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

BR-7M h\u00f8jenergi modul\u00e6r SPD er designet i henhold til IEC standard.<\/p>\n

Denne model er designet i modulopbygget med fremragende luftt\u00e6t egenskab.<\/p>\n

Den er med 35 mm din skinne, som g\u00f8r den nem at installere.<\/p>\n

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

Det kunne installeres i 275V\/320V AC str\u00f8msystem.<\/p>\n

Dette produkt er s\u00e6rligt velegnet til anvendelse i lynbeskyttelsesklasse A i h\u00f8jrisikoomr\u00e5der for lynnedslag.<\/p>\n

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

Beskytteren er installeret med standard 35 mm spor.<\/p>\n

Beskytteren er forbundet med 4 ~ 35 mm kobbertr\u00e5d.<\/p>\n

Det er ikke n\u00f8dvendigt at justere efter at beskytteren er installeret efter behov.<\/p>\n

Under drift skal du j\u00e6vnligt kontrollere, om modulet er r\u00f8dt; udskift den fejlbeh\u00e6ftede komponent i tide.<\/p>\n
