Talk to the people at Ametherm. Sometimes you use them as sensors to control something else like a MOSFET. I am far from expert at kilowatt class power supplies.
But I think today if designing something like that where a multi-KW supply is involved they use microcontrollers and sensors so the startup is sequenced. Most of my work now uses LiPo battery power. Surge is an issue there too as these batteries, even a small handheld one can source 100+ amps and instantly vaporize #8 wire. I use fuses to protect the wire as a backup to something smarter as fires are really bad when it comes to lithium batteries. I tried to put out a burning battery once - basically, all you can do is move it outdoors and wait. This surge issue just does not go away.
