1.Applications

• Supporters for D01-D03, DII~DIII fuses of all application kinds (gG, aM, aR) in electric lines (type gG) are capable of working under the heat caused by rated current and prospective short-circuit impacting current up to 50KA.
• Rated insulate voltage up to 1140V; Working frequency 50HzAC; Rated current 200A. Compliant with GB13539.1, GB13539.3, GB13539.5 and IEC 269-1, IEC269-3.

2.Design Features

•  This series of fuses bases are made up of fuse carrier and supporter. Insert the fuse into the carrier, which will be screwed into the supporter to form a complete screw fuse unit. There is a transparent glass window on the top of the fuse carrier, through which the status of the fuse can be easily observed. It can be screw installed or rail installed. (Figures 1~13).
