The ABB M1M 20 is a digital electrical power meter designed for monitoring electrical systems and analyzing energy consumption in commercial and industrial applications. It measures key electrical parameters and supports total harmonic distortion (THD) and four-quadrant import/export measurement for basic power-quality analysis, power-factor management and monitoring installations with local energy generation.

The meter features an LCD display, front-panel mounting and current transformer (CT) inputs rated at 1 A or 5 A. Its auxiliary supply operates at 100–230 V AC/DC. With active-energy measurement accuracy of ±1%, it is suitable for electrical distribution panels, switchboards, energy monitoring and electrical system management. This specific version does not include built-in communication or digital inputs/outputs.
