Customer bought a 400 amp switch because of 400 amp meter. Overload protection is 2 200 amp mains. Need 2 200 amp 120/208 switches. Lead time from the factory 4-6 weeks!

I'm sure ASCO, GE, some third party manufacturer is going to have what you need in stock somewhere, 2 wire start of course but that is to be expected with 120/208 anyway, correct?

Check Thomson as well. 
I have a 400a single phase.  It looks like high quality and works well so far.
