Product Overview

380V household self resetting over-voltage and undervoltage delay protector (hereinafter referred to as protector) is a new generation of household appliance protection device developed according to the current situation of municipal electricity. It can play a protective role in the case of abnormal voltage. When the mains voltage exceeds or falls below the action voltage value of the protector, the protector can quickly and reliably cut off the load power supply to protect electrical equipment. When the mains voltage returns to normal, the protector will automatically switch on the power supply, restore the power supply, and realize full automatic control. The indicator light on the panel indicates the working state of the protector. The green light is for normal power supply, and the red light is for the protection function to start and cut off the power supply. The utility model has the advantages of simple and convenient use, stable and reliable performance.
Can be installed in parallel with DZ471C45)
