Perilex is a plug-in system for three-phase current connections and is less well known than the classic CEE plug-in system. It is used in particular in small businesses such as carpenters' shops, butcher's shops and bakeries, in laboratories and hospitals and occasionally in private households. This system is not used in industry and construction because it is not approved for outdoor use and the alternative CEE connector system is significantly more robust. The CEE connector system can be easily recognized by the colored plugs, sockets and couplings, of which the red and blue variants are the most common. The blue single-phase variants are the 230 volt / 16 ampere connections for camping and caravanning, the red three-phase variants are differentiated into 400 volt / 16 ampere or 400 volt / 32 ampere connections depending on the design. For the private and industrial sector, there are other, quite rare CEE connectors in a wide variety of colors, some with special properties, other diameters and additional contacts for multifunctional applications. You can obtain plugs, couplings and sockets for the most common CEE and Perilex connections from the eibabo technology store.
