Next generation of DIN rail-mounted energy meters for single or three-phase applications with a combined 63A, 3-phase current transformer.

The Shelly Pro 3EM-3CT63 is a DIN rail-mounted energy meter for single or three-phase applications. It is equipped with the full flexibility of Gen2 firmware and LAN connectivity, providing professional integrators with additional options for end-user solutions. It can operate independently in a local LAN and/or Wi-Fi network or through cloud home automation services using Modbus, MQTT, HTTP, and WebSocket. All incoming connections support TLS.

The device reports accumulated energy as well as instantaneous voltage, current, active power, and apparent power per phase/channel in real-time. It stores data in non-volatile memory, which can be retrieved over a period of up to 60 days in 1-minute intervals.

The device features a real-time clock that maintains the correct time in case the connection to an SNTP server is lost.

The Shelly Pro 3EM-3CT63 can be accessed, configured, and monitored remotely by the user, and the device can access and communicate with an automation system as long as they are on the same network.

The device has a built-in web interface that can be used to monitor and control the device as well as to adjust its settings.

Note: The device does not have a built-in relay. The control of the contactor is done through a Shelly Pro 3EM Switch add-on connected to the Shelly Pro 3EM-3CT63.
