Eaton DC surge suppressors protect electrical systems against damage caused by voltage spikes and surges during lightning strikes or power outages. They are used in conjunction with other electrical ...Read More
When a surge occurs, the MOV acts as a shunt, diverting the excess current from the electrical system. The MOV's resistance changes with the voltage level, allowing it to effectively limit the voltage across the component. Once the surge has passed, it returns to its normal resistance, allowing the electrical system to work normally.
