Energy meter DIN 3EM-63W

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

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

Both models are easily installed and controlled via the Shelly Smart Control app or your preferred smart home or smart building system. Shelly devices operate completely locally and only require a local network. They are compatible with over 200 partner systems, including Google Home, Amazon Alexa, Home Assistant, Samsung SmartThings, Athom Homey, KNX and many more. The devices are designed to be combined with the current transformer in a single unit. This means that they do not take up space on the DIN rail, but can be mounted on the top or bottom of your RCD or group circuit breaker.

Measurement functions
- Real-time reporting: Measures and reports power (W), voltage (V), current (A), apparent power (VA) and power factor (PF).
- Data storage: Saves measurements locally for at least 7 days (1-minute interval) and up to 5 years online via Shelly Cloud.
- Accuracy: Meets IEC 62053-21 requirements with Class B accuracy (maximum 1% deviation).
- Built-in real-time clock: Ensures correct time and date even in the event of a network outage.

The Shelly 3EM-63T and 3EM-63W connect via 2.4 GHz WiFi and also have built-in Bluetooth. This makes them compatible with Shelly's Pro, Plus and Gen3 devices and enables use as a gateway for Shelly's battery-powered Bluetooth devices. The Shelly 3EM-63T and 3EM-63W are reliable, efficient and flexible solutions for energy measurement and control in three-phase systems.
