The ABB M1M 30B-02 Modbus is an advanced digital electrical power meter designed for detailed monitoring and analysis of industrial and commercial power distribution systems. It measures electrical parameters and provides power-quality analysis, including harmonic measurement up to the 40th harmonic. These features support demand management, energy optimization, electrical system diagnostics and monitoring of installations with local energy generation.

The meter supports Modbus RTU communication over an RS-485 interface, allowing integration with PLCs, SCADA systems, building management systems and energy-management software. Its Class 0.2 accuracy classification makes it suitable for applications requiring high measurement precision. The M1M 30B series also supports internal data logging for historical analysis and operational monitoring.
