CEE 7/17

 

CEE 7/7 are earthed plugs that fit in CEE 7/3 (Schuko) as well as CEE 7/5 (French*) sockets, because plugs have both earth clips and a contact for sockets that have an earth pin.

CEE 7/7 plugs - rewirable or integrated with a cord - are often made by companies that sell products in many European countries, irrespective the local socket standard.
It is also a profitable strategy for production of special types that have a smaller market share than sales of plugs for domestic use.

CEE 7/17 plugs, the not earthed version of CEE 7/7, are shown on a separate page.

* CEE 7/5 sockets and 7/6 plugs are often designated as French type, but it is debatable whether 'French' is correct; see page about origin of earth pin sockets.
