Shelly Pro 3EM energy meter CT63

What is the Shelly Pro 3EM 3CT63? The Shelly Pro 3EM‑3CT63 is a DIN-rail mounted energy meter suitable for single-phase or three-phase installations. The energy meter comes with a 63A 3-phase CT measuring coil. The meter records both accumulated energy and instantaneous voltage, current, active and apparent power per phase/channel in real-time. Real-time measurements (per phase/channel) The meter is intended to provide insight into energy flows and consumption profiles: real-time values ​​per phase/channel, plus totals. This makes the device suitable for monitoring, cost allocation, or optimization in PV applications (Photovoltaic ready). Data logging & timestamps * Local data logs: up to 60 days of storage in non-volatile memory (NVM) at 1-minute intervals. * Real-time clock: stored data retains correct timestamps, even in the event of loss of SNTP/connection. Connectivity & Protocols (Professional Integration) The Pro 3EM‑3CT63 can run standalone in a local LAN and/or Wi-Fi network. For integration with Smart Building/EMS, Shelly supports Modbus, MQTT, HTTP, and WebSocket, with all inbound connections supporting TLS. Additionally, there is an embedded Web Interface for monitoring, configuration, and operation. Relay / Contactor Control (Important to Know) This model does not have a built-in relay. Contactor control is possible with a Shelly Pro 3EM Switch Add-on connected to the Pro 3EM‑3CT63. Additional Features (according to Shelly) * Phase sequence error detection and no-load threshold. * Channel-to-channel calibration with a required load of at least 500 W per channel. * Optical pulse indication and Accuracy Class B (active energy) according to IEC 62053‑21. * KNXnet/IP support.
