FX0455 is a Fuse Holder, which is a device for holding and supporting the fuses used to protect circuits and equipment. The holder is designed to provide a safe and reliable connection for the fuse during its service life. FX0455 has a variety of applications in different industries.

Application Field

FX0455 is an economical solution for protecting circuits from overload and short-circuit conditions. It can be used in various electronic applications, such as industrial, power supplies, audio equipment, and automotive. It is also used in many residential and commercial establishments due to its reliable performance. It can be used for protection of low-voltage circuits or for applications requiring higher current ratings.

FX0455 is also often used in recreational vehicles to prevent short circuits from occurring in electrical systems. It is designed to secure electric current from the battery to the motor and other accessories, preventing overheating and other issues from occurring.

Working Principle

The basic working principle of FX0455 is to provide a path for current when the fuse is disconnected or interrupted. The holder contains a metal contact plate which is either attached directly to the fuse or encloses a conductor that is connected to the fuse. When a fuse is connected, the contact plate is held in place by two bolts. When current flows through the holder, the contact plate conducts the current and in the process, heats the holder.

When the current level exceeds the rated limit, the contact plate begins to heat up and expand. This causes the contact surface to be pushed away from the fuse holder, thereby disconnecting the circuit which protects it from further damage.

The holder also has a contact gap which is a gap between the two contact surfaces of the contact plate. This gap allows the voltage to slowly decrease and the current to be reduced.[ This prevents the circuit from being over-loaded, as the voltage would have been reduced before it reached unsafe levels.]

Conclusion

FX0455 is an economical, reliable and widely used Fuse Holder. It is designed to provide a safe and reliable connection for the fuse during its service life, and is used in a variety of industries. Its working principle involves providing a path for current and protecting the circuit when the current surpasses the specified limit.
