Shelly Pro 3EM CT63

Shelly Pro3 EM CT63 is a three-phase energy meter that uses current transformers to measure energy data on three individual phases with loads up to 63A and with 99% accuracy. The device measures power, current, voltage, and power factor with a resolution of one minute in real-time. All energy data is stored at hourly intervals for up to 5 years with the free app and every minute with a Premium subscription. 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 work 100% locally and only require a local network to operate. 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. Function: Shelly Pro 3EM CT63 is designed for DIN rail mounting and comes with a single current transformer with a hole for each phase wire. The current transformer is very compact compared to traditional individual current transformers and fits perfectly on a three-phase group. The device reports power measurement (W), voltage measurement (V), current measurement (A), apparent power (VA), and power factor (PF) in real-time and stores the measurements for up to 365 days on the device and up to 5 years online with Shelly Cloud activated. The device also meets the requirements of IEC 62053-21 with an accuracy equivalent to Class B (maximum 1% deviation). Shelly Pro 3EM also has a built-in real-time clock, so it can maintain time and date in case of lost connection to an SNTP server. Connection: Shelly Pro 3EM can connect to the internet or the local network through a LAN interface and/or 2.4 GHz WiFi. Additionally, the device has built-in Bluetooth like the rest of the Pro, Plus, and Gen3 devices, so it can also be used as a gateway for Shelly Bluetooth devices. Shelly Pro 3EM works locally without connection to Shelly Cloud, but it is recommended to activate it for easy data storage and increased functionality. The device can also communicate via MQTT, HTTP, and WebSocket. All support TLS. Shelly Pro 3EM also supports Modbus TCP connection. Hardware: The device is equipped with a powerful ESP32 processor. This allows for scripting functions for advanced and customized functionality as well as a range extender function with the device. Note: Shelly Pro 3EM does not have a built-in relay output. If local relay control independent of the network is desired, the Pro 3EM Switch Add-on (3800235268131) can be purchased, which allows for external relay control.
