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

Ny Iimp 12,5kA \u00f6versp\u00e4nningsavledare.<\/p>\n

Specialdesign f\u00f6r att spara installationsutrymme.<\/p>\n

Den skyddar mot indirekt och direkt blixteffekt eller annan \u00f6verg\u00e5ende \u00f6versp\u00e4nning<\/p>\n

H\u00f6g urladdningsstr\u00f6m.<\/p>\n

SPD-design enligt GB18802.1\/IEC61643-1 standard.<\/p>\n

Indikeringsf\u00f6nster f\u00f6r tydlig visning av SPD-status, varje stolpe med ett indikeringsf\u00f6nster.<\/p>\n

Antal stolpar: 3P+NPE.<\/p>\n

Utbytbar modul.<\/p>\n

Valfri fj\u00e4rrstatussignalering.<\/p>\n

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

F\u00f6r att f\u00f6rhindra att str\u00f6mf\u00f6rs\u00f6rjningsutrustning skadas av \u00f6versp\u00e4nning och blixtnedslag.<\/p>\n

Anv\u00e4nds p\u00e5 byggnader i applikationer d\u00e4r det finns ett externt \u00e5skskyddssystem installerat, vanligtvis installerat vid serviceing\u00e5ngen.<\/p>\n

Anv\u00e4nds ofta i transformatorns l\u00e5gsp\u00e4nningssida som det f\u00f6rsta skyddet av str\u00f6mf\u00f6rs\u00f6rjningen.<\/p>\n

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

Kabeldragning enligt \u00f6versp\u00e4nningsskyddets m\u00e4rke enligt kopplingsschemat.<\/p>\n

N\u00e4r den installeras enligt installationsschemat visar anslutningen, d\u00e4r l (L1, L2, L3) f\u00f6r linjen, n \u00e4r neutral, PE jordledning, missa inte. Efter att installationen \u00e4r klar, kontrollera att skyddsenheten \u00e4r inkopplad, st\u00e4ng den automatiska str\u00f6mbrytaren (s\u00e4kring), kontrollera att arbetsstatusen \u00e4r normal.<\/p>\n

Skydd som anv\u00e4nds under felvisningsf\u00f6nstret b\u00f6r periodiskt verifiera och visa tillst\u00e5nd n\u00e4r r\u00f6tt feldisplay eller fj\u00e4rrterminal avger larmsignaler, skyddet g\u00e5r s\u00f6nder, ska repareras eller bytas ut i tid.<\/p>\n
