Three-phase digital electricity energy meter RLE03-4M - MID, CE, 63A, RS485, ModBus, four-quadrant 2617213

Three-phase energy meter – precise measurement and remote monitoring

This RLE03-4M three-phase energy meter is an advanced measuring device designed for accurate billing of energy consumption in three-phase (3P4W) installations with a voltage of 3(N)~ 400/230 V AC. The MID certificate guarantees compliance with European accuracy standards, enabling use in official billing, both in the industrial and commercial sectors. The device is particularly recommended for photovoltaic installations due to its bidirectional energy measurement.

Functionality and communication

The RLE03-4M meter offers comprehensive measurement of electrical parameters, including voltage, current, active, reactive and apparent power, power factor and frequency. Equipped with an RS-485 communication interface with Modbus RTU protocol, it enables easy integration with energy management systems (EMS) and SCADA systems. Remote data reading allows for effective monitoring and optimization of energy consumption. Additionally, it has a pulse output for cooperation with technical balancing systems.

Installation and application

The compact housing (width 72 mm) facilitates mounting on a 35 mm rail according to PN-EN 60715. The meter is designed for direct connection (up to 63A), eliminating the need for additional current transformers in many applications. It will be useful in industrial plants, shopping centers, public utility buildings and photovoltaic installations. Compliance with PN-EN 50470 ensures reliable operation in various environmental conditions. The device has an IP20 housing (panel IP51).
