Disjoncteur Masterpact NW12 HF Schneider : La performance d\u00e9brochable pour r\u00e9seaux critiques<\/h2>\n

Le Disjoncteur Masterpact NW12 HF Schneider<\/strong> s’\u00e9tablit comme une r\u00e9f\u00e9rence technologique pour la protection des circuits de forte puissance \u00e9lectrique. Affichant un calibre nominal de 1250A<\/strong> (Ith 1250A \u00e0 55\u00b0C), cet interrupteur-disjoncteur ouvert basse tension g\u00e8re la coupure, l’isolement et la s\u00e9curit\u00e9 des lignes \u00e9lectriques au sein des industries lourdes, infrastructures de sant\u00e9, ou centres de calcul de donn\u00e9es.<\/p>\n

Cet appareil se distingue par sa configuration m\u00e9canique d\u00e9brochable. Contrairement aux versions fixes, le mod\u00e8le d\u00e9brochable coulisse sur des glissi\u00e8res et s’encliquette sur un ch\u00e2ssis gr\u00e2ce \u00e0 un m\u00e9canisme de profil\u00e9s lat\u00e9raux renforc\u00e9s (finition bichromat\u00e9e dor\u00e9e). En fa\u00e7ade, une manivelle d’insertion s’associe \u00e0 un indicateur m\u00e9canique \u00e0 trois positions distinctes : connected<\/em> (connect\u00e9), test<\/em> (position d’essai pour v\u00e9rifier les auxiliaires sans alimenter la puissance), et disconnected<\/em> (d\u00e9broch\u00e9 en toute s\u00e9curit\u00e9 pour extraction compl\u00e8te). Cette technologie est indispensable pour limiter les co\u00fbts li\u00e9s aux arr\u00eats d’exploitation lors des phases de maintenance.<\/p>\n

Performances \u00c9lectriques de la Gamme HF<\/h3>\n

Le code de performance HF<\/strong> indique que ce disjoncteur est calibr\u00e9 pour supporter et interrompre des courants de court-circuit particuli\u00e8rement s\u00e9v\u00e8res. Les sp\u00e9cifications certifi\u00e9es sur sa plaque constructeur avant d\u00e9montrent son endurance :<\/p>\n

    \n
  • Tension assign\u00e9e d’isolement (Ui) :<\/strong> 1000 V<\/li>\n
  • Tension assign\u00e9e de tenue aux chocs (Uimp) :<\/strong> 12 kV<\/li>\n
  • Courant de courte dur\u00e9e admissible (Icw) :<\/strong> 85 kA efficace pendant 1 seconde<\/li>\n
  • Pouvoir de fermeture assign\u00e9 en court-circuit (Icm) :<\/strong> 187 kA cr\u00eate<\/li>\n
  • Pouvoir de coupure de service (Ics) :<\/strong> Qualifi\u00e9 \u00e0 100% Icu, garantissant que l’appareil reste pleinement op\u00e9rationnel m\u00eame apr\u00e8s l’ouverture sur un d\u00e9faut r\u00e9seau majeur.<\/li>\n<\/ul>\n

    Interface Frontale et Commandes<\/h3>\n

    L’ergonomie de ce Disjoncteur Masterpact NW12 HF Schneider<\/strong> offre des organes de commande m\u00e9canique clairs et s\u00e9curis\u00e9s sous plastron isolant :<\/p>\n

      \n
    • Boutons-poussoirs m\u00e9caniques :<\/strong> Commande d’ouverture rouge (Push OFF) et commande de fermeture noire (Push ON).<\/li>\n
    • Indicateurs visuels :<\/strong> Fen\u00eatre de position des contacts principaux (\u00ab\u00a0O OFF\u00a0\u00bb en vert ou \u00ab\u00a0I ON\u00a0\u00bb en rouge) compl\u00e9t\u00e9e par le t\u00e9moin d’\u00e9tat des ressorts d’accumulation d’\u00e9nergie (\u00ab\u00a0Discharged\u00a0\u00bb \/ \u00ab\u00a0Charged\u00a0\u00bb).<\/li>\n
    • Bouton Reset :<\/strong> Un indicateur m\u00e9canique rouge (Reset) permet de r\u00e9armer visuellement l’appareil apr\u00e8s un d\u00e9clenchement sur d\u00e9faut \u00e9lectrique.<\/li>\n<\/ul>\n
