The ABB M1M 15 is a digital electrical power meter designed for monitoring electrical systems and measuring energy consumption. It provides measurements of key electrical parameters and is suitable for applications such as electrical distribution panels, switchboards, industrial installations and energy cost allocation.

The meter features a red LED display, front-panel mounting and current transformer (CT) inputs rated at 1 A or 5 A. It operates with an auxiliary supply of 100–230 V AC/DC and supports active-energy measurement accuracy of ±1%. This specific ordering code is the standard M1M 15 model; the separately listed M1M 15 Modbus version is available for applications requiring communication with supervisory or automation systems.
