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

Klasse B+C oversp\u00e6ndingsbeskytter.<\/p>\n

Disse DIN-skinnemonterede oversp\u00e6ndingsbeskyttere er nemme at installere i enhver standardiseret distributionsrude eller kontrolskabe.<\/p>\n

Den er udstyret med en termisk frakoblingsenhed og giver fejlindikatorer i realtid, hvilket giver fuld driftssikkerhed.<\/p>\n

Gr\u00f8n\/r\u00f8d vinduesfarve, der viser arbejdsstatus, gr\u00f8n=normal, r\u00f8d=unormal.<\/p>\n

Kontinuerlig arbejdssp\u00e6nding AC UC 150V\/275V\/320V.<\/p>\n

Installationsmetode 35 mm brede elektriske installationsstyreskinner.<\/p>\n

Skal flammeh\u00e6mmende.<\/p>\n

Indbygget termisk fejludl\u00f8ser, sikker at bruge.<\/p>\n

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

1. Generelt fordelingstavle i bygninger<\/p>\n

2. Fordelingsboks med overhead input i bygninger<\/p>\n

3. Fordelingsskab og fordelingsboks til udend\u00f8rs h\u00f8jeffektudstyr.<\/p>\n

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

25kA f\u00f8rste niveaus oversp\u00e6ndingsbeskytter skal installeres i et vandt\u00e6t milj\u00f8 og fri for voldsomme vibrationer.<\/p>\n

S\u00f8rg for, at den maksimale kontinuerlige arbejdssp\u00e6nding for oversp\u00e6ndingsbeskytteren opfylder de faktiske krav.<\/p>\n

Ledningen, der forbinder oversp\u00e6ndingsbeskytteren, skal v\u00e6re s\u00e5 kort og lige som muligt, og den samlede l\u00e6ngde af ledningen skal kontrolleres inden for 0,5 meter.<\/p>\n

F\u00f8r du t\u00e6nder for str\u00f8mforsyningen, skal du kontrollere, om kablet er sikkert forbundet til ledningsterminalen, og om jorden er p\u00e5lidelig.<\/p>\n
