Hi Guys, I was finish with my load calculation, and now my problem is what fuse to use. As i surf the net there are lots of Fuse to be found in the market. Although my calculation is base only in theoretical basis, so my question is when to use this following fuse. 1.) Controlled vented power fuse 2.) expulsion fuse unit 3.) Nonvented power fuse 4.) power fuse unit 5.)vented power fuse i was lost as for theory the use of FUSE is for over-current protection.
