    PRODUCT OVERVIEW
    
		    
    NYGQ1Z series self-recovery over-voltage and under-voltage protector is installed in the circuit to detect changes in voltage parameters of the electrical equipments. When the voltage rises above the set value, it can automatically cut off the power supply; when the voltage is recovered to the level below the set value, it can automatically trun on the power supply. It’s commonly used in residential compounds, office buildings, shopping malls, factories and other areas of the electrical system to protect circuits and electrical equipment from the hazards of over-voltage and under-voltage.
