A varisztor olyan elektronikus alkatrész, ami adott feszültség felett hirtelen vezetni kezdi az áramot. Ezt a tulajdonságát túlfeszültség korlátozására, vagyis az áramkör védelmére lehet használni: az eszköz egyszerűen eldisszipálja a túlfeszültség energiáját.

A varistor is a voltage dependent resistor (VDR). The resistance of a varistor is variable and depends on the voltage applied.

System Variator är ett flexibelt elfördelningssystem som bygger på två grundkomponenter. En fast del: grundenheten (VIC), och en flyttbar del: uttagsboxen (VUB). Tillsammans bildar de en komplett elfördelningscentral.

When the voltage applied to the varistor is lower than its threshold value, the current flowing through it is extremely small, which is equivalent to a resistor with infinite resistance, vice versa. A Metal Oxide Varistor or MOV is the blue or orange-colored circular component that you can commonly spot on the AC Input side of any Power Supply Circuit.The Metal Oxide Varistor can be considered as another type of variable resistor that can vary its resistance based on the applied voltage across it.
