Drag:<\/strong><\/p>\n

Polnummer: 1P,2P,3P,4P,1+1NPE,3+1NPE<\/p>\n

Kraftfulla komponenter, l\u00e4mpliga f\u00f6r alla typer av vanliga kraftsystem.<\/p>\n

Kan anv\u00e4ndas i TN-S system<\/p>\n

\u00d6versp\u00e4nningsavledaren uppfyller kraven i IEC61643-11<\/p>\n

Enheten \u00e4r utformad f\u00f6r att anv\u00e4ndas mellan zon O och zon 1 (enligt IEC62305-4 definition av \u00e5skskyddsomr\u00e5de).<\/p>\n

Produkten anv\u00e4nds huvudsakligen f\u00f6r klass I-skydd av elsystemet.<\/p>\n

Produkten \u00e4r huvudsakligen 10\/350 v\u00e5gform, upp till 25KA<\/p>\n

Installerad i huvudstr\u00f6mf\u00f6rdelningen<\/p>\n

Ans\u00f6kan:<\/strong><\/p>\n

\u2022 Produkten anv\u00e4nds huvudsakligen f\u00f6r prim\u00e4rt skydd av kraftsystemet.<\/p>\n

\u2022 Applikationsoptimerad och f\u00f6rkopplad kombinerad \u00e5skstr\u00f6ms- och \u00f6versp\u00e4nningsavledare f\u00f6r TN-S-system.<\/p>\n

\u2022 Installerad i huvudstr\u00f6mf\u00f6rdelningsboxen.<\/p>\n

\u2022 Van vid industri och automation, kommersiella och bostadsinstallationer, telekom & IT & datacenter, vattenrening, smart grid & LV-m\u00e4tning, solceller och vind mm.<\/p>\n

Installation:<\/strong><\/p>\n

\u2022 Str\u00f6mmen m\u00e5ste st\u00e4ngas av f\u00f6re installation. Livedrift \u00e4r f\u00f6rbjuden.<\/p>\n

\u2022 Det rekommenderas att en s\u00e4kring eller str\u00f6mbrytare ansluts i serie vid \u00f6versp\u00e4nningsskyddets fr\u00e4mre \u00e4nde.<\/p>\n

\u2022 SPD installeras parallellt vid str\u00f6mf\u00f6rs\u00f6rjningens inlopps\u00e4nde av byggnadsf\u00f6rdelaren eller utrustningsrummet. Produkten \u00e4r installerad i typ styrskena. Om f\u00f6rh\u00e5llandena till\u00e5ter kan anslutningsl\u00e4get f\u00f6r Kevin anv\u00e4ndas.<\/p>\n

\u2022 Anslut enheten under installationen enligt installationsschemat, d\u00e4r L \u00e4r faslinjen, N \u00e4r neutrallinjen och PE \u00e4r jordlinjen. Koppla inte bort enheten. N\u00e4r installationen \u00e4r klar, sl\u00e5 p\u00e5 den automatiska str\u00f6mbrytaren och kontrollera om arbetsstatusen \u00e4r normal.<\/p>\n

\u2022 N\u00e4r SPD anv\u00e4nds, kontrollera statusen f\u00f6r feldisplayen regelbundet. Om felvisningsf\u00f6nstret \u00e4r r\u00f6tt eller om fj\u00e4rrterminalen avger en larmsignal, indikerar det att SPD:n \u00e4r felaktig och b\u00f6r repareras eller bytas ut i tid.<\/p>\n

\u2022 L\u00e4mplig f\u00f6r inomhusdrift, s\u00e5som installerad utomhus, m\u00e5ste vara utrustad med vattent\u00e4tt skal.<\/p>\n
