Product Description
Applications
This series of fuses are mainly used in circuits of AC 50Hz, rated voltage of 1500V and rated current of 1000 A, to protect the semiconductor components and the whole unit from short-circuit.
The breaking capacity of the fuses is up to 100KA.
The fuses are compliant with the IEC60269-1, IEC60269-4, IEC60269-4-1 and GB/T13539.1, GB/T13539.4, GB/T13539.7.
Design Features
The variable cross-secton fuse element made of pure silver sheets are sealed in the melting tube made of epoxy glass fibre which is heat resistant. The fuse tube is filled with chemically-treated high-prrity quarts as arcextinguishing medium. The two ends of the melting body are connected to the (knife) contacts by dot welding.
