DRO-160 type fuse type isolating switchDetailed product description：

The purpose and characteristics of DRO-160 fuse type isolating switch:

DRO-160 fuse type isolating switch (hereinafter referred to as the switch) has a rated insulation voltage of AC 50Hz, 690V, a rated working voltage of 660V, and a rated current of 160A. It is mainly used as a power switch, isolating switch, and emergency switch in circuits with high short-circuit current and motor circuits.
The rated limit of the switch is the expected short-circuit current (effective value) of 380V~500V/100KA, 660V/50KA.
The switch complies with national standards GB/T14048.1 and GB14048.3, as well as International Electrotechnical Commission standards IEC947 and IEC947-3.
The switch consists of a base and a cover (melting device), with a three-phase semi enclosed structure. It can be operated from the front, and the rated data of the installed fuse link and the action status of the indicator can be directly observed through the transparent plate on the cover. The switch can be equipped with NH000 or NH00 fuse links. Switches have the advantages of small size, safe and reliable use, easy installation and removal of fuse links, and low tactile and operational force.
