When the voltage divider output goes above 10V (which happens when the supply goes above ~400V), Q1 starts conducting, which in turn makes Q2 conduct and shuts down the mosfet. When the fault disappears, everything goes back to normal, but it takes a longer time. There may be ways to make the circuit simpler.
