I am not a miner, but I do use surge protection at home, or at least I hope that the devices I've bought do this job good enough.
Most of my surge protectors at home are made by APC. I use mostly this one, but I also have some of this.

Looking for the numbers, I've seen that this looks more powerful = "Peak Current Common Mode 48kAmps", instead of 30kAmps for what I use. However, it's kAmp, not Amp. Do we talk about the same thing? However, take a look there, the technical specs tab looks pretty good, although you may understand more than I do from all those numbers.
