About the Wireless Switch Shelly Pro 3EM 400A White

Shelly Pro 3EM 400A

Shelly Pro 3EM-400 is a three-phase power meter for DIN rail assembly. It has been enhanced with all the flexibility of gen2 firmware and LAN connectivity, providing professional integrators with additional options for end-user solutions. Shelly Pro 3EM-400 displays the accumulated energy as well as instant voltage, current and power factor per stage in real time.

Last generation three-phase current consumption meter

O Shelly Pro 3EM 400A is a WLAN-powered three-phase current consumption meter and DIN-mountable with WLAN, Bluetooth and LAN connectivity. With its 1% active energy measurement accuracy, the Shelly Pro 3EM can be used to individually monitor the consumption of all household appliances, power circuits and office equipment. Historical data is stored for up to 60 days, with each phase having one minute resolution. In addition, scripting features allow running complex scenarios and provide advanced monitoring features.

4 quadrants measurement

To measure the capacitive and inductive load types of imported and exported active energy.

Accuracy class B (active energy)

O Shelly Pro 3EM-400 has a measurement accuracy of 1%.

Support MODBUS

It allows easy and fast deployment in existing industrial plants.

Connectivity WLAN, LAN and Bluetooth

Simultaneous use of Ethernet and WLAN. Support MQTT, input and output WebSocket, UDP, mTLS.

Electrical network monitoring

Monitors single-phase electrical systems with up to 3 points simultaneously. Fast and minimum notifications of 60 days of 1 minute record retention.

Script capabilities

Shelly Pro 3EM-400 provides full support for mjS scripts, allowing you to create additional features and features.

Commercial level safety

Shelly Pro 3EM-400 supports mTLS for MQTT, HTTP and secure output WebSockets. Commercial-level security allows direct connections to your cloud infrastructure and reduces the cost of deploying complex networks and VPNs.

Industrial facilities

Shelly Pro 3EM 400A provides support for MODBUS for voltage, current, power and energies. Their power consumption and instant voltage, current and power values can be accurately captured. Our new firmware platform allows a personalized implementation that can report to your infrastructure every 100 ms.

Two-way power consumption monitoring

Monitor your home, office or factory to avoid unnecessary expenses or voltage drops that can damage your home and office equipment. Shelly Pro 3EM can calculate bidirectional consumption: energy produced and consumed for each of the three phases. The device can also be configured to measure three separate circuits from a single-phase electric system. Display the quality of your power system in terms of active power, reactive power, voltage and power factor.
