DIN rail smart relay Shelly WavePro3 3-channel Z-Wave, 110–240 V, 25 A per channel, AES-128, DIN mounting

Shelly Wave Pro 3 is a DIN-rail mounted 3-channel relay with Z-Wave and Z-Wave Long Range support, designed for professional and commercial electrical installations. The unit provides three potential-free relay outputs for independent control of circuits up to a combined 48 A and integrates into Z-Wave networks to enable remote control, scheduling, scenes and automation via a compatible Z-Wave gateway. The compact housing and DIN-rail form factor suit distribution boards in residential, hotel, office and industrial environments.

Advantages

The device offers three independent relay channels (16 A per channel, 48 A total), long communication range via Z-Wave Long Range (up to 1,000 m line-of-sight outdoors, up to 80 m indoors) and mesh networking capabilities for range extension. It features low idle power consumption (< 0.3 W), overheat protection that shuts the relay above 80°C with gateway notification, potential-free contacts for a wide range of load types, and OTA firmware updates. The unit supports S2, S2 Authenticated and S0 security standards for Z-Wave integration.

Suitable for

• Centralized control of lighting circuits in homes and commercial buildings
• Control of heating or other resistive loads in distribution boards
• Integration of inductive or capacitive loads (with appropriate RC/snubber) in hotel and office installations
• Large facilities where long-range Z-Wave communication is required

How to use

Install the Shelly Wave Pro 3 on a standard DIN rail inside a distribution board following local electrical codes. Connect supply and circuit wires to the potential-free terminals, observing terminal torque and wire stripping recommendations. Add the device to a compatible Z-Wave gateway using SmartStart or the Z-Wave inclusion process (scan QR code or follow gateway instructions). Configure channels, schedules and scenes in the gateway to enable remote control and automation. Ensure inductive or capacitive loads are fitted with the required RC (snubber) circuits where specified.

Recommendations

Use the Shelly Wave Pro 3 for centralized switching of lighting and medium-power equipment and avoid exceeding per-channel or total current ratings. For inductive or capacitive loads, confirm presence of RC/snubber protection. Keep the installation within the specified ambient temperature and humidity ranges and apply OTA updates through the gateway to maintain security and functionality.
