Schuko can have a fuse as safety feature (Schutzkontaktstecker mit Gerätesicherung), but you have to set the fuse below the fuse that’d be behind the socket (which means your fuse would be below 8A if you want to be safe, though because 16A fuses are more common, so a common fuse to actually be installed is 10A).

In most cases, the fuse is just in the device itself rather than the cable. Ideally then that fuse is also replaced easily.
