Why Choose the ABB M4M 20 Network Analyzer?

The ABB M4M 20, order code 2CSG251151R4051, is a compact and highly capable three-phase network analyzer designed for accurate electrical parameter monitoring, energy measurement and basic power quality analysis in commercial and industrial electrical systems. As part of the ABB M4M 20 network analyzer series, it provides comprehensive metering functionality for electrical distribution panels, switchboards and energy management applications.

The M4M 20 combines accurate electrical measurement with integrated Bluetooth Low Energy (BLE) connectivity for smart commissioning and configuration. A graphic colour display provides clear visualisation of measured parameters, while two digital outputs support signalling and pulse output applications. This standard M4M 20 model is particularly suitable where local measurement and Bluetooth connectivity are required without an additional wired communication protocol.

Designed for three-phase electrical systems, the analyzer provides a 50–400 V voltage measurement range, supports transformer-connected current measurement with a 5 A rated current input, and operates from a wide-range 48–240 V AC/DC auxiliary supply. With active energy accuracy of ±0.5%, the M4M 20 provides dependable monitoring for industrial power distribution and energy efficiency applications.
