The D01 fuse system represents the latest development in screw systems adhering to the German DIN standard. This system encompasses sizes D01, D02, and D03. Specifically, the D0 ultra-fast acting 'gR' range is tailored for semiconductor protection, particularly in settings where fuse links are accessible to individuals without specialized training, enabling them to change the fuses independently. These fuses are suitable for safeguarding components such as diodes, thyristors, and AC/DC motor drives. The designation 'R' is derived from the term Rectifier.

D0 fuse-links are available with a rated current range from 2A to 100A. Notably, the D01 variant features an ampere rating of 6A and a rated voltage of 440V for both AC and DC applications. Its maximum breaking capacity reaches up to 100 kA, ensuring effective interruption of fault currents. The fuse has a product diameter of 0.43 inches and a power dissipation of 2.3W at its rated current. The melting I²T value is 5 A²s and the clearing I²T at rated voltage is 10 A²s. Constructed from ceramic insulating material, it is mounted using a clip for secure installation.
