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. <br>

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

<div dir="ltr">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.</div>
