Looking For Large DC Rated Safety Switch

Looking For Large DC Rated Safety Switch

Looking For Large DC Rated Safety Switch

(OP)
Is anyone using a high current DC rated safety switch to disconnect a battery bank from a load?  Operating conditions is 300 VDC and 265 Amps.

RE: Looking For Large DC Rated Safety Switch

If in the USA, Pringle is one manufacturer.

Now-ad-days DC circuit breakers manufacured by Square D are common in large UPS applications.

RE: Looking For Large DC Rated Safety Switch

What do you mean by safety switch? There are a few suppliers of load-break switches for DC duty, but they are large and expensive. Please define requirements a bit more.

RE: Looking For Large DC Rated Safety Switch

Most all of the major manufacturers offer this, but to get above 250VDC rating you need to look at the heavy duty 600V rated units. I just checked the Square-D catalog and they go up to 1200A @ 600VDC. Click here and then hit the "NEXT" button near the top-right of the page for 600VAC/DC
I'm sure that Siemens, Cutler Hammer, GE etc. all follow suit.
