Distribution MOV overvoltage protection
An MOV, or Metal Oxide Varistor, is a voltage suppression and overvoltage protection device that clamps a transient in an electrical circuit. It is also called a Varistor, or variable resistor, because its resistance changes with applied voltage.
An MOV is a voltage dependent device which has an electrical behavior similar to back to back zener diodes.
When exposed to high voltage transients, the MOV's resistance changes from a near open circuit to a very low value, thus clamping the transient voltage to a safe level.
The potentially destructive energy of the incoming transient pulse is absorbed by the Varistor, thereby protecting vulnerable circuit components.
