I don't know if I got it right, if not, please redirect my inquiry. Well, I have old fuses in my apartment, the so-called 10 A and 16 A automats, I would like to replace them with the so-called S, what model should I use? , only one, outside C 20, I have to understand that the one installed by the electrician is a single-phase fuse, can it be changed accordingly?
