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

Indikerande f\u00f6nster.<\/p>\n

Designad enligt IEC 61643-11.<\/p>\n

En skyddsanordning som f\u00f6rhindrar blixt\u00f6versp\u00e4nning och transient \u00f6verstr\u00f6m fr\u00e5n att tr\u00e4nga in i str\u00f6mf\u00f6rs\u00f6rjningsledningen fr\u00e5n att st\u00f6ra den normala driften av str\u00f6mf\u00f6rs\u00f6rjningssystemet och elektrisk utrustning.<\/p>\n

H\u00f6gpresterande varistor med termisk fr\u00e5nkopplingsutl\u00f6sningsanordning<\/p>\n

Trefas n\u00e4tsp\u00e4nningsavledare<\/p>\n

Skyddsklass: Typ 1, Klass I<\/p>\n

Parallellt \u00f6versp\u00e4nningsskydd<\/p>\n

\u00d6versp\u00e4nningsomr\u00e5den anv\u00e4nds f\u00f6r att skydda k\u00e4nslig utrustning fr\u00e5n sp\u00e4nningstoppar.<\/p>\n

Med h\u00f6g blixtstr\u00f6msurladdningskapacitet<\/p>\n

Slagurladdningsstr\u00f6mmen f\u00f6r en enkel modul n\u00e5r 25kA (10\/350)<\/p>\n

Typ 1-avledaren kombinerar h\u00f6g prestanda och anv\u00e4ndarv\u00e4nlighet i en enda enhet. Deras elektriska parametrar var klassade f\u00f6r de str\u00e4ngaste kraven inom \u00e5sk- och \u00f6versp\u00e4nningsskyddssystem.<\/p>\n

Imax: 100KA (8\/20)<\/p>\n

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

\u2022 Den \u00e4r till\u00e4mplig p\u00e5 \u00e5skskydd f\u00f6r elsystemet i omr\u00e5den med h\u00f6g \u00e5skrisk (LPZ0B eller gr\u00e4nssnittet mellan LPZ0B och LPZ1).<\/p>\n

\u2022\u00a0L\u00e4mplig f\u00f6r trefas TN-C str\u00f6mf\u00f6rs\u00f6rjningssystem med AC p\u00e5 50 till 60 Hz<\/p>\n

\u2022 Anv\u00e4nds huvudsakligen f\u00f6r \u00f6versp\u00e4nningsskydd p\u00e5 niv\u00e5n TN-C-str\u00f6mf\u00f6rs\u00f6rjningssystem (B).<\/p>\n

\u2022 Vanligtvis installerad i byggnaden i l\u00e5gsp\u00e4nningshuvudf\u00f6rdelningssk\u00e5pet eller l\u00e5gsp\u00e4nningshuvudstr\u00f6mbrytaren.<\/p>\n

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

Den installeras parallellt i huvuddistributionsinloppspanelen vid l\u00e5gsp\u00e4nningsing\u00e5ngs\u00e4nden av transformatorn, f\u00f6rdelningsboxen med lufting\u00e5ng i byggnaden, utomhusf\u00f6rdelningssk\u00e5pet\/f\u00f6rdelningsboxen och andra positioner.<\/p>\n
