Are Semiconductor fuses polarized?

[allentrop]

Are Semiconductor fuses polarized? I know it may be a stupid question but I recently purchased Bussman semiconductor fuses for a drive that we are having problems with. I notice the diagram on the side of the fuse that looks like a resistor and diode. Nothing else on the fuse indicates any kind of polarity, but i though i would just ask anyway.

Thanks!

There is no such thing as a polarized fuse. In my years, I've never seen or heard of a polarized fuse, so any diagram or illustration of components on the side of the fuse is most likely there to indicate that it protects components. If anyone can find a polarized fuse, please post a picture here.
