HRC bar isolating switch with 160A fuse switch disconnector

HR17 Fuse-switch Disconnector is applied to under Rated Voltage 690V. The main current is 160A to 630A.It is mainly used as power switch, isolator switch and  emergency switch in power system.

Assorted fuse links: NH00 for 160A, NH1 for 250A, NH2 for 400A and  NH3 for 630A
Rated 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 630    fuse,fuse switch,
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)
