IEC 60309 connectors are keyed so that a plug cannot enter a socket carrying a voltage its equipment cannot take, and the keying is done by colour together with the clock position of the earth contact. Colour alone is not the whole code: blue is the 200 to 250 volt band and red the 380 to 480 volt band, but within a band the earth position also encodes the frequency and the exact voltage, which is precisely where a 60 Hz country importing 50 Hz-market equipment runs into trouble. A red 32 amp plug from a European supplier can be mechanically wrong for a red 32 amp socket bought for a 60 Hz system, and the discovery happens on site. So state the voltage, the frequency, the current and the number of poles together, and say whether you need interlocked units — where the socket cannot be switched on until the plug is home, which is the norm for anything above a few kilowatts.
The more of this you send, the closer the first quotation lands.
| Voltage and frequency | Both together — the earth position encodes them |
|---|---|
| Current rating | 16, 32, 63 or 125 amperes |
| Poles and earth | 2P+E, 3P+E or 3P+N+E |
| Colour code | Blue 200-250 V, red 380-480 V, yellow 100-130 V |
| Interlocked or straight | Mechanically interlocked switched socket, or plain socket |
| IP rating | IP44 for splash, IP67 for washdown or temporary outdoor use |
| Mounting | Surface, panel, angled, or a wall-mounted combination unit |
| Combination unit | Socket plus breaker and RCD in one enclosure |
| Matching plugs and couplers | Order the mating parts with the sockets |
| Cable entry | Gland size for the trailing cable used |
