run fuses in parrallel?
(OP)
I did some study regarding the possibility of using fuse -contactor scheme for 10kV motor. I have noticed that there are no large rating fuses which can suit large motor application. The max. 12kV fuse for motor protection is rated 200A. Apparently it is not good for some larger motors as shown in the TCC. The manufacturer recomend that I use fuses in parallel to increase fuse ampacity.
I am not sure it is appropriate or not? What is the disvantage of doing so?
Thank you in advance.

As per NEC, fuses connected in parallel should be factory assembled and listed as a unit. That means, this kind of products are called 2 barrel or 3 barrels per phase and should be listed in their catlogue?
Is my understanding correct?
Thanks.
