Semiconductor type fuses and fuse holders for and power lines
(DCS800-S01 DCS800-S02)
The converter units are subdivided into two groups:
• Unit sizes D1, D2, and with rated currents up
to 1000 require external line fuses. Blade type fuses are used
for all the converters construction type D1. Fig. 2

.
The table assigns the fuse types the converter
types.
• unit sizes D5, and with rated currents
of 900 5200 the semiconductor fuses are
installed internally (no additional external semicon
ductor fuses are needed)
