Bought this 12V 100A contactor from eBay, I thought that the voltage is just for the coil (to turn it on) so I connected a 100V DC with 80A of load and connected the contactor to a 12V input, then it turned on and my amp meter reads 80A (all good so far), turned it off by removing the 12V from the contactor and suddenly I hear a khhhhhh sound and smoke came out of the contactor.
I thought the only thing that matters is the current which I didn't exceed but it sounded like an arching inside when I turned the contactor off.
Will that suite my 100V?

It's rated for 72V (I believe lead acid battery nominal) but will I have to turn the contactor on by connecting 72V to it?
I want to control it with a 12V and have it handle 80A at 100V DC.
