## Long description

Shelly SHELLY\_PBS\_SW40 is a smart relay for switching high-power AC loads in residential and commercial electrical installations. Rated for up to 25 A and 6000 W with an AC input range of 110–240 V, the device offers integrated power metering and secure communication via HTTPS and TLS. The compact white housing includes mounting brackets and large terminals to simplify installation and connection to existing circuits. It supports Wi‑Fi and Bluetooth connectivity and provides the full set of Shelly features such as scripting, webhooks, MQTT and other open protocols.
Advantages
The relay combines high current capability with built‑in energy measurement, allowing precise control and monitoring of large appliances without the need for an external hub. Overvoltage and overpower protection help protect connected equipment, while support for secure protocols and custom certificates enables safer remote control and automation. Compatibility with common automation methods and documented interfaces ensures straightforward integration into existing smart home or commercial systems.
Suitable for
Controlling large household appliances such as electric ovens, water heaters, or HVAC units
Switching and monitoring motors, pumps or industrial single‑phase loads within the specified voltage and current limits
Integration into smart home or building automation platforms that support MQTT, HTTP/S, WebSocket or KNXnet/IP
Energy monitoring and load management to reduce consumption and avoid overloads
When it may not be suitable
This relay is intended for single‑phase AC loads within 110–240 V and a maximum continuous current of 25 A. It is not designed for DC switching applications or for three‑phase loads without appropriate external wiring and protection. Projects requiring UL/CSA certifications or specific local regulatory approvals should verify compliance before installation.

Protection features: overvoltage protection with auto recovery, overpower protection
Connectivity: Wi‑Fi and Bluetooth; supports MQTT, WebSocket, HTTP/S, UDP, TLS and webhooks
Control options: scripting and virtual components supported
Form factor: compact enclosure with large terminals and included wall mounting anchors/bracket
Color: White
How to use
Install the Shelly SHELLY\_PBS\_SW40 in a suitable enclosure or mounting location, ensuring secure connection to the single‑phase AC supply and the switched load using the large terminals. Configure network access via the device’s Bluetooth or Wi‑Fi setup process, then complete integration using the Shelly app or by connecting directly with supported protocols such as MQTT or HTTPS. Use the built‑in power metering to monitor load consumption and set automation scripts, webhooks or external platform rules to control switching behaviour and protect the circuit from overloads.
What to consider before purchase
Verify that the connected load does not exceed 25 A continuous current and 6000 W within the 110–240 V range
Confirm the application is single‑phase AC; the device is not intended for DC switching or direct three‑phase control without appropriate wiring
Check local electrical codes and required certifications for installation in commercial or regulated environments
Plan for ventilation and enclosure requirements to dissipate heat when switching high currents
Usage recommendations
Use the relay for controlled switching and energy monitoring of large single‑phase appliances. Configure overcurrent protections and automation rules via the Shelly interface or your automation platform, and perform periodic verification of terminal tightness and enclosure temperature when the unit handles sustained high loads.
