1 Line protection fuses gl-gg IEC parts1, 3 and 3-1 DIN VDE 0636 Parts 10, 30 and 31 Dimensions are stipulated in the following regulations: DIN D Fuse-links DIN D Fuse-links DIN D Fuse-links, long design DIN D Screw caps DIN D Fuse bases DIN D Gauge rings DIN D Screw gauge pieces A, 500 V, 690 V Structure of the D fuse system Like the modern NEOZED system, the D-Fuse system consists of fuse base, gauge piece, fuse link and screw cap. It is designed for a rated voltage of 500V. Noninterchangeability of rated current is guaranteed from one current level to the other above 6 Amps. This is ensured by graduating the diameter of the bottom contact of the fuse-link along with corresponding fixed diameters for the gauge piece. GPEU84
