The D0 fuse-system is installed in low voltage distribution units, where fuse-links are accessible to non trained persons and can also be replaced by them. NEOKIT fuse-disconnector size D01, 16A is designed for 400VAC application. D0 fuse-disconnectors are used in combination with D0 fuse-links gG for the protection of cables and power lines. They limit and cut-off unacceptable overcurrents and short circuit currents up to their rated breaking capacity. D0 fuse-links gG also protect equipments and installations against dynamic effects of high short circuit currents.
