5TT 1.25 Application Field and Working Principle

Fuses are overcurrent protection devices that are designed to open a circuit should an overload, short circuit, or ground fault take place. The 5TT 1.25 is a type of fuse that is used in the appliance, tool, and automotive industries. It is designed with a special thermoplastic construction and is suitable for protection of up to 20 amps. This tutorial will discuss the application field and working principle of the 5TT 1.25 fuse.

Applications

The 5TT 1.25 fuse is mainly used to protect circuits in the appliance, tool, and automotive industries. The fuse is able to protect against overload, short circuit, and ground fault conditions. Therefore, it is ideal for a wide range of applications, such as protecting the power supplies of washing machines, microwaves, ovens, toasters, drills, power saws, and more. The fuse can also be found in automotive electronics, protecting wires and components from damage caused by over-current problems.

Working Principle

The 5TT 1.25 fuse works by using a thermoplastic body that is filled with a mixture of tin and lead alloy. The alloy is a liquid conductor with a melting point of approximately 119°C. When a circuit is overloaded or a short circuit or ground fault takes place, an excessive current flows through the fuse. This causes the alloy to heat up and eventually melt, thus opening the circuit and preventing further damage. Once the fuse has melted, it must be replaced with a new one. A new fuse must be of the same rating in order to ensure the best possible protection.

Conclusion

The 5TT 1.25 is a type of fuse that is designed for the appliance, tool, and automotive industries. It is a thermoplastic body filled with a tin and lead alloy which acts as a liquid conductor and has a melting point of approximately 119°C. When an overload, short circuit, or ground fault occurs, the alloy melts and opens the circuit, preventing further damage. Once opened, the fuse must be replaced with one of the same rating.
