Shelly 3EM is a three-phase wireless relay that monitors energy consumption.
The ideal solution for automating non-smart devices.
It monitors the individual consumption of household appliances, electrical circuits and office equipment (lights, power lines, security systems, heating and cooling, etc.). The consumption of the whole house or the electricity generated by solar panels.
Shelly 3EM is Shelly's professional three-phase power meter, recommended for both home and business use. Shelly 3ЕМ can monitor power consumption in real time for a three-phase or 3-point system or a single-phase electrical system simultaneously (up to 120A each). With Shelly 3EM you can also measure how much energy your solar system is producing and energy consumption at the same time. It can also be used to monitor power consumption in real time for each phase and compare it to the neutral to know if someone is stealing electricity.
It can automatically shut down the entire circuit if consumption or energy (prepaid energy option) reaches the set limit and has integrated relay output for contactor control.
