Reactor Start

DoE.

Since you are forcing us to fill in missing details, I'll take a guess that you are asking about a Reduced Voltage Reactor Starter for an AC induction motor. If so, almost nobody makes them as a standard catalog product any longer, because Reduced Voltage Solid State starters are the same or less cost and far more flexible to adapt to different starting conditions. However, it should not be terribly difficult to find a custom panel builder to make one for you. In the absence of any other information as to your whereabouts, I suggest starting with larger global sources such as Siemens, ABB or Schneider.They may not make them any more, but most likely can direct you to a nearby resource that will.

If this was not for starting an AC induction motor, I have wasted my time on you...

Troll!

Supply them with a light switch. Make sure the label says: Reactor Start!

Done! Dollar Fifty!

I did not think you can be OT with an answer to this question!

Which forums do you ask for investment advice?

Perhaps you should stick to importing copper and stay away from whatever reactor you may mean (be they chemical, process, beverage, nuclear, or some other type that has not been adequately specified).
