Tuya Wi-Fi DIN-Rail Switch with Voltage Protection Options

Add app-controlled switching to a compatible DIN-rail circuit with a Tuya device. It is for qualified installers selecting protection and metering functions.

• ✅ Schedule a compatible circuit — The app provides timed switching.
• ✅ Control remotely — A 2.4GHz Wi-Fi connection links the device to Smart Life/Tuya.
• ✅ View electrical data — The metering variant adds current, power and energy readings.
• ✅ Use local controls — The device includes a manual button.

Select voltage-only or metering functionality

V Protect and VA Protect with kWh are different options. The description's current limits differ, so confirm actual rated and adjustable values on the supplied device before circuit design.

Use qualified installation and required upstream protection. App switching and threshold functions do not establish certified circuit-breaker performance; Home Assistant is not supported as stated.
