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

Oversp\u00e6ndingsafleder for lavsp\u00e6ndingsstr\u00f8mforsyningssystem beskyttelse mod oversp\u00e6nding.<\/p>\n

SPD er velegnet til AC 50\/60HZ, TT str\u00f8mforsyningssystemer.<\/p>\n

Beskyttelsesanordning vedtager 35 mm Din-skinnemontering.<\/p>\n

Designet i henhold til IEC61643-11 og GB18802.1 standarder.<\/p>\n

Da beskytteren normalt fungerer, er pilotlampen gr\u00f8n.<\/p>\n

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

Velegnet til TT-system, til beskyttelse af bygningerne.<\/p>\n

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

Ledningsf\u00f8ring i henhold til m\u00e6rket for oversp\u00e6ndingsbeskyttelse i henhold til ledningsdiagrammet.<\/p>\n

Ved installation i henhold til installationsdiagrammet viser forbindelsen, hvor l (L1, L2, L3) for linjen, n er neutral, PE jordledning, tag ikke fejl. N\u00e5r installationen er fuldf\u00f8rt, skal du kontrollere, at beskyttelsesenheden er tilsluttet, lukke den automatiske afbryderkontakt (sikring), kontrollere, at arbejdsstatus er normal.<\/p>\n

Beskytter i brug under fejlvisningsvinduet b\u00f8r periodisk verificere og se tilstand, n\u00e5r r\u00f8dt fejldisplayvindue eller fjernterminal udsender alarmsignaler, beskytteren svigter, b\u00f8r repareres eller udskiftes rettidigt.<\/p>\n
