The D0 fuse-system is specifically configured for low voltage distribution units, where fuse-links can be accessed and replaced by untrained personnel. This system represents the latest generation of screw fuse systems adhering to German DIN standards, accommodating voltages of 400VAC and 250VDC. Available sizes include D01, D02, and D03, which are utilized alongside D0 fuse-links to protect cables and power lines.

D0 fuse-links serve a critical role in limiting and disconnecting unacceptable overcurrents and short circuit currents, up to their specified nominal breaking capacity. These components also provide essential protection for equipment and installations against the dynamic effects caused by high short circuit currents. The system is compliant with DIN VDE 0636-301 and DIN EN 60715 standards, ensuring reliable performance in various applications such as house incoming units, meter distribution units, distribution cabinets, installation cabinets, and fuse boxes.
