Two different types of 25A, 250V plugs and sockets can be found in Spain. The Schuko lookalike model is going to be phased out, but can still be found in workshops. The newer model has three flat pins.
Image nos. 8 - 22 show examples of obsolete single- and three-phase plugs and sockets.

1 Old model of a Spanish 25A, 250V single phase socket. It resembles a 16A Schuko socket, but it is about 13% larger.   {FSE}
2 Current model of a 25A, 250V single phase socket.   {FSE}
Spanish 25A plug that fits in the old model socket (no. 1).   {FSE}
4 16A Schuko plug (CEE 7/7 model) and Spanish 25A plug. Pin spacing is 19 mm (16A) versus 25.5 mm (25A). Pin lengths is respectively 19.2 and 23.7 mm, but both plugs have the same pin diameter (4.8 mm).
5, 6 Current type 25A plug. Note that the earth pin is 2.7 mm longer than the power pins; consequemtly, earth contact is made first when equipment is plugged in. The plug is polarized (does not fit upside down in a socket) because of the shape of the housing, but neighter plug nor socket has any indication of live and neutral. The 'polarity' seems only be meant to ensure a correct earth pin contact. See also plug no. 7, shown below.   {FSE}
7 Norwegian 25A-250V cooker plug, essentially identical to Spanish plug no 6. Specification given by the Norwegian manufacturer ELKO indicates the correct wiring. It is not known whether Spain has adopted the Norwegian 25A plug, or vice versa.

8 Plate with three different types of Eunea type Metropoli outlets. Each is rated at 16A - 220-380V. Corresponding plugs are shown in image nos. 9, 10 and 11. Manufacturers: Eunea* (plate) and BJC* (outlets).
9 Eunea Metropoli not earthed, 2 pole socket, rated at 16A - 380V. Dimensions of the flat blade power pins are 10 mm wide, 2.0 mm thick and 18 mm long; blade spacing is 30 mm. Although the plug is clearly polarized, line and neutral are not specified.
Manufacturer: BJC.
10 Eunea Metropoli earthed, 2 pole socket, rated at 16A - 380V. The round earth pin has a diameter of 4.5 mm and is 19 mm long. Although the plug is clearly polarized, line and neutral are not specified. Manufacturer: BJC.
11 Eunea three-phase plug, rated at 16A - 380V. Manufacturer: Eunea.

Metropoli devices are no longer in production, but Eunea Metropoli sockets and plugs can still be found in Spain. Some material is available for repair (2017).

BJC stands for Fábrica Electrotécnica Josa, in Rubí near Barcelona. The company has been founded in 1926. In 2008 it became a part of the Siemens Building Technologies Division (Zug, Switzerland). Besides BJC also the trademark JOSA has been used.

Eunea was founded in 1972 as a division of B.J.C. Four years later it became and independent company that focused on domestic electrical material. In 1992 Eunea merged with  Schneider Electric España. A new plant was build in Puente la Reina, Navarro.

Three-phase plugs, connectors and sockets nos. 12-19 have a rubber casing. They have been made by Industrias Jangar, a still existing company based in Zaragoza, Spain.
12, 13
Three-phase plug and socket, rated at 15A - 250V (plug), 380V (socket). Pins have a diameter of 5.0 mm. They form an equilateral triangle with 20.5 mm pin spacings. Similar 15A, 3-phase, 3-pin material has been made in France (Legrand) and Italy (VETO), but pin spacing is a bit different for each of the models, which makes them hardly compatible.   {FSE}
14, 15
Plug and connector comparable to nos. 12-13, but with a centrally positioned neutral pin (5.0 mm diameter). Connector plug is rated at 15A - 250V, rather than 380V for socket no. 13.   {FSE}
16, 17 Three-phase plug and socket, rated at 30A - 380V. Pins have a diameter of 8.0 mm. They form an equilateral triangle with 24.6 mm pin spacings.   {FSE}
18, 19 Plug and connector comparable to nos. 16-17, but with a centrally positioned neutral pin (5.5 mm diameter).   {FSE}

Shield with C logo of Spanish company
Sockets and plugs shown in image nos 20 - 25 have been made by an unknown Spanish company that used a shield with a C logo. None of these devices have an indication of rating. Given ratings are based on pin size, pin spacing and comparison with material made by Industrias Jangar, shown above.
20 Three-phase socket with centrally positioned contact for neutral pin. Estimated rating: 20A - 380V. Power contacts form an equilateral triangle with 35mm spacings (centre to centre). Power contacts are meant for 5 mm pin; neutral contact for a 4 mm pin. Plug no. 14 does not fit because of different pin spacing and the neutral pin has a larger diameter.   {JRC}
21, 22
Large three-phase socket and matching plug. Power pin spacing is 39 mm. Diameter of power pins is 8 mm and 6 mm for neutral pin. Length of each of the pins is 30 mm. Neutral pin makes contact first with the advanced position of the central socket contact. Estimated rating: 25-30A - 380V.   {JRC}
23 Two pin plug. Pin diameter: 8 mm, pin length: 30 mm, pin spacing: 27.4 mm. Estimated rating: 25-30A - 380V.   {JRC}
24, 25
Connector for a 3-pin plug with 8 mm diameter and max. 30 mm long pins. Estimated rating: 30A - 380V.
Image no. 25 shows that the connector consists of three parts. Left part: massive rubber block with three 30 mm long holes for brass contact tubes. The block has on both sides flexible rubber sleeves. One that wraps around the other parts of the connector, the other protrudes and can be wrapped around a matching rubber plug.
Middle part: round steatite plate with three brass contact pins and at the other side nuts to fix wires. Right part: flexible rubber casing that encloses the steatite plate (plug nos 22 and 23 show a similar construction).
The Industrias Jangar connector nos 15 and 19 have a comparable system to achieve a closely sealed connection between male and female plug.   {JRC}
