Shelly Pro 3EM Three-phase WiFi Energy Meter

The Shelly Pro 3EM is a 3-phase energy meter that measures up to 120A per phase with an accuracy of 1% via the included current clamps. It is also capable of measuring three individual phases. With the Shelly Pro 3EM, you can monitor the total consumption of your apartment or house and locate energy hogs by measuring energy, optimizing electricity consumption to save energy. If activated, the measured data is stored in the cloud and you can graphically represent the consumption on the APP. The Shelly is designed for DIN rail mounting in the fuse box/electric cabinet. Thanks to the Bluetooth connection, Shelly Pro devices can be easily configured with the Shelly app and integrated into the WLAN. If you do not have WLAN available, you can connect the Shelly directly to your switch via a LAN network cable. Historical data is stored for up to 60 days, with each phase having a one-minute resolution.

Attention:
Working on the 230V/400V network is dangerous and can lead to fatal accidents. Therefore, always disconnect the device from the network and switch off the fuses when connecting or when the casing is open. We assume no liability for improper use of the device. If you do not trust yourself to install the device, it is better to have it installed by an electrician.
