Dave,

Electrical breakers are driven by current, not voltage.   An over voltage, by itself, will not trip the breaker.   In the example given below it is most probable something downstream would have shorted-out first, causing the draw to spike and trip the breaker.

It could not be plugged to a 220-240 V outlet unless there was a 110-120 V type outlet wired to the 240 V wiring.  In that case, I would expect the breaker in the van to trip as the internal van wiring heated up.  I would check the breaker, reset it if it is tripped, and then try the refrigerator on 110-120 V circuit.  mcneely
