Description
WTH­-SG/RJ45 series surge protective devices are applied to surge protection for data communication systems.
WTH-SG/RJ45-KG series 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.
(Standards compliance: IEC61643­-21, UL497B, IEEE 802.3af PoE/802.3 at PoE Plus)
