Surge Protection Device

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

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,
