I have to agree with Dan. Making disconnects that can open 1000vdc under
load as compared to 600vdc under load will be far more pricey. To "Rate"
all gear for 1000vdc will be prohibitive.

Hello Chris,
From a manufacturer's perspective .. you're incorrect on all assumptions.
(Sorry.)
It costs more to make higher-voltage anythings.
Higher voltage means: Clearance / creepage distances are larger (thus
bigger
parts or products). Insulation must be thicker (or have a higher
dielectric rating).
This results in more rigorous (consequently more expensive) UL
testing. Etc.
All adds up.

As we see more 1000V installations, chances are that 600V rated
equipment will find its way into installations it is not rated
for. To avoid problems and so we don't need two SKUs and lots more
inventory, the manufacturers need to move all their product to
1000V ratings. I suspect it does not cost more to make 1000V wire
than 600V, similarly disconnects, fuses, fuse holders and connectors.
