• a protection control (or load up to 10 amps)
• 365 days of internal storage in case Wi-Fi is unavailable
• Voltage measurement and configurable alarm messages - Including 3x current transformer 120 amps

WHY SHELLY 3EM?

Intelligent 3-phase electricity meter and contactor control

Many appliances, homes and buildings consume more energy than they need, resulting in energy waste and higher costs. Shelly 3EM is a smart electricity meter that helps to monitor electricity consumption in real-time and notifies you if the electricity consumption of a device or installation exceeds a predetermined threshold. In addition, it enables contactor control. Smart current metering helps you identify and avoid redundant energy consumption.

Endless application possibilities

2-WAY ENERGY CONSUMPTION MONITORING

Monitor your home, office, or factory floor and avoid additional costs or voltage drops that can damage your equipment and equipment. Shelly 3EM can calculate the 2-way consumption: energy produced and consumed for each of the three phases. The device can be configured to measure three separate circuits of a single-phase electrical system and control a switching contactor. Display the quality of your power grid in terms of active power, reactive power, voltage and power factor.

SOLAR PANEL MONITORING AND CONTROL

Track how much energy your solar panels and wind turbines generate and save effortlessly. Shelly EM provides real-time information on the efficiency of the solar and wind energy system, as well as historical data on how much energy has been generated and consumed. This helps you control the flow of energy and get the most out of your solar panels and wind turbines. To take it a step further, connect a contactor to Shelly 3EM so you can automatically turn off appliances in your home that you don't absolutely need to save energy.

PREVENTIVE MANAGEMENT

When an electrical appliance is damaged, it doesn't just stop working. Usually, it increases energy consumption to compensate for its operating capacity. Since there's no visible difference in performance, it can take months to spot a problem, leading to inefficiency and wasted energy. Shelly 3EM Power Monitoring instantly detects the increase in energy consumption and notifies you, saving you additional costs on repairs or equipment replacements.
