High Energy Absorption Block Metal Oxide Varistor MOV 4700V 70KA MYE70-472 V282BB60
Varistors are voltage-dependent resistors with a symetrical V/I characteristic curve whose resistance decreases with increasing voltage, connected in parallel with the electronic device or circuit that is to be guarded, they form a low-resistance shunt when voltage increases and thus prevent any further rise in the overvoltage.
Varistor is sintered zinc ovide together with other metal oxide additives under specific conditions. Which produces a ploycrystalline ceramic whose resistance exhibit a pronounced dependence on voltage.
It is widely used in railway automatic signal, traffic control center, communication relay station, low voltage power distribution, semiconductor devices and various electrical equipment operation overvoltage protection and atmospheric overvoltage protection.
