3412.0120.26

Introduction

The 3412.0120.26 model is a high-voltage fuse used in a variety of industrial and commercial applications, including general overcurrent protection. This model is especially popular within the electronic protection industry, owing to its compact design and fast response time. This article will discuss the applications and working principle of the 3412.0120.26 model.

Application Field and Working Principle

Application Field

The 3412.0120.26 model fuse is mainly applied to electric power distribution systems, their protection fields include several aspects:

• Short-Circuit Protection: It can immediately deactivate the power supply in case of a short-circuit.
• Overload Protection: It can be used to protect the power system from being overloaded.
• Electro-mechanical Interlock: The fuse provides a means of electrically disconnecting the line from the power source.
• Surge Protection: It protects the system in case of too high voltage.

Besides, the 3412.0120.26 model fuse can also be used in other applications such as power supply for medical equipment, lighting system, security system, and motor control.

Working Principle

Working principle of the 3412.0120.26 model fuse is to act as a heat sink, absorbing the energy generated from a short circuit or overload and diverting it away from the protected circuit. This is done by sand-filled chamber jackets wrapped in an aluminium or copper coil. When the current or voltage exceeds the specified limit, the heat generated causes a thin metal wire inside the fuse to melt, thus disconnecting the power supply.

One of the hallmarks of this fuse is its speed of operation – the interruption time is only several milliseconds. This makes it an ideal choice in determining whether a circuit needs to be interrupted in case of a short circuit. In comparison, traditional fuses usually take several hundred milliseconds or even more.

Conclusion

The 3412.0120.26 model fuse is a high-voltage fuse which is designed for a wide variety of applications. It works as a heat sink to absorb excess energy generated from short circuits or overloads and can quickly interrupt the power supply. This makes it a popular choice in the electronic protection industry due to its reliability and performance.
