It has a voltage dependent resistor (MOV) connected between power and earth line, so when the voltage increases, the resistance of the MOV decreases and the power line surge is kind of shorted to the ground. Maybe someday I will open it and verify all the components and its connectivity.

Nice. But how it protects from surge? What's special inside?
