METSEIEM3255 — Schneider iEM3000/EM6400NG Mid-Range Energy Meter
The Schneider Electric iEM3000 series (including the EM6400NG family) is a range of mid-range DIN-rail energy meters delivering class 1 to class 0.5S accuracy with integrated Modbus RTU RS-485 communication, providing active and reactive energy measurement, power factor, harmonics to the 15th order, and demand metering in a 4-module DIN-rail housing. The iEM3255 model within the range provides class 0.5S accuracy per IEC 62053-22, bridging the gap between basic PM1000-class sub-metering and high-end ION7650 power quality metering — making it the preferred instrument for distribution board sub-metering at tenant and departmental level in Saudi commercial buildings, hospital electrical zones, and industrial facility cost centres where energy accountability requires better-than-class-1 accuracy.
The iEM3000 series' standard Modbus RTU register map is compatible with the complete Schneider Acti9 Smartlink ecosystem, allowing iEM3 meters to share the building Modbus RS-485 network with Smartlink circuit breaker monitoring modules — providing both circuit status and energy data over the same 2-wire bus. The built-in two-wire RS-485 interface accepts up to 32 meters on a single Modbus segment, enabling comprehensive sub-metering of every distribution board circuit in a Saudi commercial building without additional network infrastructure. The meter's digital input allows pulse-from-external-meter counting, making it compatible with legacy pulse-output meters in buildings undergoing incremental sub-metering upgrades.
In Saudi Arabia, the iEM3000 series is the most widely installed mid-range energy meter in commercial building sub-metering projects for SGBC Mostadam and LEED certification, providing the class 0.5S accuracy required for the LEED EA Credit prerequisite for minimum energy performance verification. Hospital electrical zone sub-metering mandated by Saudi Ministry of Health technical specifications for medical facility energy management uses iEM3255 meters at the department level to provide ward, theatre, and diagnostic area energy data. NEOM's commercial buildings use iEM3 meters at circuit level to feed city-scale energy consumption data into the EcoStruxure Building Operation platform.
Razz Middle East stocks iEM3000 series meters in class 1 and class 0.5S versions with single-phase and three-phase options. We provide complete sub-metering system design, Modbus network architecture, and BMS integration documentation for commercial building and industrial facility energy management projects across Saudi Arabia.

Key Features & Benefits
- Class 0.5S accuracy per IEC 62053-22 meets LEED EA Credit minimum energy performance verification requirements — one accuracy class higher than the class 1 meters used for basic sub-metering.
- Standard Modbus RTU register map compatible with Acti9 Smartlink allows iEM3 meters to share building Modbus RS-485 bus with circuit breaker monitoring modules, eliminating separate communication infrastructure.
- Harmonics measurement to the 15th order identifies dominant harmonic sources — 3rd, 5th, and 7th — enabling facility engineers to assess IEEE 519 harmonic compliance without a dedicated power quality analyser.
- Demand metering with configurable integration period calculates maximum demand kW and kVA for SEC tariff analysis and capacity planning without additional demand measurement instruments.
- Digital pulse input enables counting pulses from legacy pulse-output meters in buildings undergoing incremental sub-metering upgrades, preserving the existing meter investment.
- Up to 32 meters on a single Modbus RS-485 segment reduces communication infrastructure cost for comprehensive sub-metering of all distribution board circuits in Saudi commercial buildings.
- 4-module DIN width minimises panel space per meter in commercial building distribution boards where multiple iEM3 meters are installed alongside MCBs and SPDs.
Industrial Applications in Saudi Arabia
- SGBC Mostadam and LEED EA Credit sub-metering for commercial buildings in Riyadh, Jeddah, and Dammam, where class 0.5S iEM3255 accuracy satisfies green building energy certification prerequisites.
- Saudi Ministry of Health hospital department-level energy sub-metering, where iEM3 meters provide ward, theatre, and diagnostic area energy data for hospital energy management programmes.
- NEOM commercial building circuit-level energy metering integrated with EcoStruxure Building Operation via Smartlink Modbus bus, feeding city-scale energy data into NEOM's digital twin platform.
- Industrial facility cost centre energy sub-metering at ARAMCO and SABIC plants, where iEM3 demand metering supports ISO 50001 energy performance monitoring and departmental cost allocation.
- Commercial building tenant sub-metering in multi-tenant office and retail developments, where class 0.5S accuracy provides legally defensible energy billing for landlord-tenant electricity allocation.
- Saudi university campus building-level energy metering under institutional energy management programmes at KFUPM, KAUST, and King Saud University, supporting carbon footprint measurement.
- Hotel and hospitality venue operational area sub-metering at Saudi five-star hotels, where iEM3 meters provide kitchen, laundry, HVAC, and guest room area energy consumption data for operational efficiency analysis.
