    Description

    Shelly Pro 3 DIN Rail 3-Channel Wi-Fi Smart Relay Switch 48A Total

    The Shelly Pro 3 is a professional-grade 3-channel DIN rail smart relay switch designed for advanced home and commercial automation. With potential-free dry contacts, it can control three completely independent circuits, including 3-phase systems, with 16A per channel and up to 48A total capacity. Featuring Wi-Fi, LAN Ethernet, and Bluetooth connectivity, the Shelly Pro 3 delivers reliable, hub-free automation with remote control via the Shelly Smart Control app, voice assistants, or integration with platforms like Home Assistant, Amazon Alexa, and Google Home.

    Key Features

    • Triple-Channel Control: Independently switch three separate circuits or control 3-phase electrical systems with 16A per channel
    • Dual Connectivity: Simultaneous Wi-Fi and LAN Ethernet connection for maximum reliability and failover backup
    • Potential-Free Dry Contacts: Wide voltage support from low voltage DC to 240V AC for flexible applications
    • Advanced Safety: Built-in overvoltage, overpower, and temperature protection with automatic shutoff and notifications
    • No Hub Required: Works standalone on your local network or integrates with cloud automation services
    • Custom Scripting: Supports mJS scripting for advanced automation scenes based on external data or triggers

    Professional DIN Rail Installation

    Designed for installation inside electrical cabinets and breaker boxes, the Shelly Pro 3 mounts easily on standard DIN rails. Its compact design and flame-resistant materials make it ideal for residential, commercial, office, and industrial environments. Perfect for controlling lighting circuits, HVAC systems, boilers, contactors, pumps, and other high-load appliances with professional reliability.

    Smart Home Integration & Control

    Control your circuits from anywhere using the Shelly Smart Control app on iOS or Android. Set schedules, create automation scenes, and monitor device status in real-time. The Shelly Pro 3 integrates seamlessly with Amazon Alexa, Google Home, Home Assistant, Samsung SmartThings, and supports MQTT, HTTP REST API, and WebSocket protocols for custom integrations. TLS 1.2 security ensures encrypted communication for local and cloud connections.

    Enhanced Safety & Monitoring

    The Shelly Pro 3 includes temperature monitoring every 100ms, automatically shutting off outputs if unsafe heat levels are detected. Overvoltage and overpower protection safeguards connected appliances from electrical damage, immediately switching off and sending notifications when thresholds are exceeded. All Shelly Pro components are manufactured with flame-resistant materials for added safety.
