Description

Shelly 3EM is Shelly’s 3-phase professional power meter for recommended for both home and corporate use. Shelly 3ЕМ can monitor energy consumption in real time for a 3-phase system or 3 points or a monophase electrical system simultaneously (up to 120A each). With Shelly EM you can also measure how much energy your solar system produces and the power consumption ath the same time. It can also be used to monitor real-time energy consumption for each phase and compare it to the neutral to know if someone is stealing electricity.

It can automatically turn off the whole circuit if consumption or energy (pre-paid energy option) reaches the set limit and has integrated relay output made for contactor control.
