DNH1 series fuse-switch-disconnector (chere inafter refered to switch) is designed for the distribution circuit and electromot of circuit with high short circuit current, with rated AC voltage 400v and 690V, conventional thermal current up to 630A. It is used as power switch, switch disconnector and emergent switch, and with the function of circuit protection, but not used as a direct open or close single electromotor popularly. The low-voltage cabinets that are compatible are mostly concentrated in industrial and civilian power distribution scenarios, as follows: GGJ single-phase/small compensation cabinets, small power distribution cabinets, comprehensive distribution boxes (JP cabinets), civilian/small industrial JP cabinets,
This product is in conformity with standard GB14048.3(idt IEC60947-3).
