What does MOV mean?

Metal-Oxide Varistor (MOV) is a common type of varistor. This contains a ceramic mass of zinc oxide grains sandwiched between two metal plates. A varistor (variable resistor) is an electronic component often used to protect circuits against excessive transient voltages by incorporating them into the circuit in such a way that, when triggered, they will shunt the current created by the high voltage away from the sensitive components. A varistor is also known as Voltage Dependent Resistor. A varistor’s function is to conduct significantly increased current when voltage is excessive. only non-ohmic (materials that does not obey Ohm’s law) are usually called varistors.
