There are many of these here (Greece, Crete, Iraklion Prefecture) at first I thought they were circuit breakers, but then saw one of them wired in delta, and that's defintely not a way to wire a circuit breaker!and of course circuit breakers don't need potential transformers, they need current transformers! I will post a link to a photo as long as I can take a photo of one of them! (they're only at rural areas!)
