## Summary description

The Shelly Pro 3EM-3CT63 is an AC energy cost meter with a maximum current of 63 A and a frequency range of 50-60 Hz. Its compact dimensions of 94 mm width, 19 mm depth, and 69 mm height make it suitable for various installations. This device allows for accurate monitoring of energy consumption, helping to optimize energy costs and improve efficiency.

## Long description

The Shelly Pro 3EM-3CT63 AC energy cost meter is a DIN-rail mountable single- or three-phase metering device designed for professional and residential electrical installations. With support for up to 63 A per combined input and a frequency range of 50–60 Hz, it provides real-time measurement of voltage, current, active and apparent power per phase. The compact dimensions (94 mm × 19 mm × 69 mm) and LAN/Wi‑Fi connectivity allow flexible mounting in distribution boards and integration into local networks or cloud-based automation platforms.
Advantages
The device delivers continuous monitoring of accumulated energy and instantaneous electrical parameters with 1-minute interval storage for up to 60 days in non-volatile memory. It supports secure communications via Modbus, MQTT, HTTP and WebSocket, with TLS protection for inbound connections. An embedded web interface and remote access options simplify setup, monitoring and integration with third-party automation systems. A built-in real-time clock maintains accurate timestamps if SNTP servers are unavailable.
Suitable for
 Monitoring single-phase or three-phase energy consumption in homes and small businesses
 Integration with building automation and energy management systems via Modbus, MQTT or HTTP
 DIN-rail installations inside distribution boards and electrical panels
 Recording and analysing short-term energy trends with 1-minute resolution

How to use
Install the Shelly Pro 3EM-3CT63 on a standard DIN rail inside the distribution board, connect the current transformers and supply wiring according to the wiring diagram provided by the manufacturer, and ensure the device is connected to the local LAN or Wi‑Fi network. Access the embedded web interface from a browser on the same network to configure metering parameters, network settings and data reporting. For integration with automation platforms, enable the preferred protocol (Modbus, MQTT, HTTP or WebSocket) and provide the required credentials and endpoints. Note that the device does not include a built-in relay; contactor control requires the compatible Shelly Pro 3EM Switch add-on.
Usage recommendations
Ensure installation and wiring are performed by a qualified electrician. Place current transformers correctly around conductors and verify phase assignment during commissioning. Regularly back up configuration and exported data if long-term records are required beyond the device’s internal 60-day storage.
