Low voltage Surge Arrester Code (l = 0,5 m) Code (l = 1,0 m) Characteristics MOSIPO is a low voltage metal oxide surge arresters with silicone coating. They are designed to be installed in LV power lines or in junction boxes up to 1 kV as the first level of protection against direct lightning strikes 20 66 20 20 66 21 The disconnecting device reacts after a certain number of strokes when in normal operation the current through the surge arrester increases over 1 mA or in case of atmospheric discharge (current bigger than 65 kA). Technical specification tA < 25 ns T = -40°C ... +85°C IP 67 silicone LSR grey IEC 61643-11 II H07V-K 440/585V 2,0 kV 3200 J 0,0950 kg 0,1230 kg General data Response time: Ambient temperature range: Ingress protection level: Coat: Silicone colour: Tested according to standard: IEC class: Earthing conductor Technical characteristics Uc (AC/DC) Up W Weight (l = 0,5 m) Weight (l = 1,0 m) Standard packing: 100 pcs/box Extra packing: 3 pcs/box The position for installing NNO and MOSIPO surge arresters is decided by directives and technical regulations. They must be installed: - on all branches and ends of low voltage overhead power lines, Limbuska cesta 2 2341 Limbus Slovenia, EU

- at a maximum mutual distance up to 1000 m, - at a distance smaller than 500 m, where storms occur more often, - in all passages from free conductors to cables and vice versa.
