We have had this black/copper tube with Russian inscriptions lying around our house for years. Anybody knows what it is?

Looks like a fuse. The thinner bits of the strip inside are the part that melt when the current gets too high.

I think it is an electrical cartrage fuse. If the current is too high, the metal stop inside will melt & break the circuit.

It says "Made in the USSR", "600W, 15-60A" and "ПР-2У4".
