0.2% / IEC 0.2S accuracy to reduce billing disputes and improve performance reporting. With native Modbus RTU and BACnet MS/TP communications, the meter plugs into existing BMS and networking environments for centralized data collection and fault detection. Installation is straightforward thanks to the compact DIN-rail form factor and optional NEMA 4X enclosure for harsher locations. Security-conscious sites benefit from user-enabled password protection and a bright, backlit LCD for local diagnostics. Use the Leviton 4100 Submeter to monitor energy flows for building management, power resilience of surveillance systems, or revenue-grade solar export tracking. Add it to your panel or contact our sales team to specify the meter for your next project.
