Table 6-8. Fuse sizes for Vacon NX Liquid-Cooled (690V) frequency converters
*Data in Italic refer to drives with 12-pulse supply.
** SHT fuses can be assembled into DIN fuse base of the corresponding size
Fuse information
Max fuse ambient tempe50ºC.
Fuse sizes can differ in the same chassis. Fuses can be chosen according to the biggest current rating of the chassis
to minimize fuse variants.
Check the current rating of the fuse bases according to the input current of the drive.
The physical size of the fuse is chosen on the basis of the fuse current: Current < 400 amps (size 2 fuse or smaller),
current < 400 amps (size 3 fuse)
