Fuses fuses fuses

Ok, this is about fuses

1- a standard Bussman fuse is UL approved. Are any "high end" fuses UL approved?

2- do any component manufacturers supply their gear with any of the usual suspects of high end fuses as opposed to a standard Bussman?

3- let's say fuses do make a difference. Given incoming power is AC, why could fuses be directional? 

Not meaning to light any fires here- 

thanks in advance

It should be pretty obvious that you would want the direction exhibiting the lower resistance.

You may think that its pretty obvious, but in cable manufacturing that isn't the case.... Impedance, DC resistance, inductance, capacitance, skin effect all come into the effect of a cable....
Of course here we are speaking of a simple wire, maybe I shouldn't assume that a tasty gourmet fuse would have more than simple DC resistance as a parameter.
