AS/NZS 3112

The plug - type I (Australian 2/3-pin ) is in Australia, New Zealand, Papua New Guinea, China, Argentina and Uruguay in use.

Generally

This connector, which is used in Australia, New Zealand and Papua New Guinea is, three-wire, has an earthing contact and is designed for a nominal current of 10 A. The grounding plug is a vertical flat contact. Neutral and phase are in the form of an inverted V above. They are each rotated by 30 ° against the grounded and have a nominal distance of 13.7 mm. Such outlets usually have a voltage of 230 V at 50 Hz since 2005, is a finger safe isolation of power contacts compulsory.

Dissemination

The following countries set to a type I counted connector systems:

  • Australia: the authoritative standard: AS / NZS 3112
  • New Zealand: the authoritative standard: AS / NZS 3112
  • Papua New Guinea: the authoritative standard: AS / NZS 3112
  • China ( in part): the authoritative standard: GB 1002
  • Argentina: the authoritative standard: IRAM 2073
  • Uruguay: authoritative standard: a standard IRAM 2073

Standardize

For the type - I connector, there are several standards that define a very similar connector systems. The most authoritative and oldest is the Australian standard AS 3112th

AS 3112 (Australia)

Originally 1937/1938 defined in Australia as standard C112, the standard has been superseded by the 1990 standard AS 3112. Since the dawn standard in Australia, New Zealand and Papua New Guinea today is the authoritative standard AS 3112 for these countries. The standard defines a polarized plug, in which the phase ( active) on the socket based on the left. Law is neutral and in the middle below the earth. The contacts are flat, rounded at the ends of metal pins with the dimensions 6.5 mm × 1.6 mm. The power contacts are 18 mm in length and angle of 30 ° are in an A-shaped with respect to the protective conductor and have a nominal distance of 13.7 mm. The protective conductor is 20 mm longer and thus require haste. When plugging the earth contact is made before the power and disconnect it last again when unplugging. Since 2003, the standard also includes finger safety, which is realized by a 9 -mm-wide isolation of the two current-carrying conductors. The ultimate and definitive standard from 2003 is AS / NZS 3112:2000. It prescribes the isolated contacts from 2005.

IRAM 2073 (Argentina )

In Argentina and Uruguay, a similar connector exists. The most important difference is that the neutral and live are reversed.

GB 1002 ( China)

In the People's Republic of China, there is a very similar to the Australian standard, mechanically but not identical standard. The most important difference is that the sockets are rotated 180 °. The ( always existing ) grounding is so above and not below. There is no insulation of the conductors present. There is also a, mainly for the installation of air conditioning provided and mounted at head height 16 amp version, in which all contacts thicker, longer and higher. The specified rated voltage in the PRC is 220 V 7 % / -10 %.

Parallel 1002 still defines the connector type A or NEMA 1 (for without a ground wire to 10A applications) in the UK. Modern outlets can also take on the Euro Plug Type C CEE 7/16.

Variants

In addition to the 10 A version there is also a version that is certified for a rated current of 15 A. She has a slightly thicker, longer and higher earthing contact. These sockets are backward compatible with the 10 -A plugs. In addition there exists a 20 amp version, in which all contacts thicker, longer and higher, a 25 - and 32 -A variant in which the pins are as enlarged as in the 20 A version. The ground wire is in the 25 A variant in the form of a mirrored L, in the 32- A- variant, it has the shape of a square U. All sockets are backwards compatible. So take each plug smaller rated current on, but not vice versa.

For double insulated Class II devices, there is a two-pin variant of the 10-amp plug. It fits into any socket variants, but offers protection for lack of a worse contact support. He is usually to be found where in Europe the euro plug would be used.

More

The Australian Standard AS 3112 also specifies multiple plugs in various designs as well as plugs for self-assembly.
