Shelly Pro 3EM 120A - WiFi Energy Meter

The Shelly Pro 3EM is a versatile DIN rail mountable three-phase energy meter perfect for measuring energy consumption in your home. This smart energy meter offers real-time reports of accumulated energy consumption, voltage, current and power factor per phase.

Complete with 3 CT clamps rated at 120A, the Shelly energy meter offers 1% measurement accuracy.

Bidirectional measurement, consumption and generation

With a storage period of 60 days and a minute-by-minute progression per phase, you will always have a detailed view of your energy consumption. The Shelly Pro 3EM is versatile and can measure both energy consumption and generation using, for example, solar panels. Furthermore, this energy meter can be integrated into existing MODBUS installations and expanded with the Shelly plugin to obtain additional functions, such as humidity or temperature measurement in technical rooms. Supplementing with the Shelly Pro 3EM Switch Add-On ensures that switching functionality can be achieved.

Although the Pro 3EM itself cannot switch, the measurements it takes can be used as input for scenarios where other Shelly devices are controlled.
