DO series OMEGA FUSIBILI

DO SERIES - THE FUSES
DO fuse links are used as the most reliable protection of electroinstallation, control and signal circuits against overloads and short-circuit currents. The whole system DO offers a complete range of fuse links, standard ceramic and new plastic bases, fuse disconnectors and all necessary accessories. The range is dimensioned for rated voltages 400 V a.c./250 V d.c. The system DO is intended to be used in residential, business and similar buildings. When it is used in industrial plants, it is necessary to take into account the requirements of the standard VDE 0110 concerning the air insulation, creeping and mounting distances.
FUSE BASES
The fuse bases DO are designed to be assembled into distribution boxes in domestic and public buildings where the use of B-type insulation is permitted.
- Modular construction-module 9 mm.
- Smaller weight and height (66 mm) provide installation into the flush-mounting distribution boxes, the deepness of which is 80 mm only.
- By adding a gauge-piece key it’s possible to change the gauge rings under voltage.
- The possibility of simple change of base DO1 with DO2.
