Where I work, we use vacuum starters for all NEMA size 4 and 5 starters. We also have a general guideline where anything above 200hp is medium voltage (2300V.)
Starters in general will arc and pit when opening/closing, not much you can do about it. The vacuum starters will keep the splatter...
I had a sales person from Littelfuse in a couple of weeks ago and he indicated they may make something similar to what you are looking for. The Model # from the manual indicates either the PGM-8134 or PGM-8125.
Hope this helps
