What can I say, it's a circuit breaker. If there is nothing around, just open the box, like someone took it out of the circuit board and put it in the box, and then added 1 air pocket (i.e. useless packaging). It seems that he miraculously survived during transport. It works, but of course I have no way of testing the operation of the circuit breaker to see if anything inside has been damaged. I've waited too long to consider internal damage, so the return window is closed. I'll return it next time.
