The TOMZN TO-MPD-63LW is a multifunctional WiFi-controlled smart relay designed for installation in electrical panels. The TOMZN PD-63LW enables remote phase control (max. 63 A), scheduling, versatile measurements (voltage, current, energy), and protection functions (leakage current, overvoltage, overload). The device features an informative LCD display, indicator lights, and control and programming buttons.

The TOMZN PD-63LW connects wirelessly to a cloud service via WiFi at the installation site. Remote control, monitoring, and alarm reception are done through the free Tuya mobile app (supports Android and iOS), which can be easily integrated with other automation systems such as Google Home, Amazon Alexa, and IFTTT.
