    Feature

    Zinc oxide without spark gap with synthetic cover.
    ?Varistors have the ability to instantly switch from an insulating state to a conductive state in the event of an overvoltage,
    ?The composite structure in fiberglass impregnated with epoxy resin ensures the mechanical strength of the stack,
    ?The outer silicone elastomer shell provides dielectric strength.
    Reference standards:IEC 60099-4 - 10 kA,20kA / class 2~4, IEC 60815 - pollution level IV
