My latest novels are all in the 110k word range, and they are each one part. I have read plenty in the 200k range that are in one part.
What genre are they in? If its Sci-fi or Fantasy, those readers tend to expect longer books. 150k divided in three gives you 50k a book... and they will see that as too short. 150k is not really all that long for sci-fi fantasy. If its Romance, those tend to run shorter so I would suggest breaking it in at least 2 of not three parts.
Other genres have their own expected length. Poke around your genre and see what they are running.
