Why Shelly 3em?
Smart 3-Phase Energy Meter with Contactor Control
Many appliances, homes, and buildings use more energy than they need, leading to energy waste and higher spending. Shelly 3EM is a smart 3-phase professional energy meter that will help monitor electricity usage in real-time and get notified in case an appliance or system consumes power above a pre-set threshold. Additionally, it allows for contactor control Smart energy metering will help you identify and eliminate any redundant energy consumption.
Connect Shelly EM to your Wi-Fi network. No HUB required!
Shelly ЕМ monitors monophase electrical systems with up to 3 points simultaneously.
Shelly EM has an integrated 10A relay output for contactor control.
The measurements from Shelly EM are stored in a free cloud for 365 days.
Set custom schedules based on a daily agenda or working hours.
The measurements from Shelly EM are stored in a free cloud for 365 days.
Endless use applications
Monitor your home, office, or factory, and avoid additional expenses or drops in voltage that can damage your appliances and devices. Shelly 3EM can calculate 2-way consumption: produced and used energy for each of the three phases. The device can be configured to measure three separate circuits of a mono-phase electrical system and control a contactor. View the quality of your electricity network regarding active power, reactive power, voltage, and power factor.
Shelly 3EM is developed to monitor one, two, or three phases and allows you to monitor the status and history and the current and past electrical power consumption of each separate channel for the day, week, month, or year. Shelly 3EM exports all data in CSV format in 10-minute intervals, making data analysis and cutting back costs easy. That way, you can monitor the exact energy your electric car consumes and calculate what part of your electricity bill it forms.
When an electrical appliance is damaged, it doesn't simply stop working. Usually, it increases the amount of energy used in an attempt to compensate for its operational capacity. Since there is no visible difference in its performance, it might take months before you can identify a problem, leading to inefficiency and wasted energy. Shelly 3EM power monitoring will immediately read the increase in energy consumption and will notify you, saving you additional expenses on repairs or replacement of equipment.
