I have been on a quest for some high current DC breakers for my solar project. While there are solar specific breakers out there, they cost a fortune so my search ended up sending me to Ali Express where i found some 125A 250V DC breakers direct from the manufacturer. First impressions are that they might actually be capable of their ratings and at $12 each shipped i cant complain about the price.
