Automatic Switches?

[Seth Mattinen <sethm () rollernet us>]

I hate to interrupt the IPv6 and RFC 1918 mega-threads...

Does anyone know of a company that makes 208v (3-wire line-line ground,
no neutral, 208v loads only, single phase) 30-60 amp automatic transfer
switches with sub-30ms switching time? APC used to make the SU045X163
30A model, but it seems to have been discontinued and it's hard to find
products that support 208v single phase.
