Product information

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.

Suitable for

  • Controlling lighting circuits, including multi-zone and three-phase lighting
  • Switching motors, pumps and HVAC equipment within the rated current
  • Integration into home or building automation systems via local network or cloud
  • Professional electrical cabinets and distribution boards where DIN-rail mounting is required

Key specifications

  • Channels: 3 independent relay channels with potential-free contacts
  • Maximum switching current: 48 A
  • Operating voltage: AC 110–240 V
  • Wireless: Wi‑Fi 802.11b/g/n
  • Mounting: DIN-rail compatible enclosure
  • Dimensions: 59 × 53 × 96 mm
  • Interface: Embedded web interface; supports local LAN and optional cloud access

How to use

Mount the Shelly Pro 3 on a standard DIN rail inside an electrical cabinet and wire the input and output circuits following local electrical codes and safety practices; use the potential-free contacts to connect external loads or contactors as required. Connect the device to a Wi‑Fi network (802.11b/g/n) or to the local LAN to enable remote access and configuration. Use the embedded web interface to assign channel behavior, set switching schedules, monitor current and status, and adjust networking options. For three-phase or heavy-load applications, verify proper load distribution and cooling within the enclosure.

Usage recommendations

Ensure installation by a qualified electrician and confirm that connected loads do not exceed the 48 A rating. Use appropriate protective devices such as breakers or fuses on each circuit. For reliable remote operation, maintain a stable network connection and secure the device with strong network credentials and up-to-date firmware.
