Detailed Product Description

HR17B series fuse type isolating switch

The enclosed structure, has the food insulation protection performance. The transparent work observation, the use safe is reliable, ease of operation freely. Designs the advanced contact system, guaranteed the switch reliable minute breaks, the works is stable. The switch various modules use the plug and socket assembly suitable structure is advantageous for the maintenance overhaul.

Product Usage

HR17 HR17B fuse disconnecter, rated insulating voltage AC 800V, rated operating voltage 690V, 400V, rated frequency 50Hz, the rated current 160A-630A mainly used us 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 with isolation 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 ability, makes the line to isolate uses.

This product is in conformity with standard GB14048.3-2002, IEC947-3(1999)

Construction Characteristic

The structure is three pole insulating, the enclosure is made of high strength fire-resistance materials with high insulating protection. The handle on the base is sage for use and convenient for operating. The transparent panel can be used examine the working condition, the cover is easy to take off and the fuse is simple for isolating switch.

The switch with advance designed contact system, when the switch break loaded, current will move to arcing corner, the arcing chamber can assure the reliable making and breaking and protective the contact without ablation, the both switch can working in a stable condition.

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

Parts of the switch adopt the plug type and convenient for maintain and repair, when a frame type or MCCB installed, when the switch can be used as isolating switch.
