Hello Guys,

What does the following mean?

3W+N+PE 220/380 V, 230/400 V, 240/415 V, 50/60 Hz, 3 x 16 A
3W+PE 220 V, 210 V, 220 V, 230 V, 240 V, 50/60 Hz, 3 x 25 A


thanks and regards

Pl. mention the source at the place these ratings were printed.
 

Re: One basic question

Probably is the characteristics of the socket for mains connection:
- 3W = 3 wire connection ( tri-phase system )
N = neutral wire

PE = Protective earth ( ground )
220/380 - 230/400 - 240/415 V = viltages star-delta connection ( first star connection ) depending on the nominal voltage of the country where the system is installed

50/60 Hz = nominal frequency ( Europe = 50 Hz )

3* 16 A = Maximum current on each phase.
