[RE-wrenches] 600VDC Safety Switch question

[August Goers]

Allan -

What is the application? Are you trying to switch a large PV array before the inverter but after the strings have been fused and combined?

Subject: [RE-wrenches] 600VDC Safety Switch question

Wrenches,
We need recommendation of a 200A or larger (400A or 600A preferred) two-pole or three-pole, double-throw, 600VDC rated, manually operated, load-break- and load-make-rated, service-equipment rated, fusible or nonfusible safety switch for purposes of switching DC input.

Square D 82345R and H82345 are rated only 250VDC in a fine-print note in their catalog.

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?

Thank you,
Allan
