## Long description

Shelly Pro 3EM-3CT63 is a DIN-rail mountable single- or three-phase energy meter designed for monitoring AC electrical consumption up to 63 A. The compact unit (94 × 19 × 69 mm) works with three external current transformers and reports accumulated energy, instantaneous voltage, current, active and apparent power per phase in real time. It supports LAN and Wi‑Fi connectivity, Modbus, MQTT, HTTP and WebSocket protocols with TLS for inbound connections, and stores up to 60 days of 1‑minute interval measurements in non-volatile memory. The device includes a real-time clock and an embedded web interface for local configuration, monitoring, and remote access within the same network.
Advantages
The meter combines DIN-rail form factor and compact dimensions for easy installation in distribution panels. It offers flexible connectivity (LAN/Wi‑Fi) and multiple communication protocols (Modbus, MQTT, HTTP, WebSocket) for integration with automation systems. Data logging to non-volatile memory for up to 60 days at 1‑minute resolution and a real-time clock ensure reliable historical records. TLS support for inbound connections increases communication security. The device can operate standalone in a local network or be integrated into cloud and third‑party systems.
Suitable for
Monitoring energy consumption in residential distribution boards
Tracking multi-circuit or three-phase consumption in small commercial installations
Integration with building automation systems via Modbus, MQTT or HTTP
Energy cost calculation and consumption reporting for tenants or operators
