The D0 fuse system is used in low-voltage systems in which the fuse inserts are accessible to laypersons and can be replaced by them. It is the most modern screw-type fuse system and is designed for 400VAC/250VDC. The sizes D01, D02 and D03 make up the D0 system. D0 fuse bases are used together with D0 fuse inserts to protect cables and systems. D0 fuse inserts safely switch off impermissible overcurrents and short-circuit currents up to the nominal breaking current. They also protect electrical devices and systems from the electrodynamic effects of high short-circuit currents. DIN0636-3, DIN EN 60743. The sleeve inserts and the design of the fuses ensure that no larger fuses can be screwed in than are permitted for the cable.
