Smart Leakage Protection Switch with WiFi Control

Three phase four wire WiFi multifunctional leakage protection intelligent switch   This three-phase four wire WiFi IoT intelligent switch is a multifunctional power distribution device that integrates monitoring, protection, and control. It is compatible with 380V+N three-phase four wire power supply and has a working current range of 1A to 80A, making it highly versatile. The device integrates multiple electrical protection functions and is equipped with over temperature, short circuit, leakage, and current limiting protection modules, which can monitor real-time electricity consumption data such as power, voltage, current, and operating power. The device comes with a fault memory function, which can quickly shut down and trip in case of circuit abnormalities, and retain fault records for easy troubleshooting by operation and maintenance personnel, avoiding potential hazards of secondary power consumption. The integrated structural design does not require the installation of extra ac…
