The ZoneBarrier Ethernet,4PPOE range of SPDs represents the leading edge design in the protection of network ethernet equipment for a full range of ethernet applications from 10 baseT to 1000 baseT and to the highest power requirements of 4 pair POE. Recent years the application of POE has expanded and the latest standard IEEE802.3 bt allows power over 4 pairs of ethernet cable upto 90W. ZoneBarrier SPD meets the POE requirements to Type 1 &Type 2 according to IEE802.3 and Type3 & Type 4 POE according to IEEE802.3bt uses all 4 pairs in an Ethernet cable to deliver power and data over the same medium up to 90W,

surge protection products effectively reduce the interference coupling that can occur due to transient surge voltages, even significantly below the limits prescribed by insulation co-ordination according to EN 60664-3 / DIN VDE 0110-3. This means that the whole installation is exposed to fewer malfunctions. The arresters are co-ordinated using technical means. This means that decoupling between Types I, II and III is unnecessary. The arresters are tested according to product standard IEC 61643-11 / DIN EN 61643-11 and can be installed in systems according to IEC 61643-12 / VDE 0675-6-12 and IEC 62305-4 / VDE 0185-4. This lightning and surge protection device is suited for installation in power supply systems. Weidmüller offers different products depending on the particular mains network type and voltage level. A special Type I and Type II protective device is even available for photovoltaic

Type III surge protection • Compact Type III arrester for AC/DC protection acc. to IEC 61643-11:2012 • Suitable for protecting terminals • Installed in the vicinity of the equipment to be protected • Can be used as single-port arrester when nominal current is greater than 16 A
