![](/p.gif) | Shelly Pro 3EM-400 is a DIN rail mountable three-phase energy meter. Enhanced with all the gen2 firmware flexibility and LAN connectivity, it provides professional integrators with additional options for end-customer solutions. Shelly Pro 3EM-400 reports accumulated energy as well as instantaneous voltage, current, and power factor per phase in real-time.
Next-generation 3-Phase Energy Meter Shelly Pro 3EM-400 is a Wi-Fi-operated DIN-mountable 3-Phase Energy Meter with Wi-Fi, Bluetooth, and LAN connectivity. With active energy measurement accuracy of 1%, Shelly Pro 3EM-400 can be used to monitor the consumption of home appliances, business electric circuits, and office equipment individually. It features 60 days of on-device historical data with a 1-minute resolution for each phase. Additionally, its scripting functionalities allow for the execution of complex scenes and provide broader monitoring abilities.
