Surge Protective Device
Description
WTH -SG/RJ45 Series surge protective devices are applied to surge protection for data communication systems.
WTH-SG/RJ45-KG is connected in series in CAT6 network cables, compatible with 10/100/1000/10000 (10G) Base-T
Ethernet systems, protecting the equipment which are connected to the network (e.g. computers, routers, PoE devices,
etc.) against damages by over-voltage surge.
