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 frequency 50Hz AC, Rated current up to 630A, Compliant with Gb13539 and IEC60269.
Design Features
There are two kinds of structures for this type of fuse bases; One is made up with fuse carrier, The bolting fuse link is
installed to the carrier, 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.
