What is recommended Fuse protection for DC coupled Variable frequency drives Altivar ATV71?
Rating of the fuses is shown in attached file. All fuses are fast-acting fuses (also called high speed fuses, semiconductor fuses, etc.)
These fuses are dedicated for both DC and AC. In the picture you will find out that rated voltage for the fuses depends on ATV AC supply voltage. For ATV...N4 drive supplied by 400V you need fuses that are rated 690V AC at more.
Search fuses from one of global suppliers, like Ferraz, Bussmann, Siba,
For example when searching 160A fuses for ATV71HD30N4, by looking at

page 99, one example is fuse 170M3014 (160A, 690V, high speed square-body fuse) or its variant (with indicator, microswitch, etc.)
another body style is fuse 170M1319 (page 93)
