Internal and external fuses
Each rectifier module is equipped with internal fast-acting fuses with the following val-
ues 16 A, 250 V. The response times of the external fuses must be longer than those of
the internal fuses. Otherwise, the external fuse would blow immediately and the equip-
ment rack would be de-energized.
Figure 5.1 shows the time-current curves (response times) of the internal fuses. The
response times of the external fuses must always be longer.
