Adding surge protection to custom bar

Hello, I am looking for advice to add full surge protection to a custom power bar with a thermal fuse/MOV and a breaker switch that will trip if any issues arise. I have built several 240v 30 amp extension cords that feed 4x 6-15R in a box, basically a 240v power bar. This is used for high value computer equipment, powered by some server grade 1500w PSUs, or variety of platinum grade 1000-1650W ATX PSUs. these power bars only carry about 3000W of PSU load each. As you can see, there is A LOT of run way as much as 7200W. I did have an issue of 1 PSU dying on me in the middle of the night and it tripped my panel breaker (thankfully an out building). I’d like to somehow convert these power bars into true surge protector bars, that would trip earlier and individually, instead of taking out the whole service. Is there such a product that has all 3 components in 1? a thermal fuse, MOV, and resettable breaker switch, that I could add to the side of my bar? soldering likely required of course.

Thank you for any help you can provide.

Welcome to the Technical Forum. I have sent this to the group to review to see if anyone has any suggestions for this. I will let you know what I find out.

Panel-mountable circuit breakers of a likely type can be found here, and see this post in regard to selection of over-voltage protection devices.
