Inverter Swap 1000 for 2000watts

New development while i wait for this auction to end. I have found 2 Klixon thermal circuit breakers under the rv where all the battery cables come together and one in the rv between the inverter and the control panel. Google search makes me think they are the self resetting sealed kiind, but does anyone know what these are or if i can try resetting it? They look just like this:
