Introduction

Fuses are important components that are used to provide an effective level of protection to electrical systems and components. The type 3AB 100 fuse is designed for use wherever short circuit and overload protection is required in industrial, commercial and residential applications. This article will discuss the application field and the working principle of type 3AB 100 fuses.

Application Field of Type 3AB 100 Fuses

Type 3AB 100 fuses are approved for use in many different electrical and electronic applications. The type 3AB 100 fuse is the standard rating for motor circuit protection. It is also used to protect high amperage circuits such as those used in industrial equipment.Type 3AB 100 fuses can also be used in outdoor equipment such as irrigation systems, portable fans, and electric lawn mowers. These fuses provide greater ratings than other types and are suitable for appliance manufacturers who need heavy-duty protection for their products.

Working Principle of Type 3AB 100 Fuses

The type 3AB 100 fuse has a current rating of 100 amps and a voltage rating of 600 volts. Its size and design are considered ideal for general purpose applications. The fuse is composed of a small, hollow metal tube that contains a strip of metal, usually copper or aluminum.When a current flows through the metal strip, it generates heat. The amount of heat generated depends on the amount of current flowing through the fuse. When the heat surpasses a certain threshold, the metal strip melts and separates, disconnecting the circuit and preventing further current flow. This is the main mechanism by which fuses protect electrical systems and components from damage due to overloads or short circuits.

Conclusion

Type 3AB 100 fuses provide effective protection for electrical systems and components. These fuses are suitable for use in many different applications and are particularly appropriate for motor circuit protection. They are also suitable for use in outdoor equipment like fans, lawn mowers and irrigation systems. The fuse works by generating heat when a current flows through the metal strip contained within it. Once the heat surpasses a certain threshold, the metal strip melts and disconnects the circuit, thereby preventing further current flow.
