Working Mechanism

  • When the current flowing through the circuit exceeds the rated value of the fuse, the heat generated by the current causes the metal alloy to melt, breaking the circuit and interrupting the flow of current.

Frequently Asked Questions

How are these PFC fuses better than standard fuses?

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.

Are there any safety precautions I should take when working with fuses?

  • When working with fuses, ensure that the power is turned off before handling the fuse.
  • Wear appropriate personal protective equipment.

What is PFC?

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.

What are reactive and real powers?

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.
