Energy meter DIN Pro 3EMArt. no.: 0900471
The Shelly Pro 3EM CT63 is a three-phase energy meter that uses current transformers to measure energy data across three individual phases, supporting loads of up to 63A with 99% accuracy. The device measures power, current, voltage, and power factor, providing real-time data with a one-minute resolution. Energy data is stored in one-hour intervals for up to 5 years via the free app, or in one-minute intervals with a Premium subscription.
The Shelly Pro 3EM CT63 is easily set up and controlled through the Shelly Smart Control app or your preferred smart home or smart building system. Shelly devices operate 100% locally, requiring only a local network to function. Shelly can be used standalone within the Shelly Smart Control app or integrated with over 200 partner systems, such as Google Home, Amazon Alexa, Home Assistant, Samsung SmartThings, Athom Homey, KNX, and many others.
Designed for DIN-rail mounting, the Shelly Pro 3EM CT63 comes with a single current transformer block featuring an aperture for each phase conductor. This current transformer unit is highly compact compared to traditional individual current transformers, making it a perfect fit for three-phase electrical installations.
The device reports power (W), voltage (V), current (A), apparent power (VA), and power factor (PF) in real time. It stores these measurements locally for up to 365 days, and for up to 5 years online when Shelly Cloud is enabled. Furthermore, the device complies with the IEC 62053-21 standard, meeting Class B accuracy requirements (with a maximum deviation of 1%). Additionally, the Shelly Pro 3EM features... built-in real-time clock, allowing it to maintain the time and date even if the connection to an SNTP server is lost.
The Shelly Pro 3EM can connect to the internet or a local network via a LAN interface and/or 2.4 GHz WiFi. Furthermore, the device features built-in Bluetooth—much like the rest of the Pro, Plus, and Gen3 series—enabling it to simultaneously function as a gateway for Shelly Bluetooth devices.
