I recommend that you select a breaker about 25% higher than your maximum expected load.

I have different current ratings available, see my other eBay listings. If you want multiple values then put them in your basket and pay for them together, this should ensure that you get the quantity discounts.

If you need high quantities please send me a question and I'll see if I can give you a special discount and send them in a single package.

Feel free to ask any questions that you may have.


If you are looking for a mix of DC breakers, Inrush modules, PV string fuses and SPDs then have a look at my eBay shop and contact me with a list of your requirements. I can put up a custom listing for you with combined quantity discounts and ship it as a single package.
