Shelly Pro 3
The Shelly Pro 3 is a professional-grade 3-channel DIN rail relay designed for demanding residential and commercial automation applications. With potential-free outputs supporting a combined maximum of 48A across its three independent channels, each rated at 16A, this device delivers the power handling capability needed for controlling substantial electrical loads.
Connectivity options include LAN, Wi-Fi, and Bluetooth, providing multiple pathways for integration into your building automation system. The dry contact design allows for flexible load connections including different voltage systems and phases, with support for controlling three separate phases simultaneously. This makes the Shelly Pro 3 ideal for complex installations requiring independent control of multiple circuits.
Built-in overpower and overvoltage protection safeguards both the device and connected equipment from electrical faults. The Shelly Pro 3 supports KNXnet/IP communication for integration with professional building management systems, while remaining accessible for DIY installations through the Shelly app and compatibility with Amazon Alexa, Google Home, and other voice assistants.
