Semiconductor type F1 fuses and fuse holders for AC and DC power lines
(DCS800-S01 / DCS800-S02)
The converter units are subdivided into two groups:
• Unit sizes D1, D2, D3 and D4 with rated currents up to 1000 A require external
fuses.
• In unit sizes D5, D6 and D7 with rated currents of 900 A to 5200 A, the branch
semiconductor fuses are installed internally (no additional external semiconductor
fuses are needed).
The third column of the table below assigns the AC fuse type to the converter type.
In case the converter should be equipped with DC fuses according to the hints, use
the same type of fuse as on AC side at DC side (C1, D1). Blade type fuses are used
for all the converters construction type D1...D4 except the converters
(610 A, 680 A, 740 A, 820 A, 900 A, 1000 A).
Fuses and fuse holders (details see chapter Technical Data)
Note 1: No fuse holder is available. Attach fuses directly to busbar.
Fuses F3.x and fuse holders for field supply
Depending on the protection strategy different types of fuses are to be used. The
fuses are sized according to the nominal current of the field supply device. If the field
supply unit is connected to two phases of the network, two fuses should be used; in
case the unit is connected to one phase and neutral only one fuse at the phase can
be used. Table below lists the fuse currents with respect to the table above.
The fuses can be sized according to the maximum field current. In this case take the
fuse, which fits to the rated field current levels.
