HR17 fuse switch disconnector,Isolating Switch Fuse Rated voltage: 660V Rated current:160A,250A,400A,630A

HR17 fuse switch disconnector,Isolating Switch Fuse

1. Description:

DNH1(HR17) series NH fuse switch disconnector used for rated current 40A-630A, can be bus type or fixed type, provide upper or lower end connection, with integrated auxiliary closing, arc extinguishing equipment and touch protection parts,  with fuse matched inside. and self-closing test hole in the switch cover. Providing the most safty using.

HR17  fuse type isolation switch,rated insulating voltage AC800V.rated operating voltaged 690V. 400V,rated frequency 50HZ. the rates current 160A~630A mainly used as power switch, isolating switch and emergency switch with function of protection in the circuit with high short circuit current and motor circuit,this switch is not used to operate the single motor.

When isolator knife replace fuse, this switch does not have the electric circuit to overload with short-circuits the protection function,only satisfies the rating which this switch stipulated to put through with the minute breaks the abilitu,makes the line to isolate uses.

this product is coformity with standard GB14048.3-2002.IEC 947-3(1999).

Switch rating heat current: 160A, 250A, 400A and 630ANumber of poles: 3P,Assorted fuse links: NT00 for 160A, NT1 for 250A, NT2 for 400A and NT3 for 630ARated currents: 4, 6, 10, 16, 20, 25, 32, 35, 40, 50, 63, 80, 100, 125, 160, 200, 224, 250, 300, 315, 355, 400, 425, 500 and 630Rated insulation voltage: 690VRated voltage: 400VRated limit short-circuit current: 50kA
