You may be reinventing the wheel
A little information is required…
1. What type of Electrical Panel is in your home? Fuses or Circuit Breakers..How old if Circuit Breakers? If a newer panel, it may already have protection
1a. A power strip may be false security..is it a Surge Protector or a Surge Suppressor? “What is the difference between a surge protector and surge suppressor? Surge protector avoids voltage spikes in electrical devices while Surge suppressor regulates the voltage making power constant if a splurge occurs.”
2. The ZW-L has fault detection and protection built in that monitors the track, and any issues that might occur from that part of the system…but in-line protection to your track, can add peace of mind.
I am not certain on the Amp/Current rating that the ZW-L trips at, on each throttle…or the speed it trips the internal breaker…but they do make in-line fuses that trip ultra fast…

I run MTH DCS with an MTH Z-4000…and I have no in-line fuses to my track, because the MTH built in protection is fast and reliable…
one concern is that you add fast acting protection and it “acts to fast”, which interferes with your railroad operation enjoyment…because it trips at the slightest issue or it’s rated to low…
But, it’s your peace of mind (or that of your significant other😁) that matters here…my wife is always concerned about Fire risk…to the point of being a “Karen”…and it does not help that her name actually is “Karen” 😀
But once I start recording-she stops…so that’s a blessing😁
Here’s my MISC
The Manchester Intermodal Service Center…I run alternating power blocks with parallel feeds-to 12 sections.
