The fuses I ordered were supposed to be Slow Blow MTC Series but every one appears to have a Fast Blow element inside the glass. Every fuse, regardless if amp rating has a "F" preceeding the fuse amperage and no indication that the fuse is a Slow Blow as advertised. If all fuses ordered are Slow Blow, I need documentation that supports this claim because they do not have the delay element inside the fuse that creates the "Slow Blow" feature. The accompanying photos show the varaious amperage fuses I ordered and a closeup view of one end of a 10 amp fuse that clearly shows F10V and no other indicator that the fuse is Slow Blow. If a mistake was made I need a replacement order sent as soon as possible. I await an explaination from the vendor concerning this apparent error Vendor needs to label the fuse boxes as either Fast Blow or Slow Blow. Currently, no labeling of fuse type appears on fuse boxes.
