Shelly Pro 3EM 3CT 63 Energy Meter

Shelly Pro 3EM 3CT 63 Energy Meter

The Shelly Pro 3EM 3CT63 is an advanced 3-phase energy meter designed for accurate monitoring of energy consumption in both residential and commercial installations. Using the included 3CT63 current transformers, you can easily measure energy consumption per phase and gain insight into voltage, current, active power, and reactive power. Thanks to its high measurement accuracy of ±1%, this energy meter is ideal for analyzing consumption, optimizing energy use, and better managing high-consumption devices.

Accurate energy measurement per phase

The Shelly Pro 3EM 3CT63 provides a complete overview of your electrical system by monitoring each phase individually. You’ll receive information on current power consumption, power, and voltage, allowing you to see exactly where energy is being used.

Measurement data can be stored locally for up to 60 days at one-minute intervals. This makes it easy to view historical data, analyze consumption patterns, and identify opportunities to save energy.

Connectivity and Smart Home Integration

Thanks to support for Wi-Fi, Bluetooth, and LAN (Ethernet), the Shelly Pro 3EM 3CT63 integrates easily into virtually any smart home system. The LAN connection ensures a stable connection in the utility closet, while Wi-Fi and Bluetooth offer additional flexibility during installation and use.

The energy meter operates entirely locally via its built-in web interface and can be integrated with popular platforms such as Home Assistant. In addition, the module supports protocols such as MQTT, Modbus, and Webhooks, enabling extensive automation.

Suitable for smart energy automation

With the Shelly Pro 3EM 3CT63, you can create smart scenarios based on your energy consumption. For example, you can set up alerts for high energy consumption, optimize device usage based on available energy, or combine it with other smart modules for automatic control.

The energy meter itself does not have a built-in relay. If you want to automatically turn devices on or off based on the measurement data, you can expand the module with an optional switch add-on.

Professional installation in the utility closet

The Shelly Pro 3EM 3CT63 is designed for DIN-rail mounting and therefore fits neatly into the meter cabinet. The included CT63 current transformers are placed around the phase wires to safely and accurately measure energy consumption.

After installation, you can configure the meter via the local web interface or integrate it directly into your existing smart home system. This way, you’ll always have access to current and historical energy data, without relying on a cloud connection.
