I had some machinery that used Diazed fuses, which are rated for 10kA breaking. Replaced with minature circuit breakers of similar rating, as I got annoyed with fuses popping randomly on switch on as they aged, and with replacements costing more than the mains rated breaker. As a bonus I got 3 phase tripping, which made things easier as a blown phase fuse could give strange faults. I later upgraded the supply side to add a 3 phase ELCB, and had to replace industrial heater elements that had developed non tripping leakage to the housings. Extra protection is always good.
I did see a Fluke 77 that was used by Eishkom worker to measure a 11kV line. The fuse survived, along with the battery and the display. The inside of the case had a lovely copper coating, and a PCB that had absolutely no copper traces, except for the solder pads, in the lower section. That came in as a warranty claim.
The lift at work still has Diazed fuses, and I used the spare fuses I had to replace those that had been "modified" by assorted lift mechanics if the blew, so as not to have fuses with external wire elements.
