Shelly 3EM-63W Gen3 (wire model)

The Shelly 3EM-63T (Flat Terminal Model) and Shelly 3EM-63W (Wire Model) are three-phase energy meters designed to measure energy data across three individual phases with loads of up to 63A and a 99% accuracy. These devices offer real-time monitoring with one-minute resolution for parameters such as power, current, voltage, and power factor. They also store energy data in one-hour intervals for up to five years with the free app, or every minute with a Premium subscription. Key Features: High-Accuracy Monitoring: Measures power (W), voltage (V), current (A), apparent power (VA), and power factor (PF) with 99% accuracy, meeting IEC 62053-21 Class B standards. Compact Design: The electronics and current transformers are integrated into a single unit, eliminating the need for DIN rail space. These units are mounted on top or below your RCD or circuit breaker. Data Storage: Stores energy data locally for at least 7 days with 1-minute resolution and up to 5 years online via the Shelly Cloud. Built-in Real-Time Clock: Maintains accurate time and date, even without connection to an SNTP server. Advanced Connectivity: WiFi and Bluetooth: Operates on 2.4 GHz WiFi and includes built-in Bluetooth for easy setup and integration with Shelly Bluetooth devices. Local Operation: Functions 100% locally, requiring only a local network for operation, ensuring reliability even without internet access. Broad Compatibility: Integrates with over 200 systems, including Google Home, Amazon Alexa, Home Assistant, Samsung SmartThings, Athom Homey, and KNX. The Shelly 3EM models are designed for simple and flexible installation directly atop or below your circuit breaker or RCD. This minimizes space requirements and ensures a tidy setup. Advanced Hardware and Security: Future-Proof Technology: Powered by the ESP-Shelly-C38F CPU with 8MB flash memory, enabling advanced scripting and virtual device functionality. Secure Communication: Supports MQTT, HTTP, and WebSocket protocols with TLS encryption for enhanced security. These three-phase energy meters are ideal for electricians, property managers, and smart home enthusiasts looking for a reliable, compact, and accurate solution for energy monitoring. Whether for residential, commercial, or industrial applications, the Shelly 3EM models deliver robust features and seamless integration into modern smart home and building automation systems.
