Product Details

The Shelly Pro 3EM-3CT63 is a DIN-rail three-phase energy meter that clamps onto your incoming lines with slim 63A current transformers. It reports voltage, current and power per phase in real time, with 1% accuracy, so you can see exactly how a home or small business uses electricity.

It connects over Wi-Fi, Bluetooth and wired LAN, stores 60 days of history on the device, and supports MQTT and Modbus for energy dashboards and integrations. It can also measure produced energy, which makes it a good fit for solar setups, and it can monitor three separate single-phase circuits instead.

For installers and energy-conscious owners who want detailed, accurate monitoring, the Pro 3EM-3CT63 turns the panel into a live energy dashboard.
