## Description

The Shelly Pro 3EM - 120A V2 is a 3-phase energy meter, able to report accumulated energy, instantaneous voltage, current and power factor. With 3 phases, the 3EM - 120A V2 can measure up to 120A per phase and the neutral to within a degree of accuracy of 1%, and can store data in non-volatile memory that can be retrieved for up to 60 days in 1-minute intervals.

The Shelly Pro 3EM 120-A V2 is a WiFi operated DIN-mountable 3-phase energy meter, featuring WiFi, Bluetooth and LAN connectivity for flexible, accurate energy consumption reporting. This device also supports connectivity over the Matter protocol, allowing for integration seamlessly across Apple Home, Google Home, and Alexa for fast, hub-free local control. The Shelly Pro 3EM can be used to monitor any home appliances, electric circuits and office equipment individually, able to monitor 120A per each of its three phases with the help of the three included 120A clamps.
The Pro 3EM supports MODBUS, allowing for quick and seamless deployment in pre-existing installations, and can monitor 2-way energy consumption - energy that's both produced and used - for each of its three phases, ideal for monitoring installations that include renewable energy sources like wind turbines or solar panels.

Also available is the Shelly Pro 3EM 400A, a variant of the Pro 3EM that can measure up to 400A for each
