Fuses with Contact Knives
We recommend two types of fuses with contact knives: fuses with slotted knives according to DIN 43653 and fuses with solid knives
according to DIN 43620. The former are mounted direct on busbars or in special fuse holders and the latter in spring-loaded fuse
bases.
Use the biggest possible bolts/studs, nuts, and washers (recommended) to tighten the DIN 43653 fuses to a torque of 50 Nm.
Tighten the DIN 43653 fuses in accordance with the specification provided with the base.
