ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades Where are this kind of fuses used?

I just got these two, and have no idea of where they should be used. If you need it you may get it.

Actually I got these too, but that must be for low voltage. (I have 15 (1 broken))

The first image are old style Belgian fuses for use on a distribution board in a home / office. They were common until the early 1980s.

While these are made to Belgian CEBEC standards, I know there was a similar looking French system. I'm not sure if they're identical but they look rather closely related.
