Why Choose the ABB M4M 30 Rogowski Network Analyser?
The ABB M4M 30 Rogowski is an advanced three-phase network analyser and power-quality meter designed for detailed electrical measurement, energy-efficiency monitoring and power-quality analysis in industrial and commercial installations. As part of the ABB M4M 30 panel-mounted meter series, it combines comprehensive electrical measurements with an intuitive colour touchscreen, communications and flexible monitoring functions.
This version is specifically designed for use with ABB R4M Rogowski coils, providing a flexible current-measurement solution that is particularly useful for retrofit installations. The M4M 30 Rogowski provides four Rogowski coil inputs and can be used with ABB R4M-80 and R4M-200 coils, allowing current measurement to be added around existing conductors with minimal disruption to the electrical installation.
The analyser supports Modbus RTU via RS485 and Bluetooth communication and includes four programmable I/O. With a 48–240 V AC/DC auxiliary supply, 96 × 96 mm front-panel format and extensive measurement of voltage, current, power, energy, power factor, frequency, harmonics and other power-quality parameters, it provides a versatile monitoring platform for modern electrical distribution systems.

Comprehensive Power and Energy Monitoring
The ABB M4M 30 Rogowski provides detailed visibility of an electrical network by measuring fundamental quantities including voltage, current, frequency, power factor, active power, reactive power, apparent power and energy. Advanced functions such as harmonic analysis, THD measurement, waveform capture and phasor diagrams help engineers identify power-quality issues and evaluate electrical-system performance.
Rogowski-coil technology is particularly valuable when monitoring existing installations because the flexible coils can be fitted around conductors without the installation constraints associated with conventional closed-core current transformers. Combined with Modbus RTU, Bluetooth and programmable I/O, the M4M 30 Rogowski provides a flexible platform for energy-management, power-quality and electrical-distribution monitoring systems.
Typical Applications
- Industrial electrical distribution systems.
- Commercial building energy monitoring.
- Power-quality analysis and troubleshooting.
- Energy-efficiency monitoring and optimisation.
- Retrofit metering of existing electrical installations.
- Main and sub-distribution switchboards.
- Industrial machinery and production facilities.
- Building-management and energy-management systems.
