Fuses

The working principle of the 047301.5YRT1L Fuse is based on electrical current, resistance, and thermal sensing. When the current reaches certain levels, an internal fuse link becomes electrically heated and opens, which will de-energize the circuit and disconnect the power supply.

The Construction of Fuses

The construction of a 047301.5YRT1L Fuse is made up of several components. An alloy wire, normally made of tin and copper, is typically used as a fuse link. This wire is enclosed in a cylindrical body, most often made of ceramic, glass, or plated metal. The fuse body may contain a non-metallic tube to contain the electro-thermal material, or it may contain a heat soak chamber with a built-in current sensing device. The body may also contain a spring contact to ensure proper contact is made to the electrical circuit.

Thermal Sensing

The 047301.5YRT1L Fuse contains an internal thermal sensing device which senses when the current flow reaches a predetermined level. At this level, the fuse link heats up, and the temperature will increase until it reaches a point known as the fusing temperature. The thermal sensing device then automatically opens the circuit so that the electrical current stops, and the circuit is disconnected from its power source.

Applications of Fuses

The 047301.5YRT1L Fuse can be used for a variety of industrial and domestic applications. These include power wiring systems, motor protection, electrical control panels, as well as low-voltage outdoor lighting systems. Additionally, it can be used in residential and commercial buildings, industrial and manufacturing plants, and electrical and electronic equipment.

Conclusion

The 047301.5YRT1L Fuse utilizes electrical current, resistance, and thermal sensing to protect electrical circuits from current overloads. The fuse contains a fuse link enclosed in a cylindrical body, and a thermal sensing device which opens the circuit once the current reaches a predetermined level. This type of fuse can be used for various domestic and industrial applications, including power wiring systems, motor protection, electrical control panels, and low-voltage outdoor lighting systems.
