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

Indikerende vindue.<\/p>\n

Designet i henhold til IEC 61643-11.<\/p>\n

En beskyttelsesanordning, der forhindrer lynoversp\u00e6nding og transient overstr\u00f8m i at tr\u00e6nge ind i str\u00f8mforsyningsledningen i at forstyrre den normale drift af str\u00f8mforsyningssystemet og det elektriske udstyr.<\/p>\n

H\u00f8jtydende varistor med termisk frakoblingsudl\u00f8ser<\/p>\n

Trefaset vekselstr\u00f8msoversp\u00e6ndingsafleder<\/p>\n

Beskyttelsesklasse: Type 1, Klasse I<\/p>\n

Parallel oversp\u00e6ndingsbeskyttelsesanordning<\/p>\n

Oversp\u00e6ndingsomr\u00e5der bruges til at beskytte f\u00f8lsomt udstyr mod sp\u00e6ndingsspidser.<\/p>\n

Med h\u00f8j lynstr\u00f8msafladningskapacitet<\/p>\n

Slagafladningsstr\u00f8mmen for enkelt modul n\u00e5r 25kA (10\/350)<\/p>\n

Type 1-aflederne kombinerer h\u00f8j ydeevne og brugervenlighed i en enkelt enhed. Deres elektriske parametre blev vurderet til de strengeste krav inden for lyn- og oversp\u00e6ndingsbeskyttelsessystemer.<\/p>\n

Imax: 100KA (8\/20)<\/p>\n

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

\u2022 Den kan anvendes til lynbeskyttelse af elsystemet i omr\u00e5der med h\u00f8j lynrisiko (LPZ0B eller gr\u00e6nsefladen mellem LPZ0B og LPZ1).<\/p>\n

\u2022\u00a0Velegnet til trefasede TN-C str\u00f8mforsyningssystemer med AC p\u00e5 50 til 60 Hz<\/p>\n

\u2022 Anvendes hovedsageligt til TN-C-str\u00f8mforsyningssystem (B) niveau oversp\u00e6ndingsbeskyttelse<\/p>\n

\u2022 Generelt installeret i bygningen i lavsp\u00e6ndings hovedfordelingsskab eller lavsp\u00e6ndings hovedafbryder.<\/p>\n

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

Den er installeret parallelt i hovedfordelingsindgangspanelet ved lavsp\u00e6ndingsindgangsenden af \u200b\u200btransformeren, fordelerboksen med overliggende indgang i bygningen, det udend\u00f8rs fordelerskab\/fordelingsboks og andre positioner.<\/p>\n
