Moreover, because of PoE feature it ALLOWS PoE enabled devices to remain powered while still protected against damaging -strikes or voltage spikes.Material: plastic + metalColor as shownFeaturesFast energy absorption on over-voltageLow resistance and minimal capacitance - minimal influence on data linkEasy in-line installation: two RJ45 female connectorsSpecificationProduct Name: Gigabit POE Network -ProtectorProtection object: POE network switch, POE camera, terminal with POE power supply functionInterface: RJ45Response time Less than 1nsRated operating voltage: 48VTransfer rate: 1000MbpsContinuous operating voltage: 57VWorking temperature: -30 ~ 70 degrees CelsiusOperating humidity: 30%-90%Please notes:Two things are crucial and should NOT be missed when using the Ethernet surge protector.Correct positioning: IN jack on the unprotected part of cable and OUT jack on the protected side of cable.Reversed installation will still allow network traffic and operation but there will be no-/surge protection at all!proper grounding: please note the yellow/green ground wire. This wire must be connected to proper electrical ground in the building.Ask a qualified electrician about such grounding or search the Internet for information.Without proper grounding the surge protector will be unable to drain the excess voltage and will be ineffective!Package Contents:2 x POE Network -Surge Protection DeviceOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
