These fuses have a higher interrupt rating than standard fuses, meaning they can safely interrupt the high inrush current without causing damage to the electrical system.
PFC (Power Factor Correction) is a technique to improve the power factor of an electrical system by reducing the amount of reactive power (also known as 'wattless power') and increasing the amount of real power.
Reactive power refers to the power consumed by inductive loads, such as motors, transformers and lighting systems. Real power, on the other hand, is the power consumed by resistive loads, such as heaters, incandescent light bulbs & appliances.
