I've used these winches on my work trucks (PWs) for several years and they are great.
I overloaded one once and the thermal protection switch worked out quite well; I needed to pull my PW over a bunch of very large rocks (it was ugly & the rockers got mangled) and it prevented me from toasting the winch or charging system, while still allowing me to extricate the truck.
