\u00d6versp\u00e4nningsskydd av klass B+C.<\/p>\n

Dessa \u00f6versp\u00e4nningsskydd monterade p\u00e5 DIN-skena \u00e4r l\u00e4tta att installera i alla standardiserade distributionsrutor eller kontrollsk\u00e5p.<\/p>\n

Den \u00e4r utrustad med en termisk fr\u00e5nkopplingsanordning och ger felindikatorer i realtid vilket m\u00f6jligg\u00f6r fullst\u00e4ndig drifts\u00e4kerhet.<\/p>\n

Gr\u00f6n\/r\u00f6d f\u00f6nsterf\u00e4rg som visar arbetsstatus, gr\u00f6n=normal, r\u00f6d=onormal.<\/p>\n

Kontinuerlig arbetssp\u00e4nning AC UC 150V\/275V\/320V.<\/p>\n

Installationsmetod 35 mm breda elinstallationsstyrskenor.<\/p>\n

Skalet flamskyddsmedel.<\/p>\n

Inbyggd termisk felutl\u00f6sningsenhet, s\u00e4ker att anv\u00e4nda.<\/p>\n

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

1. Allm\u00e4n f\u00f6rdelningstavla i byggnader<\/p>\n

2. F\u00f6rdelningsl\u00e5da med overhead ing\u00e5ng i byggnader<\/p>\n

3. F\u00f6rdelningssk\u00e5p och f\u00f6rdelningsl\u00e5da f\u00f6r utomhusutrustning med h\u00f6g effekt.<\/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
