My common model IKEA stove – rebranded Siemens or Electrolux – runs at ~400v (Northern Europe). I know because it broke and I almost poked at it, until I got spooked by the warning labels. It's on its own circuit. Not an expert but as far as I know, most houses in Western/Northern Europe have a three-prong stove/oven connection in the kitchen for a ~400v feed.
