Shelly Pro 3EM-3CT63

With the Shelly PRO 3EM 3CT63 WiFi Energy Meter, you can wirelessly or via Ethernet cable easily and accurately monitor and record energy consumption for 3-phase or 3x single-phase systems, such as your solar panels. What's new with the Shelly PRO 3EM 3CT63 is the small and easy to install CT-clamp. Like with the Pro 3EM, it includes a fast ESP32 chip, support for both WiFi and LAN connections, and of course, a DIN-Rail version. Its open-source nature ensures that your Shelly 3EM can integrate with nearly any home automation system. Shelly also offers its own free app that lets you easily and affordably set up a Smart Home System without the cost of a Gateway/Hub. 

The Shelly PRO 3EM 3CT63

Can monitor 3-phase or up to 3 groups single phase;
3x Power (W) measurement
3x Energy (Wh) measurement
3x Load (max. 63A) measurement
3x Load Quality measurement
1x Voltage (V) measurement
Additionally;
60 days of built-in energy (Wh) history per minute

Install the Shelly PRO 3EM according to the instructions, connect to your home WiFi (optionally via Bluetooth) or LAN using the free Shelly App, and pair the Module. It couldn't be simpler! The Shelly PRO 3EM Energy Meter operates at 110-240VAC and has a built-in ESP32 with a 16MB flash chip. This allows you to flash your own or alternative firmware.
Note, the CT clamp cannot be opened so its mandatory to install over the phase wires by detaching them. The CT-clamp size is much smaller with 14x54x26 mm. If you do not want or have the expertise to detach the phase wires, choose the Shelly Pro 3EM with 3x120A clamps, which can be opened, but are quite large at approximately 30x30x45mm each.

With the Shelly Pro 3EM, you can create scenes to control other Shelly devices based on power consumption or power return. Ideal for this purpose is the new Shelly Pro 3EM Switch Add-On, which also features DIN-Rail mounting and clicks onto the Pro 3EM. Afterward, you can directly control the potential-free relay up to 2A with a maximum of 240VAC or 30VDC from the Shelly Pro 3EM.

Prefer not to use the free Shelly cloud service but still want to control your devices remotely? No problem. The Shelly PRO 3EM also supports basic MQTT (Message Queue Telemetry Transport) for reliable connections via a central mediator: the MQTT broker. The involved devices communicate only with the broker and do not need to know each other's IP addresses or technical details. Thus, it's safe and reliable, with real-time monitoring and easy integration. Want to know more? Check out our Shelly WiFi Switch Blog.
