Introduction

L15S040.TX100 is a dual-element protective current-limiting (fault current-limiting) fuse. It is manufactured and tested in accordance with IEC and other international standards. TX100 fuses provide reliable and safe protection for circuits. They offer very high current ratings and fast acting protection.

Application Field

TX100 fuses are most commonly used for the protection of industrial electrical networks. They provide reliable protection in applications where large motor circuits, multiple motors, or high-short-circuit currents are present. TX100 fuses are also used in industries such as computer networks, telecommunications, process plants, material handling, and power generation.

Working Principle

TX100 fuses work by limiting the amount of current that is allowed to flow through a circuit. The fuse contains two elements, a current-limiting element and a thermal element. If excessive current flows through the circuit, the current-limiting element will activate and limit the amount of current that passes through to the thermal element. If the current continues to be excessive, the thermal element will also activate and the fuse will open to disconnect the circuit.The current-limiting element consists of a metal coil wound around a hollow copper tube. The tube is filled with a special ceramic material that amplifies the thermal effects of the current. When excessive current flows through the tube, it heats up the ceramic material, leading to an increase in air pressure within the tube. This pressure causes the coil to expand and compress the tube. This, in turn, limits the amount of current that passes through.The thermal element of the TX100 fuse is a piece of metal that is heated by the current that passes through the current-limiting element. If this current is excessive, it will heat up the metal to the point where it will open the fuse, disconnecting the circuit. The temperature at which the fuse opens is determined by the amount of current that is flowing through it, as well as the size of the fuse.

Conclusion

TX100 fuses are a reliable and efficient way to protect electrical circuits. They offer both current-limiting and thermal protection, ensuring that current is limited and that the circuit is safely disconnected if excessive current flows through it. TX100 fuses are commonly used in industrial applications, where their fast-acting protection and high current ratings are essential. They are also used in computer networks, telecommunications, process plants, material handling, and power generation.
