And perhaps like the Furman device too, I don't know if there's a 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.
