In addition, MOV-20D680KTR can protect against the possibility of an electrical spark which can cause an electric shock and potentially cause fire.

Working Principle of MOV-20D680KTR

MOV-20D680KTR is an electronic device prepared by the combination of zinc oxide and other trace materials, which has the ability to control high voltage signals. The device has two plates on its surface, called anode and cathode, which are connected with an insulated substrate called the dielectric. When the voltage applied to the anode and cathode exceeds the designated level, the device actively limits this voltage and dissipates it in the form of heat.

Zinc oxide acts as the main active substances in MOV-20D680KTR, which is in the form of tiny particles or grains, and are suspended in the dielectric between the two plates. When an overvoltage is applied to the anode and cathode, the tiny zinc oxide particles are strongly attracted to the positive and negative electrodes, forming an avalanche breakdown. This creates an electrical channel and disperses the excess energy, reducing the surge voltage. This facilitates the protection of the electrical equipment from overvoltage.

MOV-20D680KTR is an effective form of overvoltage protection, and it has made it possible to protect expensive electronics from power surges, lightning, voltage spikes, and other electrical “surprises”. With its ability to provide overvoltage protection, monitoring, noise filtering, and fire protection, MOV-20D680KTR is an ideal choice for many applications.
