## Long description

The Shelly Pro 3 Black 48 A 110-240 V is a compact, DIN-rail mountable 3-channel smart relay designed for reliable control of electrical circuits. It supports Wi‑Fi 802.11b/g/n and provides potential-free contacts to switch three independent loads, including three-phase installations. With a maximum switching capacity of 48 A and an AC input voltage range of 110–240 V, the device combines a small footprint (59 × 53 × 96 mm) with flexible connectivity options including local Wi‑Fi operation, LAN integration and optional cloud access. An embedded web interface allows direct monitoring, configuration and control from any modern browser.
Advantages
The Shelly Pro 3 offers three fully independent channels that can be configured separately for different loads and control scenarios, enabling multi-circuit management in a single module. Its potential-free outputs make it suitable for various wiring schemes and allow safe integration with external contactors or control systems. Built-in LAN and Wi‑Fi connectivity, along with gen2 firmware features, deliver flexible local and remote control, while the embedded web interface provides straightforward setup and diagnostics without additional software. The compact DIN-rail design simplifies installation in electrical cabinets and reduces space requirements.
