Hager ECR382D 3-fase directe aansluiting energiemeter 80A 4 modules Modbus MID

The Hager ECR382D is a high-precision three-phase direct connected energy meter designed for commercial and industrial applications. With a maximum current of 80A and MID certification (Module B + D), it ensures accurate billing-grade measurement of active and reactive energy. The device features a Modbus RTU (RS485) communication interface for easy integration into building management systems, along with two configurable S0 pulse outputs. Its compact 4-module DIN rail housing (72 mm) fits standard distribution boards, and the backlit LCD display provides clear readout of all measured parameters including voltage, current, power, frequency, and power factor. Bi-directional energy measurement supports both import and export monitoring.

Advantages

MID certified for legal metrology, Class B accuracy (EN 50470-3) for active energy, direct connection up to 80A without external transformers, Modbus RTU communication for remote monitoring, and bi-directional measurement for renewable energy applications.
