The CEE&nbsp;7/3 socket and CEE 7/4 plug are commonly called ''[[Schuko]]'', an abbreviation for ''Schutzkontakt'', ''Protective contact'' to earth ("Schuko" itself is a registered [[trademark]] of a [[Registered association (Germany)|German association]] established to own the term). The socket has a circular recess with two round holes and two earthing clips that engage before live pin contact is made. The pins are {{convert|4.8|by|19|mm|in|3|abbr=on}}. The Schuko system is unpolarised, allowing live and neutral to be reversed. The socket accepts Europlugs and CEE&nbsp;7/17 plugs and also includes CEE&nbsp;7/7. It is rated at 16&nbsp;A. The current German standards are [[Deutsches Institut für Normung|DIN]]&nbsp;49441 and DIN&nbsp;49440. The standard is used in Germany and several other European countries and on other continents. Some countries require child-proof socket shutters; the DIN&nbsp;49440 standard does not have this requirement.

The plug is used in most or many countries of Europe, Asia, and Africa, as well as in the countries of [[South Korea]], [[Peru]], [[Chile]] and Uruguay.{{Citation needed|date=August 2019}} The few European countries not using it at all are [[Belgium]], [[Czech Republic]], [[Cyprus]], [[Ireland]], [[Liechtenstein]], [[Switzerland]], and the [[UK]], or not using it predominantly are [[Denmark]], [[Faroe Island]], [[France]], [[Italy]], [[Monaco]], [[San Marino]], [[Slovakia]].
