Screw Fuse Base

Supporters for D01-D03, DII~DIII fuses of all applicationkinds (gG, aM, aR) in electric lines (type gG) are capable of working.. Screw Fuse BaseApplicationsSupporters for D01-D03, DII~DIII fuses of all applicationkinds (gG, aM, aR) in electric lines (type gG) are capable ofworking under the heat caused by rated current and prospectiveshort-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. Design FeaturesThis series of fuses bases are made up of fuse carrier andsupporter. Insert the fuse into the carrier, which will be screwedinto the supporter to form a complete screw fuse unit. There is atransparent glass window on the top of the fuse carrier, throughwhich the status of the fuse can be easily observed. It can be screwinstalled or rail installed. (Figures 1~13).
