I am digging around to see what options I can find. So far I have looked at...

Schneider Electric Forum Post Here
NHP DINT10H2125C and DTSHT2460V
ZJBeny BD-125

Will keep you posted on what I find.

Update. Ended up going with the ZJBeny BD-125 breaker as it was a much more cost effective solution that complied with the same standards as the Schneider Electric and NHP units.



I received delivery of the BD-125 today, so am now planning the layout for the DC busbars and breakers etc. Will post photos of my progress on here.

Gregoinc, thanks for the info. What's it costing? Are you getting it local or importing it yourself?
I mess with electric everythings in Raglan, NZ.
Here's my battery, 14S12P Leaf G1 Cells with Batrium monitoring
I'm an advocate for The Right to Repair and think you should be too.

I'd be interested in price as well. I ended up buying https://www.ebay.com.au/itm/ABB-SACE-S3-...2749.l2649 as it had the DC shunt release to trigger disconnection via Batrium if it all goes to crap as well as a sensor so batrium can tell what state the breaker is in. I got it for $140, but postage was $80. Ouch. I needed 200A and wanted the shunt release to be DC as I didn't want to mix AC and DC (i.e. use batrium on DC to trigger a 240v AC release).

I managed to purchase the BD-125 through a contact, so probably got it more wholesale than retail. Worked through the numbers and the BD-125 was around $120 AUD delivered to me. The BD-125 I purchased included a shunt trip that is triggered with 24v DC. Opened the box last night, it's a beast of a thing, and I will put up posts in my build thread as things proceed.

You did much better than I did. I ended up paying circa $150AUD plus around $80 shipping from the states for one of the ABB S3 200a breakers. They are an absolute beast! How are you going to mount it? Looks like the ABB can just screw to the wall, but it would be nice in a little enclosure, but I'm just not too  sure what sort of enclosures they would fit in and don't really want to butcher one up myself...

Hi mbrunton,

I have been planning on mounting most of the DC inside a steel electrical enclosure. The picture below is my draft plan for how the devices will attach to the mounting plate inside the enclosure.



The diagram shows the DIN rail for DIN mounted MCB's, BD-125 circuit breaker in the middle, and the positive and negative busbars on each side. I have more design work to go, but that is most likely the basic outline.

Hope this helps.
