3404.0119.24 Application Field and Working Principle

The 3404.0119.24 is a slow-blow, time-delay miniature fuse which is a fundamental component used for over-current protection. This type of miniature fuse is suitable for applications such as home appliances, logic and circuit boards and electronic instrumentation. This type of miniature fuse has a breaking capacity of 20A, and a rated voltage of either 250VAC or 125VDC.

A slow-blow, time-delay miniature fuse provides the highest level of over-current protection for electronic devices. The regular fuse link melts rapidly when a relatively High current flow through it, which is not favorable for most electronic devices. The slow-blow fuse works differently, because when the current flow through it exceeds the rated value of the fuse, instead of instantly melting, an arc is formed in the fuse element that lengthens the time for the over-current. This gives a time-delay in the response of the fuse to the over-current, allowing it to absorb to some extent significant large current spikes, thus providing reliable over-current protection for electronic devices.

In order to meet the special need of different applications, slow-blow, time-delay miniature fuses are manufactured according to standards defined by IEC as well as other international or regional standards. The most common standards regulating the manufacture of this type of fuses are those set up by UL, CSA, VDE, Semko and other national authorities. This type of miniature fuse conforms all the international standards, including both the dimensions and other electrical characteristics.

To ensure the safe operation of an electrical system, the use of the slow-blow, time-delay miniature fuse provides the highest level of over-current protection, and is highly reliable. The reason why this fuse is so reliable is because it is designed to withstand not only extreme temperatures, but also high overloads. In addition, the overall manufacturing quality of the fuse is very high as it is designed to meet the demands of a variety of different applications. The fuse is also very lightweight and does not require much space, making it ideal for applications in tight spaces.

The 3404.0119.24 slow-blow, time-delay miniature fuse provides a reliable, high quality product for use in applications where high levels of over-current protection are needed. The fuse provides a response time that is significantly faster than regular fuses, allowing it to respond quickly to overloads and protect electrical systems from potential damage. As the fuse meets all the standards set up for the manufacturers, it is a reliable, safe, and highly efficient product and is suitable for a variety of applications.
