Fuses: 0673.500DRT4P Application Field and Working Principle

Introduction: Fuses are widely used in fields like automotive, power distribution, and electronics protection, to ensure the safety of circuits and prevent damage to connected equipment. Every fuse has its own specification and application field. This article will discuss the application field and working principle of 0673.500DRT4P Fuse.

Application Field

The 0673.500DRT4P Fuse is widely used in industrial applications. It is suitable for industrial, mining and public safety equipment, such as air conditioning units, power supplies, medical equipment, motor controls, etc. The 0673.500DRT4P Fuse can also be used as a secondary overcurrent protection device for power supplies.

Features

The 0673.500DRT4P Fuse has a long life and high interrupting capacity. It is made of high quality and reliable material, with features such as:

• Response time (time to open the fuse): < 4 ms at rated current.
• Rated current: 5 A.
• Rated voltage: 500 V.
• High breaking capacity: 200 A.
• Dimension: 15.9x4.3x1.5mm.

Working Principle

The 0673.500DRT4P Fuse works on the principle of melting internal element. When the current through the fuse passes beyond the rated current, the internal element in the fuse melts and opens the circuit. This breaks the current path and thus, prevents any damage from occurring to the connected equipment.

The fuse has a small melting element inside, which is made up of a material with high melting temperature. The melting element is connected to a metal ribbon, which can withstand the full voltage of the circuit. When the current passes through the fuse, it generates heat in the melting element. When the temperature of the element reaches the melting point, it melts and breaks the current path, thus stopping the current flow.

Conclusion

The 0673.500DRT4P Fuse is used for industrial applications. It has a long life and high interrupting capacity. It works on the principle of melting internal element. When the current through the fuse passes beyond the rated current, the internal element melts and opens the circuit, thus breaking the current path and preventing any damage from occurring to the connected equipment.
