Rated currents
Permissible design current for fuse link with nominal current In:
Nominal current fuse link
In >250 A ... 630 A
In >160 A ...250 A
In >32 A ...160 A
In ....32 A
Short-time load (up to 30 min), In
Rated currents of the device sizes= F x I
For total current of all branches at the section
