Plug type help needed - IEC 309 60A 3P+PE

[BillP]

I am getting conflicting information about this connector: IEC 309 60A 3P PE

Some sources are telling me its a 4 wire and others are telling me its a 3 wire.    I am a rookie but I believe three phase plus earth is a 4 wire.

It is my understanding if it is a three wire it will require a 360R6W receptacle but if it is a four wire it will need a 460R6W receptacle.   

Can anyone help me out here?

How about a different approach.... does anyone have a picture of the AP6007A plug?  This is the PDU I'd like to position and I need to ensure it is compatible with the 360R6W.

Thanks in advance,

Jeff
