low voltage fese holder,fuse base
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 630A
Number of poles: 3P,
Assorted fuse links: NT00 for 160A, NT1 for 250A, NT2 for 400A and NT3 for 630A
