At my company, we use assembly codes. This makes for a rather extensive database list, but it works. We select the desired fuse, and the correct fuse block is automatically added by using an assembly code. For three phase circuits, the fuse has a default QTY of 3 and a three pole fuse block. The footprint symbol is also a three pole device with one device tag. I know some folks like to have a tag for each fuse, and this methode doesn't allow for that.
It helps to standardize components when doing this, but if you are an OEM, it could be a real challenge because there are many MFG of fuses and many more MFG of fuse blocks.
Good Luck!
