- IEC 60309
IEC 309 (now IEC 60309,
1999 ) is aninternational standard from theInternational Electrotechnical Commission for "plugs, socket-outlets and couplers for industrial purposes". Part 1 of the standard specifies general functional and safety requirements for any form of industrial high-current power connector. Part 2 specifies a range of mainspower connector s with circular housings, and different numbers and arrangements of pins for different applications. The highestvoltage allowed in the standard is 690 V DC or AC; the highest current, 250 A; and the highestfrequency , 500 Hz. The temperature range is −25 °C to +40 °C.In the
United Kingdom , this standard was first adopted asBS 4343 :1968 and has since been replaced by its European equivalent EN 60309:1999, catalogued in the BSI system as BS EN 60309:1999.Keying
IEC 60309-2 connectors are produced in many variants, designed so that a plug of one type can only be inserted into a socket of the same type. Different current ratings (such as 16 A, 32 A and 63 A) are distinguished by different diameters of the circular housing.
Different voltage and frequency combinations are distinguished by the location of the ground pin (or a plastic projection called the "minor keyway", for connectors with no ground pin), as shown in the following table. The ground pin can be in one of twelve locations spaced at 30° intervals around the circle on which all the pins lie. Position 6 is at the same angle as the "major keyway", a projection on the plug casing that aligns with a notch on the socket. The ground pin has a larger diameter than the other pins, preventing the wrong type of plug being inserted in a socket.
A six-phase plus earth (6P+E) version also exists.
