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

Type:\u00a0T1+T2 Oversp\u00e6ndingsbeskytter<\/p>\n

Svartid: \u2264100ns<\/p>\n

M\u00e6rkede forbindelser.<\/p>\n

Komposit type: 3P+N.<\/p>\n

Montering: standardskinne 35mm.<\/p>\n

Designet til at beskytte elektriske lavsp\u00e6ndingsinstallationer mod elektriske oversp\u00e6ndinger for\u00e5rsaget af koblingsvirkning, lynnedslag og elektromagnetiske impulser.<\/p>\n

I henhold til IEC61643-11.<\/p>\n

Termisk frakoblingsenhed.<\/p>\n

Tilslutning af skrueterminal.<\/p>\n

\n

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

Beskytter elektriske installationer mod direkte lynnedslag og afleder modstr\u00f8mmen fra lyn, der spreder sig fra jordlederen til netv\u00e6rkslederne.<\/p>\n

Enheden er designet til at blive brugt mellem Zone O og Zone 1 (i henhold til IEC 62305-4 definition af lynbeskyttelsesomr\u00e5de).<\/p>\n

Kan bruges til at beskytte et trefaset str\u00f8msystem.<\/p>\n

Sp\u00f8rgsm\u00e5l kr\u00e6ver opm\u00e6rksomhed, n\u00e5r du installerer SPD:<\/strong><\/p>\n

Bestem afladningsstr\u00f8mmens vej.<\/p>\n

Marker de ledninger, der producerer et yderligere sp\u00e6ndingsfald, p\u00e5 enhedens terminal.<\/p>\n

Marker PE-lederen p\u00e5 hver enhed for at undg\u00e5 un\u00f8dvendige induktionssl\u00f8jfer.<\/p>\n

Der etableres en \u00e6kvipotentialforbindelse mellem enheden og SPD.<\/p>\n

Under installationen skal du tilslutte enheden i henhold til installationsdiagrammet, hvor L er faselinjen, N er den neutrale linje, og PE er jordledningen. Forbind ikke enheden forkert.<\/p>\n
