- Class B accuracy for active energy (compliance with IEC 62053-21 based on manufacturer tests)
- Suitable for photovoltaics
- Detection of errors in the phase sequence (option)
- Optical pulse display of energy consumption
- measurement accuracy of 1%
- Memory that can be accessed in 1-minute intervals over a period of up to 60 days
- Package contains 3 x 400 A current transformers
The Shelly Pro 3EM 400A is a WiFi-powered, DIN-mountable 3-phase energy meter with WiFi, Bluetooth and LAN connectivity. With its 1% active energy metering accuracy, the Shelly Pro 3EM can be used to monitor the consumption of all household appliances, circuits and office equipment individually. Historical data is stored for up to 60 days, with each phase having a one-minute resolution. In addition, the scripting functionalities allow the execution of complex scenarios and offer advanced monitoring capabilities.
Shelly Pro 3EM-400 supports mTLS for MQTT, HTTP and secure outbound WebSockets. Commercial-grade security enables direct connections to your cloud infrastructure and reduces the cost of deploying complex networks and VPNs.
Shelly Pro 3EM 400A offers MODBUS support for voltage, current, power and energies. Your energy consumption and instantaneous values of voltage, current and power are accurately recorded. Our new firmware platform enables a custom implementation that can report to your infrastructure every 100 ms.
Monitor your home, office or factory to avoid unnecessary expenses or voltage drops that can damage your household and office equipment. Shelly Pro 3EM can calculate two-way consumption: energy produced and consumed for each of the three phases. The device can also be configured to measure three separate circuits of a single-phase electrical system. Display the quality of your power grid in terms of active power, reactive power, voltage and power factor.
Thanks to the Shelly Pro 3EM 400A's scripting functionalities and webhooks, you can easily control other Shelly or WiFi devices on your local network. Use these features to set precise parameters for heating, cooling or charging electric vehicles based on your PV generation and to automatically disconnect your devices from power consumption. All of this works without having to use a cloud.
