Shelly 3EM-63T Gen3 (flat terminal model) - WiFi 3-phase energy meter 63A

Shelly 3EM-63T (flat terminal model) and 3EM-63W (wire model) are three-phase energy meters for measuring energy data on three individual phases with loads up to 63A and with 99% accuracy. The devices measure power, current, voltage and power factor in a resolution of one minute with real-time measurement. All energy data is stored at hourly intervals for up to 5 years with the free app and every minute with the Premium subscription.

The device is available in two variants:

• Shelly 3EM-63T Gen3 (flat terminal model): 3800235261941
• Shelly 3EM-63W Gen3 (wire model): 3800235261958

Shelly 3EM-63T and 3EM-63W are easily set up and controlled through the Shelly Smart Control app or your preferred Smart Home or Smart Building system. Shelly devices work 100% locally and only need a local network to work. Shelly can be used alone in the Shelly Smart Control app or with more than 200 partner systems such as Google Home, Amazon Alexa, Home Assistant, Samsung SmartThings, Athom Homey, KNX and many more.

Shelly 3EM-63T and 3EM-63W are designed as a single unit, where the electronics and the current transformer are combined. This means that you do not need to take up DIN rail space with these devices, which instead sit on the top or bottom of your RCD or group switch.

The devices report power measurement (W), voltage measurement (V), current measurement (A), apparent power (VA) and power factor (PF) in real time and store the measurements for a minimum of 7 days on the device in 1-minute intervals and for up to 5 years online with Shelly Cloud enabled. They also meet the requirements of IEC 62053-21 with an accuracy equivalent to Class B (maximum 1% deviation). The devices have a built-in real-time clock, so they can maintain time and date in the event of a lost connection to an SNTP server.

Shelly 3EM-63T and 3EM-63W can be connected to the Internet or local network via a 2.4 GHz WiFi. In addition, they have built-in Bluetooth like the rest of the Pro, Plus and Gen3 devices, which is why they can also be used as a gateway for Shelly Bluetooth battery-powered Bluetooth devices.

Advanced features
The devices are equipped with generation 3 hardware, which includes the powerful ESP-Shelly-C38F CPU with 8MB flash. This makes them future-proof and allows the use of scripting functions and virtual devices for advanced functionality. The devices can also communicate via. MQTT, HTTP and WebSocket. All support TLS.
