Shelly Pro 3EM-3CT63 Single or Three-Phase DIN-Rail Energy Meter

The Shelly Pro 3EM-3CT63 is designed to be mounted on the DIN rail of the breaker box directly over the circuit breaker, and features options for connectivity over either LAN for optimum reliability and security, or WiFi or Bluetooth as a backup where required. The 3EM-3CT63's included 3-phase current transformer is capable of measuring up to 63A to within 1% accuracy, making it suitable for measuring and monitoring a wide variety of capacitive and inductive loads such as electronic vehicle charging and commercial building energy management.

In addition to measuring energy expenditure of the system in which it's installed, Shelly's Pro 3EM-3CT63 is also capable of measuring energy production from renewable energy sources such as wind turbines or solar panels, and, when combined with other Shelly devices in a smart scene, can direct surplus energy to appliances or installed batteries. Similarly, the Pro 3EM-3CT63 can instruct other Shelly devices to deactivate non-essential appliances and systems once a pre-determined energy usage threshold is reached, reducing energy bills and your carbon footprint.
