Introduction

This article will focus on the application fields and working principle of FP200 electrical fuses. Electrical fuses, or commonly called fuses, are overcurrent protection devices used in electrical systems. They are designed to prevent an excessive current from damaging the devices connected to an electrical circuit. When the current carried by a circuit becomes excessive, the fuse blows and interrupts the flow of electric current in the circuit. Different types of fuses are used for different applications, including residential, commercial, and industrial ELECTRICAL applications.

FP200 Fuses Overview

FP200 fuses are a type of specialty fuse designed for residential applications. Their special design allows them to be used in both linear and nonlinear loads. These fuses have a high AIC (Amperes Interrupting Capacity) rating, making them ideal for high current applications. Due to their high AIC rating, FP200 fuses are often used as general-purpose circuit protection devices for residential applications.

Application Fields of FP200 Fuses

FP200 fuses are most commonly used in residential applications. They can be used as general-purpose circuit protection devices for any type of residential demand, from motor circuits to general lighting circuits. They can also be used for air-conditioners, instant water heaters, dishwashers, and any other electrical appliance that requires a high AIC rating. Furthermore, FP200 fuses can also be used as underground service entrance distribution equipment.

Working Principle of FP200 Fuses

The working principle of FP200 electrical fuses is based on the Joule heating effect. When current passes through the fuse element, it generates heat due to resistance. This heat builds up and eventually heats up the fuse element until it melts and breaks the circuit. The fuse element is designed to melt and interrupt the flow of current in the circuit at the predetermined current rating. The maximum amount of current the fuse can handle before it melts and interrupts the circuit is called the “Amperes Interrupting Capacity” (AIC) rating.

Conclusion

FP200 electrical fuses are versatile specialty fuses designed for residential applications. Normally, these fuses are used as general-purpose circuit protection devices for high current applications. They work based on the Joule heating effect, by interrupting the flow of current in a circuit when the predetermined current rating is exceeded.
