D0-system protective cover MERSEN

The D0 fuse-system is installed in low voltage ditribution units, where fuse-links are accessible to non trained persons and can also be replaced by them. This system is the newest generation of screw fuse-system in the german DIN standard and is designed for 400VAC/250VDC networks. The D0 fuse-bases are available in the sizes D01, D02 and D03. D0 fuse-bases are used in combination with D0 fuse-links for the protection of cables and power lines. D0 fuse-links limit and cut-off unacceptable overcurrents and short circuit currents up to their nominal breaking capacity. They also protect equipments and installations against dynamic effects of high short circuit currents. DIN VDE 0636-3, DIN EN 60715
