Cet appareil pr\u00e9sente une structure int\u00e9gr\u00e9e innovante qui combine un sectionneur et un disjoncteur, ce qui simplifie consid\u00e9rablement son installation et son entretien. Gr\u00e2ce \u00e0 l'utilisation d'une chambre \u00e0 vide pour l'extinction de l'arc, il garantit un haut niveau de s\u00e9curit\u00e9, des performances stables et la capacit\u00e9 d'interrompre des courants de court-circuit allant jusqu'\u00e0 20 kA, r\u00e9pondant ainsi aux normes rigoureuses de la norme GB\/T1984-2014.<\/p>\n<h3><span style=\"font-size:
