For 48VDC I would actually prefer to see MOVs rather than (or in addition to) silicon avalanche diodes. You’d never put an MOV across an Ethernet data line, but this is power, and MOVs can take a punch.
Purewave used to recommend a device I think the model number was PP1, I don’t know who made it, and it doesn’t appear to be sold anymore. But it had MOVs and maybe some other stuff. Also had a light you could see from the ground which was surprisingly useful. I don’t think it had an internal fuse. I’d probably put that at the bottom, and maybe not a second surge protector.

I don't know much about the device, but after several years of lightning seasons nothing had exploded. That device was actually chosen due to a physical space restriction and not because it was believed to be better. I had looked at the McCown Tech SS as well, but same space limitation applied as the Transtector. (I was mounting on the inside of a cabinet door, and there was a limit on thickness of the housing). Transtector is basically the name brand in this field though. You won't get fired for buying the Transtector.

I have seen these mentioned previously on this list: https://www.winncom.com/en/products/1101-626 Anything else I should be looking at?
