Caract\u00e9ristiques:<\/strong><\/p>\n

Parafoudre modulaire et enfichable.<\/p>\n

Parafoudre de type 1+2 selon EN 61643-11.<\/p>\n

Capacit\u00e9 de protection contre le courant de foudre 12,5 kA (10\/350us) par p\u00f4le.<\/p>\n

Indication d'\u00e9tat de fonctionnement\/de d\u00e9faut par un drapeau indicateur vert\/rouge dans la fen\u00eatre d'inspection.<\/p>\n

La signalisation \u00e0 distance peut \u00eatre s\u00e9lectionnable.<\/p>\n

Convient universellement aux syst\u00e8mes TT.<\/p>\n

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

Pour la protection g\u00e9n\u00e9rale des grandes installations et la protection des petites installations avec protection externe contre la foudre.<\/p>\n

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

Avant l'installation, il convient de v\u00e9rifier si le parasurtenseur est intact. S'il est endommag\u00e9 ou si la fen\u00eatre d'affichage est rouge, il ne peut pas \u00eatre utilis\u00e9\u00a0; si la fen\u00eatre est verte, c'est normal.<\/p>\n
