Euro plug
The Euro plug (EN 50075, also known as plug type C, "CEE 7/16", 250V / 2.5A) was developed in order to be able to connect double- insulated devices of class II with low power to the low-voltage network throughout Europe . It can be used across Europe with the exception of the United Kingdom , Ireland , Cyprus and Malta . In order to achieve this goal, a protective conductor was dispensed with. It belongs to the type C plugs, but such sockets are no longer installed in Europe.
Own Euro plug wall sockets are usually only available in hotels in the bathrooms as galvanically separated shaver socket units according to DIN EN 61558-2-5, but there are also multiple distributors for Euro plugs. While these sockets are forbidden in Switzerland due to their mechanical compatibility with type 11 plugs ( SEV 1011: 2009 , 250V / 10A ), in Germany they usually have contour plugs on the connection side in order to cope with the current load. Ready-made Euro plug extensions or Euro plugs and couplings are also available for self-attachment to cables. The round pins have a diameter of 4 mm and are 19 mm apart.

The flat Euro plug fits into numerous sockets that are designed for 220–250 volts:
- Swiss and Italian sockets
- Schuko sockets (including Germany, Austria, Hungary)
- French and Danish sockets for protective contact
- newer Israeli sockets
- new Brazilian sockets and in sockets of the new standard IEC 60906-1
- Type D sockets , taking into careful not to 5mm grounded in the middle to use, but not for Type M .
The Euro plug can be used in China on sockets that can also accept plugs that are similar to the Australian ones.
Among other things, the Euro plug cannot be used
- on Australian sockets
- to British and Irish BS 1363 sockets (plugging in is possible by manipulating the earthing contact, but extremely dangerous due to different electrical systems in the respective countries)
- to flat sockets for 110 V systems , as used in North America or Japan. However, there are also combination sockets that can accept both flat plugs and Euro plugs without changing the voltage (sometimes found in hotels).
A detailed list can be found in the article Country overview Plug types, mains voltages and frequencies .
operation area
The Euro plug is generally molded directly onto a line H03VV-F or H05VV-F with 2 × 0.75 mm² or 2 × 0.5 mm² (only permissible up to a length of 2 m) and may in all versions with a maximum of 2, 5 amps are loaded. Typical areas of application for the Euro plug are double-insulated, low-power devices such as radios and lights. For a higher current-carrying capacity, the Schuko system uses the contour plug without protective contact, which cannot be used in Switzerland. A plug that is mechanically compatible with the Euro plug is specified there ( SEV 1011 type 11 plug, 250V / 10A; the type 21 plug designed for 16A are mechanically incompatible).
production
Usually the Euro plug is injection molded d. H. Manufactured on an injection molding machine by encasing the connection line and the contact pins with a plastic compound in a single process step. The plug body and the cable kink protection are formed here. Opening or repair is not possible and, according to the standard, not desired. In electrical retailers, and more rarely in hardware stores, there are also individual Euro plugs and couplings with screw or solder connections for self-connection, which, however, do not meet the standard. Their housings are usually pushed over the inner part and snap into place.
standardization
The Euro plug is defined by the European standard EN 50075. In Germany it is defined by DIN VDE 0620-101 and DIN 49464: 2001-06 as: “Flat, non-reconnectable two-pin plug, 2.5 A 250 V, with cable, for connecting class II devices for household and similar purposes " Are defined. The Swiss standard SEV 1011 : 2009 does not define the Euro plug, reference is made to SN EN 50075, stating that all sockets according to SEV 1011 must accept Euro plugs.
Note: There are screwable Euro plugs available in stores to replace a defective plug. These plugs do not comply with the EN 50075 standard or the VDE and do not have a test mark. The risk is too great that the ignorant will attach a mountable Euro plug to devices that require a current higher than 2.5 A (e.g. vacuum cleaner, hairdryer or drill). These Euro plug extension cables are also not compliant, as extension cables without a protective conductor are generally not permitted according to VDE guidelines. In addition, due to the low power requirement, the cables for Euro plugs have a small conductor cross-section and are often only approved for up to two meters.
The two contacts of the plug have a 9 mm long metallic and rounded tip. They sit on 10 mm long plastic sleeves that have a smaller diameter in order to avoid any influence on the contact between the contact tips. The inclined and partially insulated pins ensure sufficient contact even with different sockets. The connector profile specified in the sketch opposite must be adhered to up to a distance of 18 mm from the front panel. The load capacity is specified at 2.5 amps and 250 volts.
Euro plug and English standard
British sockets are additionally secured compared to continental European sockets:
- Fuse in the plug
- Socket switch
- Mechanical cover of the sockets
- Release of the sockets only for plugs with earthing contact
If devices are fully insulated, grounding is not required. The foldable connector takes this into account. The contact for the protective conductor is replaced by an unfoldable plastic pin. Its task is to release the cover for the live contacts. If improvised, a Euro plug would also fit into a British socket, but since these do not have a fuse in the plug, such a construction is not reliable.
Miscellaneous
In Russia , the Schuko plug is called the "Euro plug". The Euro plug is called a "flat plug" or like the Russian plug, namely "ordinary plug".
In the UK there are still BS 4573 plugs . This is similar to the euro plug, but is smaller and only has a pin spacing of 16.6 mm, in contrast to the euro plug with a spacing of 19 mm. In addition, there seems to be, at least unofficially, real Euro plugs, as these fit into the old 5-ampere socket with round pins. However, this has 5.1 mm holes, but the Euro plug only has 4 mm pins.
