The Shelly PRO 3EM is a professional-grade, DIN rail mountable energy meter designed for three-phase electrical systems. Featuring the advanced capabilities of Shelly's Gen2 firmware, this meter offers unparalleled flexibility and seamless connectivity.
Equipped with LAN and Wi-Fi networking, the Shelly PRO 3EM can operate as a standalone unit within a local network, providing real-time insights into your electrical system. It reports accumulated energy usage as well as instantaneous voltage, current, active power, and apparent power measurements per phase.
Data is stored in the meter's non-volatile memory, allowing you to review usage history for up to 60 days in 1-minute intervals. This detailed energy data gives you the insights needed to optimize your power consumption and identify potential inefficiencies.
Real-time Clock to keep the correct time if the connection to an SNTP server is lost.
Included with the Shelly PRO 3EM are three 120A current clamps, providing a complete metering solution right out of the box. The DIN rail mounting design ensures a streamlined and professional installation in electrical panel environments.
Whether you're a facility manager, energy auditor, or simply looking to closely monitor your energy usage, the Shelly PRO 3EM is an advanced, connected three-phase energy meter built to deliver the performance and flexibility you need.
*The Device does not have a built-in relay. Contactor control is provided using a Shelly Pro Addon attached to the Shelly Pro 3EM.
