The IEC 309 HP system comprises plugs and socket-outlets from 16 to 125A in two different
versions – straight mobile and 10° flush-mounting – available in protected versions with IP44/IP54
degree of protection and watertight versions with IP degree of protection of up to IP66/IP67/IP68/IP69
(the first and only on the electro-technical scene to have this). The introduction of all the clock
references for the earthing contact completes the range for specific applications and installations.
The 16-32A versions require screw or quick spring wiring, while the 63-125 A versions employ branch
ing terminal connection technology.
