No fuse holder is available; attach the fuses directly to the busbar.
Fuses and fuse holders for armature circuit (details see chapter
Fuses (F3.x) and fuse holders for field circuit
Depending on the protection strategy different types of fuses are used. 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. If the field converter is connected to two phases of a 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. The
table below lists the fuse currents depending on the table above.
Fuse (F3.1) KTK25 included in FEX-425-Int package. H5 field fuses are external. H6 field fuses are internal.
