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

Denna spd \u00e4r moduldesign, bra t\u00e4tningsprestanda, matchat fj\u00e4rrsignalgr\u00e4nssnitt och felaktigt indikatorf\u00f6nster, installerad i 35 mm DIN-skena, l\u00e4tt att koppla.<\/p>\n

Det har temperaturkontrollteknik, \u00f6verstr\u00f6mss\u00e4kring och termisk str\u00f6mbrytare, automatisk utl\u00f6sning vid f\u00f6rs\u00e4mrad.<\/p>\n

Olika specifikationer tillfredsst\u00e4ller, l\u00e4tta att underh\u00e5lla, kan leverera olika arbetssp\u00e4nningsniv\u00e5er och blixtstr\u00f6m, kan ocks\u00e5 anpassas enligt olika krav.<\/p>\n

Stor fl\u00f6deskapacitet, l\u00e5g restsp\u00e4nning, snabb svarshastighet, n\u00e4r den automatiska utl\u00f6sningen f\u00f6rs\u00e4mras, visuella instruktioner f\u00f6r att \u00f6vervaka f\u00f6nstret i r\u00f6tt.<\/p>\n

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

BR-7M AC SPD anv\u00e4nds l\u00e4mpligen i TN-S 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
