MERSEN - FUS. D - GR DII 500VAC/400VDC 4A

The D fuse-system is the first generation of screw fuse-systems in the German DIN standard. It is still used in many installations. This D system comprises the sizes DII, DIII, DIV, DV. Those D 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. D fuse-links are available at the rated current range from 2A up to 200A.
