GNS1 is applicable to an electric line of AC 50Hz or 60Hz .rated working voltage 380V or less it is used to limit the transient over-voltage amplitude and to absorb,dissipate and discharge the surge current energy.If the product is used in a high-class over-voltage condition,it can degrade the over-voltage class borne by the protected electric element to the next lower class.It is also applicable to form a packaged electric appliance with a modulus terminal electric device,raising the erection class and expanding the application range of the eletric device . If the product is used for the terminal devices, it can further reduce the over-voltage due to improper operation or light-stroke voltage to protect computer and microcomputer and household appliance.
