ENERGY METER SHELLY PRO 3EM DIN, 3x120A WIFI

Shelly Pro 3EM is a three-phase energy meter that measures energy in three individual phases using current transformers, up to 120 A load with 99% accuracy. The device reports real-time accumulated energy as well as instantaneous voltage, current, and power factor per phase. It stores data in non-volatile memory accessible at one-minute intervals for up to 60 days. Shelly Pro 3EM is designed for DIN-rail mounting and comes with three current transformers. The device reports real-time measurements of power (W), voltage (V), current (A), and power factor (PF) and stores measurements locally on the device for up to 60 days and for 365 days when connected to the Shelly Cloud app. The device also meets IEC 62053-21 standard requirements with Class B accuracy (maximum 1% deviation). Shelly Pro 3EM features a built-in real-time clock that retains time and date if the connection to the SNTP server is lost. Shelly Pro 3EM can be connected to the Internet or a local 2.4 GHz Wi-Fi network. Additionally, the device has built-in Bluetooth, as with all Pro and Plus devices, enabling Shelly Pro 3EM to act as a bridge to other Shelly Bluetooth devices. The device operates locally without a connection to Shelly Cloud, but activating this connection is recommended to facilitate data storage and enhance functionality. The device can also communicate via MQTT, HTTP, and WebSocket. Furthermore, Pro 3EM supports the MODBUS bus, enabling easy and rapid integration into existing industrial installations. The device is equipped with second-generation hardware featuring a powerful ESP32 processor and enhanced safety features including over-temperature, over-current, over-voltage, and overload protection. It also enables script functionality for advanced and customized operations and supports range extension features with the device. Note! Shelly Pro 3EM does not have a built-in dry contact relay, unlike the older Shelly 3EM. Instead, a Shelly Pro Add-On module can be connected for switching up to three phases. Shelly smart home products support Amazon Alexa and Google Assistant virtual assistants. In addition to the above, several other smart home systems/platforms are supported (verify compatibility per product). Shelly products connect to a wireless Wi-Fi network and do not require a separate home automation controller to operate. Note! Installation must be performed only by a certified electrician.
