BR-25M 1P \u00e4r en typ 1+2+3 AC \u00f6versp\u00e4nningsskyddsenhet utformad f\u00f6r att skydda vid ing\u00e5ngen till den elektriska installationen.<\/p>\n

Det finns en termisk avst\u00e4ngningsdel inuti skyddsanordningen, n\u00e4r enheten \u00e4r \u00f6verstr\u00f6m eller \u00f6versp\u00e4nning, kommer den termiska avst\u00e4ngningselementet automatiskt att separeras fr\u00e5n \u00f6versp\u00e4nningsskyddet fr\u00e5n det elektriska n\u00e4tverket, och indikeringsf\u00f6nstret blir r\u00f6tt fr\u00e5n gr\u00f6nt.<\/p>\n

Denna SPD \u00e4r s\u00e4rskilt anv\u00e4ndbar i ett omr\u00e5de med h\u00f6g blixtdensitet d\u00e4r risken f\u00f6r kraftig \u00f6versp\u00e4nningsstr\u00f6m eller till och med direktnedslag \u00e4r h\u00f6g (t.ex.: byggnader utrustade med \u00e5skledare).<\/p>\n

Enligt EN 61643-11 & IEC 61643-1<\/p>\n

BR-25M 1P \u00e4r enpolig SPD.<\/p>\n

Upp: \u22641,3kV.<\/p>\n

Standardiserad 35mm Din-skena montering, kompakt bistabil skena fast sp\u00e4nne, l\u00e4tt att demontera.<\/p>\n

Skruvterminalanslutning, \u00e5tdragningskraft motsvarande dubbelt s\u00e5 h\u00f6g standard, g\u00f6r anslutningen\u00a0mer tillf\u00f6rlitlig och\u00a0s\u00e4krare.<\/p>\n

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

Anv\u00e4nds i v\u00e4xelstr\u00f6msledning av hus, bank, telekomtorn och s\u00e5 vidare.<\/p>\n

L\u00e4mplig som f\u00f6rsta steg av skydd i inkommande str\u00f6mf\u00f6rs\u00f6rjningspaneler och omr\u00e5den med st\u00f6rre exponering f\u00f6r atmosf\u00e4ren, d\u00e4r installationer vanligtvis \u00e4r f\u00f6rsedda med ett externt \u00e5skskyddssystem.<\/p>\n

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

25kA \u00f6versp\u00e4nningsskyddet p\u00e5 f\u00f6rsta niv\u00e5n ska installeras i en vattent\u00e4t milj\u00f6 och fri fr\u00e5n v\u00e5ldsamma vibrationer.<\/p>\n

Se till att den maximala kontinuerliga arbetssp\u00e4nningen f\u00f6r \u00f6versp\u00e4nningsskyddet uppfyller de faktiska kraven.<\/p>\n

Ledningen som ansluter \u00f6versp\u00e4nningsskyddet b\u00f6r vara s\u00e5 kort och rak som m\u00f6jligt, och den totala l\u00e4ngden p\u00e5 ledningen b\u00f6r kontrolleras inom 0,5 meter.<\/p>\n

Innan du sl\u00e5r p\u00e5 str\u00f6mf\u00f6rs\u00f6rjningen, kontrollera om kabeln \u00e4r ordentligt ansluten till kabelanslutningen och om jordningen \u00e4r tillf\u00f6rlitlig.<\/p>\n
