Features 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. Current Monitoring: Over and under voltage protector line current realtime monitoring, overcurrent protect, realtime monitoring of load current and power after connection, when the load current is greater than the set value, the protector trips for protect. Leakage protect: 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. 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. light protect: The under voltage protector can direct the current generated by the line to the earth when light strikes, and the equipment has a light protect levels of 10KA to prevent the equipment at the load end from being damaged.
