/diy/ - Do It Yourself

I need a help from a big strong brainy man.
I have this part

Basically from what i understand it is a heater with a thermostat that turns it self off if it reaches over 85C

It says on it 250V 10A, i mean that is A LOT of current for such high voltage.

But it is installed into a food heater that operates on 12V DC power, so that would mean that if you operate it from 12V it would consume fucking 200A and that just can't be right.
I tried measuring resistance ot the in and out contacts and it shows either 0 or no connection, which would be about right since with such massive amperage it has to be short tier tiny resistance.

I am too afraid to connect it to my shitty little DC power source which can only pump out about 30A

So how in the fuck are you supposed to power this tiny thing with just 12V DC?
