Introduction

Fuses are essential components used in electrical and electronic devices. They protect circuits and devices from being damaged due to overcurrent and overvoltage events and are commonly encountered in industrial, commercial and residential applications. In this article, we will take a look at the 3412.0119.26 application field and working principle.

Application fields

The 3412.0119.26 fuse is specifically designed for applications requiring IEC 60269 non-rewireable fuse links. The fuse series are available from 4 to 12A in various body sizes and designs. It is appropriate for domestic and similar general purpose applications with a rated voltage up to 440V and a rated breaking capacity of up to 6kA. Commonly used in domestic equipment with electronic components such as induction cookers, electric ovens, electric air transports and refrigerating appliances; industrial and commercial lighting, heating and air conditioning; laboratory power supplies and more. The 3412.0119.26 fuse can also be used in all three-phase power grids where a limitation of the current flowing through a certain circuit is required.

Working Principle

A 3412.0119.26 fuse comprises of an enclosure, a metal base, an engraved indicator, a plunger and a fuse element. The enclosure is made of plastics and usually designed to occupy two standard DIN rail meter slots or fuse clips that are mounted on the equipment. The bottom of the enclosure is fitted with metal clips in order to be securely attached to the equipment board. The plunger is placed inside the enclosure, which pushes the fuse element in order to open the circuit when the current exceeds the rated current for the past time allowed. The plunger is designed to fit perfectly onto the base to ensure firm contact. When the circuit is damaged or overloaded due to an external factor, the fuse element melts to open the circuit, interrupt the current and cut off the power, thus protecting the device from possible damaging due to overcurrent.

Advantages of 3412.0119.26 Fuse

The main advantage of 3412.0119.26 fuse comes from the fact that it is very easy to install and replace and are relatively inexpensive. In addition, they are very reliable and lightweight, so they can be used in a wide variety of applications and do not need frequent maintenance. Furthermore, it is very safe to use and features a tight tolerance for over current and over voltage.

Conclusion

The 3412.0119.26 Fuses are an integral component of the electrical and electronic circuit and are used to protect it from the damages caused by overcurrent and overvoltage events. Used extensively in domestic, industrial and commercial applications, these fuses are easy to install, replace and require very little maintenance. The plunger inside the fuse opens the circuit when the fuse element melts due to an overload or a fault.
