The D fuse-system represents the initial generation of screw fuse-systems adhering to the German DIN standard, which remains prevalent in various installations. This system encompasses sizes DII, DIII, DIV, and DV. The ultra-fast acting “gR” variants are specifically designed for semiconductor protection in scenarios where fuse-links may be accessed and replaced by untrained personnel.

These fuse-links are vital for safeguarding components such as diodes, thyristors, and AC/DC motor drives. The designation “R” refers to Rectifier, highlighting their application focus. The D fuse-links are rated for a current range from 2A to 200A. The RECTICUR DIV fuse-link operates at an ampere rating of 80 A and a rated voltage of 500 V AC and 440 V DC. It features a maximum breaking capacity of 100 kA and has a product diameter of 1.46 inches. At its rated voltage, the clearing I2T is 7300 A²s, while the melting I2T is recorded at 3200 A²s. Additionally, it dissipates 18 W of power at the rated current value, and is manufactured with a ceramic insulating body.
