Shelly Pro 3EM-3CT 63

Next generation of DIN rail mountable 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 mountable energy meter for single or three phase applications. It is equipped with all the flexibility of Gen2 firmware and LAN connectivity and offers professional integrators additional options for end customer solutions. It can operate standalone on a local LAN and/or Wi-Fi network or via cloud home automation services using Modbus, MQTT, HTTP and WebSocket. All incoming connections support TLS.

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

The device has a real-time clock that maintains the correct time if the connection to an SNTP server is lost.

The Shelly Pro 3EM-3CT63 can be accessed, set up 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 an integrated web interface that can be used to monitor and control the device and customise its settings.

Note: The device does not have a built-in relay. The contactor is controlled via a Shelly Pro 3EM switch add-on connected to the Shelly Pro 3EM-3CT63.
