I must caution those who are considering the use of touch safe fuse holders in distribution panels. If one of those fuse holders were to be opened under load you will very likely have a fire. Always be sure to only install touch safe fuse holders in such a manner that they cannot be opened by un trained personnel, Those fuse holders are not load break rated.

This seems like a rather stunning oversight—offering a charge controller without any means to integrate it into the BOS built by the same manufacturer.
Just now I laid a 600 VDC rated touch-safe fuse holder over a QOU breaker. The fuse holder is smaller than the breaker so it would fit in the PDP. The fuse holder would be a bit recessed which may look awkward and impede the opening of the fuse holder. I do know you can buy DIN rail of varying height. Maybe you could drill out the rivets on the DIN rail and replace a short section of it with high profile DIN Rail and make a somewhat elegant solution???
Good luck.

Thanks guys,
Just wanted to make sure I wasn’t missing something. Curious that Schneider doesn’t have higher voltage input breakers.

I use the SQD fused disco I mount this next to the CC and use the Flex cobra wire for the low DC voltage and the do have breakers for the context for that

Hi Mike
No breakers I know of that fit the Conext boxes but you could use a MidNite Big Baby and a MidNite 600 volt breaker in it or even a touch safe 1000 volt fuse and holder they’re DIN rail

Supply chain crunches brought on by the pandemic and Omicron’s toll on the workforce are causing shortages of goods. Most analysts agree that rising prices — not just in the US, but also across the world — are largely consequences of the Covid-19 crisis rather than policy errors by governments or central banks.
Infectious waves have closed factories in Asian manufacturing hubs and caused chaos in transporting products to US markets, creating a spike in demand. Also Americans have cash to burn after two years of canceled vacations, closed restaurants and working from home, a major factor supercharging the price surge.

Wrenches,
Can anyone direct me to PV input breakers that are rated up to 600VDC that would work in a Conext Distribution Panel? From what I can tell, Schneider only offers breakers up to 160VDC.
Thanks,
Michael
