This is similar to what I'm using now and I called 'supermarket' device,

difference.
IIUC houses that were build after the second world war should be
pre-protected, but houses that are older could be without any
pre-protection. The later a house was build, the better the
pre-protection and without pre-protection as far as I understand, those
devices are completely useless.
I don't have enough serious sources, the best seems to be the German
Wiki referring to DIN VDE.
'Perhaps' next week or so, I'll do some more research.
Thank you,

arrester is meant to prevent.
According to the spec. this connector can handle 90 000 Ampere ! :

Does anybody know if there's a way to protect
equipment against damages
by lightning when there are no pre-protections?
