Application Range
WTH-GR series triad Integrated surge protective devices are applied to surge protection of power, control signal, BNC video signal or RJ45 Ethernet. With characteristics of low voltage, quick response, etc, they can release and prevent the damage to the protected device arising from inductive surge from power and control wire or the other surge overvoltage. They are widely used in the field of security monitoring system, CCTV system, POE system, dataroom and so on.
(Standards compliance: IEC 61643-1, IEC61643-21)

Main Features
