1.Note: This product is a smart WiFi switch with over-current protection, overvoltage protection, undervoltage protection, overpower protection, and CPU temperature protection, but no short circuit protection. It is recommended to use it with a circuit breaker. Complies with IEC 60947 standard 2.Applicable Current Scenarios: AC-1, applied to circuits controlling heaters, incandescent lamps, ovens, and other purely resistive loads; Max Wiring Capacity: Power side: 10 mm²; Load side: 10 mm²; Type: Latching relay, capable of carrying high current; Poles Description:1P+N, N pole cannot be cut off 3.Real-time Power Monitoring (AC Electricity Positive Import) and Management: (1) Analyze the real-time electricity consumption, real-time current, real-time voltage, and real-time power of connected devices, and record historical power consumption (by hour, day, month, and year). Also can export power consumption data via email. (2) Clear Electricity Data. (3) There are functions to display the current remaining electricity, prepaid switch, and clear the remaining electricity, which facilitates comprehensive electricity management. 4.Local Control: (1) Even no wifi, you can set the parameters and functions through the 3 buttons on the smart wifi switch. (2) Password can be set to prevent unauthorized access and modification 5.Multiple Reclosing Functions: There are overcurrent reclosing, overpower reclosing and overvoltage and undervoltage reclosing functions. Please note that after overcurrent/overpower protection, the device will attempt 3 reclosures. If overcurrent/overpower persist, no further reclosure will occur. After overvoltage and undervoltage protection, the device will automatically reclose. Closing threshold: overvoltage threshold -15 V, undervoltage threshold +15 V. 6.Screen Display: Smart switch with LCD color backlit display, clear and easy to read data. Adjustable 1-5 levels of brightness and directional.
