We use many non-fusible disco's at the quarry where I work. We use them as a disconnect between every motor and starter. All of our fuses are located with with the starters in one cabinet. Therefore we have seperate disconnects that we can lock out to work on that piece of equipment. It seems to work good.
It also makes it simple to reverse rotation on a motor ( 3 phase ) without exposing yourself to a great danger.
