Applications

• Supporters for bolting fuses in electric lines are capable of working under the heat caused by rated current and prospective short-circuit impacting current up to 100KA.
• Rated insulation voltage up to 1000V; Working frequency50Hz AC; Rated current up to 630A. Compliant with GB13539 andIEC269.

Design Features

• There are two kinds of structures for this type of fuse bases: One is made up with fuse carrier, supporter/base (Figure 12.1).The bolting fuse link is installed to the carrier, and then it is inserted to static contacts of the supporter/base. There is no carrier for the other structure, where the bolting fuse is directly installed to the static contacts of the supporter/base. The company can also produce other non-standard bases at the customers’ requirements
