1、Voltage Monitoring: Over and under voltage protector realtime monitoring of over and under voltage, when the voltage is unstable, higher than the set value or set value, the protector will trip in 2 seconds for protecting. 2、Current Monitoring: Over and under voltage protector line current realtime monitoring, overcurrent protection, realtime monitoring of load current and power after connection, when the load current is greater than the set value, the protector trips for protection. 3、Leakage Protection: Overvoltage protector in the line leakage current, realtime monitoring, automatic and accurate monitoring of the current leakage current in the line after the device is connected, if more than the set leakage current, the device cuts off the power supply within 0.1 seconds. 4、Adjustable Parameters: All the protections of over under voltage protector can be adjusted, over voltage, under voltage, overload, leakage, over temperature, overload delay, the number of reclosing times can be adjusted by itself. 5、Lightning Protection: The under voltage protector can direct the surge current generated by the line to the earth when lightning strikes, and the equipment has a lightning protection levels of 10KA to prevent the equipment at the load end from being damaged. 6、Automatic Reclosing: The over under voltage protector can automatically split the gate and close the gate, after the protector alarm trips, after a certain time interval (the first 30S, the second 300S, the 3rd to 50th 600S), after detecting the fault discharged automatically reclosing the power. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
