Surge Arresters 40ka Surge Protectors

IntroductionSP5 series surge protection devices are suitable for all levels of lightning protection areas under AC 50/60Hz, 230/400V TT, IT, TN-S, TN-C, TN-CS and other power supply systems, and can discharge up to 100KA lightning overcurrent.Installation should be installed as close as possible to the upstream line end of the protected equipment, and connect the outer conductor (L) or neutral line (N) to the grounding device of the customer's equipment. If the installation distance cannot be guaranteed, additional installations are required between all levels of protectors. Decoupling components, adding an inductor in low-voltage power supply system can achieve the purpose of decoupling.Product FeaturesNew designed cases;Low residual voltage of impulse current, high withstand capacity;Fast response time less than 25ms;Stable integrated base, modular design with hot-plug;Indication window color shows SPD status; (Green for normal, red for fault)35mm Rail mounting, match most general installation requirements.ApplicationFor civil applicationFor industrial application Technical DataItemSP5-10SP5-20SP5-40SP5-60SP5-80Nominal discharge current  In(8/20us)5KA10KA20KA30KA40KAMax discharge current  In(8/20us)10KA20KA40KA60KA80KAMax. continuous operating voltage  Uc (V)270320385420270320385460270320385460270320385460270320385460Varistor voltage  U1mA (V)430510620680430510620710430510620710430510620710430510620710Protection level      Up (kA)1.01.21.21.21.01.41.61.81.21.61.82.01.51.82.02.21.61.82.22.3Poles1P, 2P, 1P+N, 3P, 4P, 3P+NRated working voltage   Un(V)230/400Response time (ms)≤25Test classificationClass IIIP protection classIP20Flame classV0Case materialPBT/PA66Recommended fuse or circuit breaker (A)40∽60Installation method35mm DIN rail mountingStandardsGB/T 18802.11    IEC61643-11Dimensions /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
