I dont know of a "prefab" unit.
You need a forward/reverse contactor set with overloads. You are going to keep the phase rotation the same at the top and bottom. One side goes low, the other high.
Make sure its mechanically and electrically interlocked- because its more then likely a Wye/delta wound motor. I would use a rocker type switch, this adds another layer of protection over two individual switches.
You may also want to run a transformer off a/b for control power. And dont forget to fuse all this.
People always call prophets crazy- just ask Charlie.
