They are also sometimes used in situations where their special capabilities (such as high current rating or three-phase facilities) are not needed, to discourage potential users from connecting domestic appliances to the sockets, as 'normal' domestic plugs will not fit. The fittings are popular in open-air conditions, as the connectors have a minimum IP44 weather-proofing rating. Connectors generally are specified by the voltage and current ratings, general configuration (number of pins), and rotational alignment ("keying"). There is a range of plugs and sockets of different sizes with differing numbers of pins, depending on the current supplied and number of phases accommodated. The ambient temperature range is −25 ☌ to 40 ☌. The maximum voltage allowed by the standard is 1000 V DC or AC the maximum current, 800 A and the maximum frequency, 500 Hz. They are also used in the entertainment industry where they are commonly referred to as "CeeForm" connectors.

IEC 60309 (formerly IEC 309 and CEE 17, also published by CENELEC as EN 60309) is a series of international standards from the International Electrotechnical Commission (IEC) for "plugs, socket-outlets and couplers for industrial purposes". (optional) last-make, first-break to control arcing When mated, the spring-loaded cover on the socket hooks over the lug visible on top of the plug to lock the two together.Ģ00–250 VAC (blue) 16/20 A 2P+E 6h socket for single-phase AC power. The female socket has two additional divots which are not required by the standard, but provide access to screws to disassemble the socket. The round plug shroud has an alignment key that mates with a matching slot in the socket.
