August,<br>
Precisely. And it's a dumb idea, I know. But it's part of a
utility-scale RFP, and it specifically calls out switching the DC
input. This is too early a stage in the process to figure out better
approaches; first we have to qualify for the job. <br>
<br>
Surprisingly, Boltswitch makes one, and it's cheaper than SqD. So we
may have found an answer, but I'm still listening for other ideas.<br>
Thank you,<br>
Allan<br>

<b>Subject:</b> [RE-wrenches] 600VDC Safety Switch question<br>
</font><br>
</div>
<div>Wrenches,<br>
We need recommendation of a 200A or larger (400A or 600A preferred)
two-pole or <span
style="font-family: 'Times New Roman'; font-size: 12pt;">
three-pole, double-throw, 600VDC rated, </span><span
style="font-family: 'Times New Roman'; font-size: 11.5pt;">manually
operated</span><span
style="font-family: 'Times New Roman'; font-size: 12pt;">, load-break-
and load-make-rated, service-equipment rated, fusible or nonfusible
safety switch for purposes of switching DC input. <br>
<br>
</span><span style="font-family: 'Times New Roman'; font-size: 12pt;">Square
D 82345R and H82345 are rated only 250VDC in a fine-print note in their
catalog.
</span><span style="font-family: 'Times New Roman'; font-size: 12pt;"><br>
<br>
I don't think that what I'm asking for exists, but wiser Wrenches may
prevail. Can anyone suggest another brand and product model that meets
these requirements?<br>
<br>
Thank you,<br>
Allan<br>
