There are two variants, a more common 16 A version and a rarely used 25 A version. The connectors are equipped with five pins for protective earth (PE), a neutral conductor (N) and three phase conductors (L1, L2, L3; formerly: R, S, T). As the German industrial standard VDE 0100 prescribed the phase sequence for all types of three-phase connectors in a way incompatible with the original Perilex pinout, the R and T connectors may have been swapped. The PE socket protrudes slightly in order to give PE "first mate, last break" characteristics. In order to distinguish the variants, the 16 A version has a horizontal PE pin, whereas it is vertical in the 25 A variant.
