Is NETIO PowerPDU 4C a smart PDU or a smart socket device?

The distinction is not entirely clear-cut but in general, PDUs are intended for 19" racks.  Also, the IEC 60320 C13 /C14 connectors are typical for the IT world.

Products with the wall-type 230V sockets (Type F (Schuko), Type E, ..) are usually called „smart sockets“.
