IEC 60906-1

from Wikipedia, the free encyclopedia
IEC-60906-1 standard connector

IEC 60906-1 is an international standard for 230 V AC connectors .

The standard was published in 1986 by the International Electrotechnical Commission . With the SANS 164-2 standard, South Africa introduced this standard alongside the old standards. On January 1, 2010, Brazil made the mandatory NBR 14136 based on this standard.

The first part of the IEC standard describes the standards for plug connections up to 250 V and 16 A. The second part of the standard ( IEC 60906-2 ) published in 1992 defines the international standard for plug connections up to 125 V. This standard is the same as today in North America used plugs and sockets ( type A and type B ) compatible. Part 3 ( IEC 60906-3 ) describes a group of low-voltage plug connections.

Description of the plug and socket

The connector has three round, 19.5 mm long pins with a diameter of 4.5 mm. The centers of the two outer pins are 19 mm apart; the center of the protective conductor pin is 3 mm away from the center line. The two outer pins have metallic and rounded tips that sit on insulating plastic sleeves. The protective conductor pin is made entirely of metal with a rounded tip. The height of the connector front is 17 mm, the total width 35.5 mm.

The socket is located in a recess of 10 mm or has a 12 mm high rim to prevent touching the pins of the plug. The construction of the socket ensures that the protective conductor makes contact first when the plug is inserted ( protective connection leading up ). The socket and plug are protected against polarity reversal (if the PE is below, the L-conductor is in the socket on the left and the N-conductor on the right).

Advantages of the connector system

  • The plug and socket are just as compact as the SEV-1011 or the type L plugs, so they are significantly smaller than, for example, the CEE-7/6 or the Schuko system.
  • The plug and socket are protected against polarity reversal.
  • The protective contact connection is leading, i.e. H. the earthing contact pin receives contact first when the plug is inserted.
  • The insulating plastic sleeves around the feet of the neutral conductor and the pin for the phase make it difficult to touch live plug pins.
  • By countersinking the socket, touching the plug pins is prevented.
  • Due to the hexagonal shape, the countersinking of the socket and the three pins, the system offers a secure mechanical hold and high mechanical strength, also against twisting.
  • The three-pole protective plug cannot be plugged into an ungrounded socket, i. H. Operation without a protective contact is not possible.
  • The plug and socket are designed for high performance (up to 250 volts and 16 amps; at 230 volts, 16 amps correspond to an output of 3680 watts).
  • The socket can accept today's flat plug , which makes it easier to switch to the system.

The system thus combines all relevant safety and performance features. Today's plug systems, such as the German Schuko system (type F), the British plug system ( type G ) or the Swiss system ( SEV 1011 ) each offer only a few of these advantages.

Differences to the Swiss connector

The plug is similar to the SEV 1011 standard used in Switzerland , but is not compatible with it due to the following differences:

  • The pin or socket for grounding is 3 mm away from the center line instead of 5 mm (CH).
  • The pin diameter is 4.5 mm instead of 4 mm (CH), which means that Type 11 plugs fit into IEC 60906-1 sockets, but not IEC 60906-1 plugs into Swiss sockets.
  • In IEC 60906-1, the outer conductor is standardized on the left instead of on the right (CH).

Brazilian standard NBR 14136

The Brazilian standard NBR 14136 was developed on the basis of IEC 60906-1 and was gradually introduced (after several postponements) between 2007 and 2010. Compared to the requirements of IEC 60906, however, there are a number of differences:

  • The pin diameter is not 4.5 mm and the current rating is not 16 A. Instead there are two combinations: 4 mm for 10 A and 4.8 mm for 20 A. 20 A sockets also accept 10 A plugs ( but not vice versa). The 10 A plugs fit into IEC-60906-1 sockets, IEC-60906-1 plugs into the Brazilian 20 A sockets.
  • Non-insulated pins are also allowed for phase and neutral conductors.
  • For class 2 devices, there are two-pole connector versions with a thickness of only 4 mm, i.e. almost the same contour as the Euro connector . This carries the risk that 10 A plugs are plugged into Euro extension cables (designed for 2.5 A) and can overload them (in Switzerland this is countered by the fact that the import of such extension cables is prohibited).

Furthermore, Brazil has had its own connector standard since 2004 (NM 60884-1 30/09/2004 Plugues e tomadas para uso doméstico e análogo), which is based on IEC 60884-1 (Plugs and socket-outlets for household and similar purposes - Part 1: General requirements).
