ᐅ Old Building Unknown Outlet – High Voltage Socket for Oven?

Hello,
please excuse me. This is my first forum post. If I’m doing something wrong, please correct me.
I bought an older house built in 1961. In my kitchen, there is an outlet with three slots in a crescent shape. Two crescents face inward, and the middle one faces outward. What is this? Is it a high-voltage connection for a stove? There is already a cable coming out of the wall where the stove was in the kitchen...
Thank you very much

Hello,

I think you would have more success here with a photo. 😉

Thank you for the tip. This is what it looks like.

This is Terko.
It was used for special networks. There could be anything hidden behind it.

Just measure what is connected. For three-phase power, this is not enough poles...

As Alex says Terko.

• Plug system: 2P+E, reverse-polarity proof, plug can only be inserted in one position.
• Voltage: 250 V
• Current: 16 A
• For special networks according to VDE 0100 G 7.76 § 31a 2.1, can be used to ensure unambiguous identification.
