What is a low cost DC Disconnect non-fusable for use near panel strings to meet county code? Ideally it will be NEMA 4 so it can be mounted easily, but NEMA 3 is OK but those usually need to be mounted horizontally. 30A would be good, but something close will be fine.

Good question. I might suggest reading through the following article and discussion as it links to and breaks down some key points in DC disconnect selection.
