I don’t know that I have seen one that works the way you are asking. I think I would probably just do a standard dual feed telecom panel (http://www.trimminc.com/dc-power-distribution/gmt-fuse-panels&filter=ATTRIBU=-%252F%252B24-48V+DC=21=Nominal+Voltage@@ATTRIBU=2=23=Number+of+Buses <http://www.trimminc.com/dc-power-distribution/gmt-fuse-panels&filter=ATTRIBU=-%2F%2B24-48V+DC=21=Nominal+Voltage@@ATTRIBU=2=23=Number+of+Buses>) and then add my own fuses inline where I wanted to feed a single input device.
It’s pretty simple to put a diode inline using a soldering iron or butt splices.
