• one contactor control (or load up to 10A)
• 365 days of internal memory in case Wi-Fi is not available
• voltage measurement and configurable alarm reporting
• Included 3x Current Transformers 120A

Wireless
Shelly 3EM can be connected to any Wi-Fi network or can operate as an Access Point.

Control remotely
Control Shelly 3EM directly from your smartphone or tablet and manage its output from the Shelly Cloud app, MQTT, or Rest API.

Highly compatible
Shelly 3EM is compatible with both Android and iOS.

Overconsumption and over energy protection
Shelly 3EM will automatically turn off the whole circuit if consumption or energy reaches the set limit.

Sunrise/Sunset schedules
Automatically follow the sun and turn Shelly 3EM ON/OFF based on the sunrise and sunset hours.

Weekly schedules
Choose a time and create custom daily schedules for your Shelly 3EM.

Monophase systems
Shelly 3ЕМ can also monitor monophase electrical systems with up to 3 points simultaneously.

WHY SHELLY 3EM
The professional 3-phase energy meter.
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 points of a mono-phase electrical system and measure each of them separately.

CONNECT IN A MINUTE & CONTROL IT ALL
Shelly 3EM has integrated relay output which can be used for contactor control. Real-time and historical information about the efficiency of the solar or wind energy system and how much energy has been produced. Control your monthly expenses by saving on money and energy!

365 DAY BUILT-IN ENERGY HISTORY
We developed Shelly 3EM to allow you to monitor the status and history, as well as the current and past electrical power consumption for the day, week, month, or year. Shelly 3EM exports all data in CSV format in 5-minute intervals. The information can help for analysis and detailed statistics. All data gets stored in the cloud at incrementing intervals.

THE PERFECT SOLUTION FOR MANUFACTURERS
Shelly 3EM can do all the work for you. The 3-phase energy meter can calculate energy cost for production, notify you if a machine is powered on during non-working hours, measure the real working time of each machine and allows remote On/Off control for power optimization.

FULL PROTECTION
Shelly 3EM will automatically shutdown and notify you when the defined consumption limit is exceeded.

ОPTIMIZE ENERGY USAGE
Ever wanted to live sustainаbly and save energy, money, and CO2? With Shelly 3EM, you can monitor the consumption оf each circuit, appliance, or of your whole home to optimize energy usage. In case you have solar panels or wind turbines, you can be aware how much energy was produced and make savings effortless.

DETAILED INFO ABOUT ELECTRICITY CONSUMPTION
Having more detailed information about electricity consumption at your manufacturing facility is crucial for the optimization of overall production costs and idle power. View the quality of your electricity network regarding active power, reactive power, voltage, and power factor. Monitor your facility or home to avoid additional expenses or drastic drops in voltage that may damage your appliances and machines.

ONE APPLICATION COUNTLESS POSSIBILITIES
With the best cloud service in the world, user-friendly interface, scenes, bulk control, and much more, the Shelly Cloud application allows you to control your home from anywhere. Each Shelly can be integrated and works with all other Shelly devices in the Shelly app.

ENERGY EFFICIENCY
Many homes and buildings use more energy than they need. That leads to inefficiencies, energy waste, and eventually increased monthly bills.
Shelly home and facility automation solutions can help you reduce the energy waste and your monthly bills by up to 30% through a 3-step cycle of energy efficiency.

FOR DEVELOPERS
