Product Description

Products Description

HR17 series fuse type isolating switch,rated insulating voltage AC800V,rated operaing voltage 690V.400V,rated frequency 50Hz,the rated 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 swictch is not used to operate the single motor.

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

This product is in coformlty with standard GB14048.3-2002,IEC60949-3(1999).

Model Explanation

Features

The srture is there pole insulating,the enclousure is made of high strength fire-resistance materials with high insulating
protection. The handleon the base is safe for use and convenient for operating. The transparent panel can be used examine the working condition,the cover is easy totake off and the fuse is

The switch with advance designed contact system,wheb the switch break loaded,current will move to arcing corner,the arcing chamber canassure the reliable making and breaking and protective the contact without ablation,the bthe switch

The type of installation is fixed and hanging types,when install as hanging type,power installed to inlet terminal thrugh the button of switch,When installed as fixed type,the inlet and outlet terminal can be connected with bus bar,and also can be

Parts of the switch adopt the plug type and convenient for maintain and repair,when a frame type or mccb installed,When
