Can I use a 65 A rated fuse link in a 200 A rated fuse holder?

No. 200 A rated fuse holders are only to use fuse links rated between 101 A and 200 A. The 100 A rated fuse holders are only to accept fuse links between 1 A and 100 A. This is because the inner diameter of the fuse holder is critical to the interruption of fault current. The 200 A fuse holder diameter is too large for use with fuse links less than 100 A and would not interrupt system faults properly.
