Key features & benefits

The D0 fuse-system is the most modern of the screw systems in the German DIN standard. This system comprises the sizes D01, D02 and D03.
Those D0 ultra-fast acting “gR” ranges are dedicated to semi-conductor protection, in applications where fuse-links are accessible to non-trained persons and can also be changed by them.
They are used for the protection of components such as diodes, thyristors or AC/DC motor drives. The “R” stands for the English word Rectifier. D0 fuse-links are available at the rated current range from 2A up to 100A.
