Transfer select column values to seperate table

I am trying to copy the values of 3 columns for all 120 rows in TableA to 3 columns with matching column names in TableB. Is there a simple way to do this?

Example:

TableA Over 100 Rows
Model
Class
Subclass
+ more columns, I just need the 3 above

TableB Empty
Model
Class
Subclass

Any easy way to do this?
