Fun fact
The position of the keyway (like a clock hand) encodes the voltage too, so a 230 V plug physically cannot enter a 400 V socket.
Tips & tricks
The blue 16 A version is also what most caravan hook-ups and portable EV chargers use.
Philosophy
Power for places where things get wet and kicked. Colour-coded so even a tired electrician cannot get it wrong.
