I noticed no one is answering this. From what I can tell, you have the option of either using a V rating of "380/460 VAC" and an RPM rating of "2850/3600 RPM" as a catch-all system, OR using all of the built in "RATING" attributes, 1 through 4, with 2 of them being used for the 380V case and 2 being used for the 460V case. Then after you place the symbol and select the cat number, just hide the two rating attributes that don't apply.
