Shelly smart three-phase energy meter 120 A with Wi‑Fi/LAN and Bluetooth for DIN rail
Shelly smart three-phase energy meter 120 A with Wi‑Fi/LAN and Bluetooth for DIN rail
Accurate three-phase measurement up to 120 A
Monitor voltage, current, and active and apparent power for each phase with accuracy up to 1%. One‑minute logs over the last 60 days allow detailed analysis and optimization of consumption.
Wi‑Fi/LAN and Bluetooth for easy connectivity
The device operates on local LAN and over Wi‑Fi, supports Bluetooth for quick pairing, and is ready for smart‑home integration without relying on the cloud.
DIN‑rail mounting and robust design
A compact form factor for panels with DIN‑rail mounting, a plastic enclosure, and an integrated temperature sensor ensure safe and stable operation across a wide range of conditions.
Shelly Pro 3EM 120 A is a reliable three‑phase energy meter for detailed consumption monitoring. It measures voltage, current, and active/apparent power in real time on each phase, calculates power factor, and stores one‑minute data for up to 60 days for accurate analysis. With LAN, Wi‑Fi, and Bluetooth support, you can easily connect it to your network without requiring the cloud.
The device supports MQTT, HTTP, and WebSocket for automation integration and offers advanced scripting. Thanks to DIN‑rail mounting and low self‑consumption, it is ideal for distribution boards in homes, businesses, and photovoltaic systems.
