Connector type 12 SEV 1011
SEV 1011 socket type 13

The SN 441011 , until 2019 SEV 1011 , is a Swiss standard for plugs and sockets for domestic use.

  • The single-phase system is standardized for 250 V AC at 50 Hz and, depending on the type, is dimensioned for currents up to 10 A or 16 A. For devices with nominal peak values ​​of 16 A, there are plugs type 21 and type 23 as well as the socket type 23 with rectangular pins.
  • The three-phase system is standardized for 250 V / 440 V AC voltage and dimensioned for currents of either 10 A ( SEV 1011: 2009 type 15 ) or 16 A ( SEV 1011: 2009 type 25 ); the sockets (type 15 and type 25) are not only compatible with the three-phase plugs of the same type, but also with the plugs type 12 and type 13 (or type 23 for the socket type 25).

In the versions with three contact pins (types 12, 13 and 23), the middle, slightly offset pole is the protective contact . Although the contact pins are of the same length, the protective contact is in advance because the sockets for the neutral conductor and outer conductor are sunk deeper in the socket. The offset arrangement of the contacts ensures reverse polarity protection (with a socket, the outer conductor is on the right and the protective conductor is at the bottom). The sockets are equipped with protective collars. Sockets without protective collars were allowed outside of wet rooms until 2016, but existing sockets of this type can continue to be operated.

The system is “hierarchically downward compatible” for multi-phase / single-phase devices with possibly low (standardized) current peaks (10 A or 2.5 A for the Euro plug ).

Dimensions

The SEV 1011: 2009 standard: The hierarchically compatible Swiss system of power plugs and sockets for the household sector
Dimensions of the protective collar for sockets
Collars of sockets according to T11 and T21 are at least 16 mm (+1 mm) wide, those according to T13 and T23 at least 21 mm (+2 mm) wide. All collars of these types are at least 36.5 mm long. The respective angles are 45 degrees. Those of three-phase sockets have a dimension of 37.2 (± 0.7) × 39.5 (± 1) mm.
Protective collar depth for sockets
With single-phase sockets (T11, T13, T21, T23) the protective collar is 13 mm (+5 mm), with three-phase sockets 17.5 mm (+1 mm) deep.
Dimensions of the connector
Plugs according to T11 and T21 are between 13 mm and 14.5 mm wide, those according to T13 and T23 between 14.5 mm and 20 mm wide. Connector according to T1 and T13 between 35 mm and 36 mm long. The respective angles are 45 degrees. Three-phase plugs have a dimension of 35.4 (± 0.7) × 30 (± 0.7) mm.
Pin length of the connector
The pins are 19 mm (± 0.5 mm) long on all types. The length of the insulation on the connector pins is 8 mm (± 0.25 mm).
Diameter of the pins and the openings
The pins of the 10 A connector have a diameter of 4 mm (± 0.06 mm). The diameter of the openings in the sockets is 4.5 mm (+0.2 mm). The pins of the 16 A connector are 4 (± 0.06) x 5 (± 0.06) mm wide, the corresponding openings are 4.5 (+0.2) x 5.5 (+0.2) mm wide.
Distance between ladders
In both the 10 A and 16 A versions, the distance between the outer conductor and the neutral conductor is 19 mm (± 0.15 mm). The protective conductor is offset by 5 mm (± 0.1 mm). With the three-phase plugs and sockets (T15 and T25), L2 and L3 are offset by 8 mm (± 0.1 mm) from the protective conductor, i.e. H. the distance between L1 and L2 or between N and L3 is 13 mm.

properties

Swiss sockets: type 13 above and below, type 14 in the middle

The system is reverse polarity protected , the outer conductor is always on the right with 230 V sockets if the "triangle" with the protective conductor in the middle points downwards; this is the usual assembly for single sockets.

Type J SEV 1011 (plug without insulated contact pins, sales no longer allowed since 2013)
With sockets without protective collars (type 12, sales prohibited from 2017), dangerous voltage is freely accessible with T12 plugs according to the old standard (above), with plugs according to the new standard (below) this danger does not exist.

In the case of outdated sockets without protective collars (T12), live contact pins are freely accessible during insertion and removal, provided that older standard T11 or T12 plugs are used. There is a risk of an electrical accident there . For this reason, no such plugs (T11 and T12) without insulation may be brought into circulation since January 1, 2013, since 2017 no sockets without protective collars (T12) may be reinstalled.

The plug of type 12/13 with its permissible load capacity of 10 A can be inserted into a socket of type 23, which is usually fused with 16 A. This means that these plugs are not protected against overload in the range between 10 A and 16 A by the house installation. Such a load would be conceivable, for example, with a type 13 multiple socket to which several larger loads with type 13 plugs are connected. Therefore, type 13 cable drums must be provided with overload protection; socket strips without overcurrent protection were only allowed to be manufactured until the end of 2015 and sold until the end of 2018 according to SEV 1011: 2009 / A1: 2012 . However, this does not solve the problem with multiple socket strips and cable drums of older standards as well as with branch plugs for which overcurrent protection is still not provided.

Compared to the Schuko system, the American system and systems without protective contacts, the current Swiss system is still considered to be one of the most space-saving systems. A standard connection panel for 230 volts can accommodate up to three (sometimes four) connections. The international IEC-60906-1 system shows great similarities.

The protective conductor is leading. The standard enforces a construction for sockets that ensures that the protective conductor is connected first. This is done by defining that the sockets of the outer conductor and the neutral conductor must be at least 3 mm deeper than the protective conductor socket (SEV 6534-1: 2009 for type 13, SEV 5934-1: 2009 for type 23).

Due to the hexagonal shape, the countersinking of the socket and the three pins, the system offers a secure mechanical hold as well as high mechanical strength, even against twisting. On the other hand, with outdated sockets without protective collars, two-pin plugs do not always find a secure hold, so that they can be pulled out of the socket when the cable is pulled (for example, the resistance of the cable reeling in vacuum cleaners is often greater than the hold of the plug, which means that when vacuuming the plug can be pulled out of the socket). In the case of Euro plugs, the remedy is that the two pins are slightly curved towards each other, so the plug-in power supply units concerned can hardly fall out of the socket under their own weight.

The modular plug system allows the use of the plugs in sockets for higher currents as follows:

  • Type 12: three-pin plug / socket without protective collar, 10 A.
    • Socket accepts type 12 plugs as well as the two-pin Euro plugs and the old two-pin "square" or angled round plugs. Can also accept the three-pin connector of the old type 2, but the protective conductor function is then not guaranteed.
    • This type was only allowed to be sold until December 31, 2016.
  • Type 13: three-pin plug / socket with protective collar, 10 A.
  • Type 14: three-pin plugs / sockets with protective collar, 10 A. Double earthing both as a hole for type 12/13 and above for the old type 2 plug (similar to the French system CEE 7/5 , but not compatible with this, as the distance to the protective conductor does not match). Transition socket during the changeover to today's standard. May not be rebuilt since 1974, but can still be found on multiple sockets .
  • Type 15: five-pole plugs / sockets (400 volts three-phase current), 10 amperes (always with protective collar)
    • Socket also accepts plugs of type 12 and 13 as well as Euro plugs
  • Type 23: three-pin plug / socket 16 A, the plug pins are square (always with protective collar)
    • Socket also accepts plugs of type 12, 13 and Euro plugs
  • Type 25: five-pole plug / socket (400 volts three-phase current) 16 A, the plug pins are square (always with protective collar)
    • Socket also accepts plugs of type 12, 13, 15, 23 and the euro plug

compatibility

The sockets can accept the two- pin Euro plugs, but not the German contour plugs .

The GOST 7396 plugs , which are similar to the Schuko system, and some 2P + T plugs ( plug type E ) with thinner contact pins also fit in the sockets without protective collar, which are no longer sold . In these cases, however, the protective conductor function is no longer given, so that this use is life-threatening and fire-threatening . An adapter plug must therefore be used in this case.

The installation of other socket systems such as Schuko is not permitted in Switzerland.

Distribution, Similar Systems

The T-plugs are used in Switzerland and Liechtenstein. Despite the visual similarity, the connector type is not identical and not compatible with the connector type IEC 60906-1 based on the international standard . In literature or on the Internet it is sometimes mentioned that this type should also be widespread in Rwanda, Jordan or other countries, but this has not been proven.

validation

Until 1994, according to the house installation regulations (HV) at the time, a double over-protection of the J and T-type sockets was permitted. It was allowed to fuse a socket J15 with 25 A or T15 with 20 A. Since the introduction of the NIN in 1995, such overcollateralisation is no longer permitted, but the protection of existing assets remains guaranteed. Today it is forbidden to over-fuse a socket, with the exception that sockets with a rated current of 10 A (T13 or T23) can be fused with 13 A, provided that circuit breakers are used.

standard

The Swiss standard is described in the standard SN 441011 "Plugs and sockets for household use and similar purposes", which contains the following standard sheets:

  • SN 441011-1: Description of the systems with risk analysis and national deviations from the IEC-60884 series
  • SN 441011-2-1: Standard sheets and design specifications for plug-in devices with degrees of protection IP20 and IP55
  • SN 441011-2-2: Multiple and intermediate adapters, extension cables, socket strips as well as travel and fixed adapters
  • SN 441011-2-3: teaching

Products according to the outdated standard SEV 1011: 2009 may only be manufactured or imported until February 28, 2022.

Until 2019, SEV 1011: 2009 (ASE1011 / 1959 SW10A-R) was the relevant standard.

On December 4, 2009, the technical committee TK23 published the new, revised edition of the then standard SEV 1011: 2009 for 10 A plugs and sockets of type 11/12 in order to offer, among other things, improved protection against contact with partially insulated connector pins can.

From January 1, 2013, the import of type 11 and type 12 plugs into Switzerland will only be permitted with partially insulated pins. After 2016, only type 13 sockets with a recessed socket hole may be brought onto the market.

Other plug devices in Switzerland

Industrial connectors («J»)

Industrial plugs and sockets, so-called "J-plugs" and "J-sockets", were used in industry and agriculture for three-phase connections. While the grandfathering, which includes repairs or assembly, is in effect today, since July 1, 2008, no new devices may be sold. They were replaced by the CEE connector.

Industrial plugs are available in different versions for different nominal currents, such as J15-4 (15 amps, 4 poles; without neutral conductor) or J75-5 (75 amps, 5 poles; with neutral conductor):

J designation SEV type Rated current connections
J15-4 Type 30 15 A L1, L2, L3, PE
J15-5 Type 34 15 A L1, L2, L3, N, PE
