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

Supportable, supporte plusieurs frappes.<\/p>\n

Classe de protection : Type 1+2, Classe I +Classe II.<\/p>\n

BR-50GR 3P convient au syst\u00e8me TN-C.<\/p>\n

Parafoudre 3 p\u00f4les 50kA Type 1.<\/p>\n

boiterie : 50KA sur impulsion de courant 10\/350 \u00b5s.<\/p>\n

Imax : 160 kA\/Phase (forme d'onde 8\/20 \u03bcs).<\/p>\n

Avec fen\u00eatre d'indication et contacts de t\u00e9l\u00e9commande.<\/p>\n

Rail DIN de 35 mm.<\/p>\n

La s\u00e9rie BR-50GR est constitu\u00e9e de dispositifs de protection contre les surtensions de type 1 con\u00e7us pour d\u00e9charger les surtensions \u00e0 courant \u00e9lev\u00e9 sans aucun dommage \u00e0 l'\u00e9quipement \u00e9lectrique de secours.<\/p>\n

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

\u2022 Utilis\u00e9 dans le concept de zones de protection contre la foudre \u00e0 la limite LPZ0B-LPZ1.<\/p>\n

\u2022 Pour prot\u00e9ger les installations des consommateurs basse tension contre les d\u00e9charges indirectes de foudre.<\/p>\n

\u2022 Prot\u00e9ger les \u00e9quipements \u00e9lectriques et \u00e9lectroniques contre les transitoires provenant de la foudre, de la commutation des transformateurs, de l'\u00e9clairage et des moteurs.<\/p>\n

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

Mieux vaut sous la direction d'un \u00e9lectricien professionnel.<\/p>\n

L'onglet vert, \u00e9tat de fonctionnement normal, l'onglet rouge, \u00e9tat d'\u00e9chec, doivent \u00eatre remplac\u00e9s rapidement.<\/p>\n
