Utrustad med termisk fr\u00e5nkoppling.<\/p>\n

BR-7M 3P \u00e4r byggd med en plug-in modul och fast bas, vilket m\u00f6jligg\u00f6r ett enkelt och snabbt underh\u00e5ll.<\/p>\n

DIN-skena monterat \u00f6versp\u00e4nningsskydd \u00e4r l\u00e4tt att installera i vilken standardiserad distributionsruta eller kontrollsk\u00e5p som helst.<\/p>\n

Den \u00e4r utrustad med en intern termisk s\u00e4kerhet som kommer att koppla bort enheten fr\u00e5n AC-n\u00e4tverket om den skulle ta slut. Denna fr\u00e5nkoppling kommer att indikeras av att den r\u00f6da mekaniska indikatorn t\u00e4nds p\u00e5 framsidan.<\/p>\n

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

BR-7M AC SPD anv\u00e4nds l\u00e4mpligen i TN-C str\u00f6mf\u00f6rs\u00f6rjningssystemet AC 50\/60HZ.<\/p>\n

L\u00e4mplig f\u00f6r systemstr\u00f6mskydd, s\u00e5som elf\u00f6rdelningssk\u00e5p, kopplingssk\u00e5p, kopplingssk\u00e5p, AC-f\u00f6rdelningstavla, etc.<\/p>\n

SPD f\u00f6r att skydda fr\u00e5n direkta och indirekta blixtar och andra transienta \u00f6versp\u00e4nningar.<\/p>\n

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

Skyddet \u00e4r installerat med standard 35 mm sp\u00e5r.<\/p>\n

Skyddet \u00e4r anslutet med 4 ~ 35 mm koppartr\u00e5d.<\/p>\n

Inget behov av att justera efter att skyddet har installerats efter behov.<\/p>\n

Under drift, kontrollera regelbundet om modulen \u00e4r r\u00f6d; byt ut den felaktiga komponenten i tid.<\/p>\n
