Fuseholders are an integral device in any electrical system. No electrical system can function without proper protection against short circuit or overcurrent. The 271.1101.0002 is a type of fuseholder that provides secure and reliable protection to ensure highest possible safety standards. By studying the application field and working principle of the 271.1101.0002, one can identify its key characteristics and assess its performance.

Application Field and Uses

The 271.1101.0002 is a specialized and reliable industrial fuseholder. It can be used for protection against short circuit and overcurrent in various industrial environments, such as machines, pumps and electrical distribution systems. The device is extremely reliable and robust, and it can withstand external forces, such as vibration and shock. The 271.1101.0002 is also equipped with thermal cut-off protection that prevents its internal components from overloading and short circuits. Additionally, the device’s mechanical life is prolonged due to its well-designed mechanical components and its high quality, corrosion-resistant coating.

The 271.1101.0002 is also suitable for a wide range of electrical applications, thanks to its broad voltage range of 250 to 600 volts. It can be used in both single-phase and three-phase systems, and it is perfectly suited for applications that require high inrush currents. Furthermore, the fuseholder is compact and lightweight, and it can easily be installed in tight spaces or concealed areas.

Working Principle

The protection system of the 271.1101.0002 is based on a thermal link and a magnetic trip-off window. The thermal link is electrically insulated and thermally connected with the contacts of the fuseholder. In normal operation, the thermal link remains closed and the fuse can be switched on or off. However, if the current level exceeds the trip-off window’s set point, a magnetic field is generated and the thermal link is opened.

As soon as the thermal link is opened, the connection to the contacts of the fuseholder is disconnected and the fuse is instantly switched off. The 271.1101.0002 also uses a reset button that can be used to reset the thermal link in the event of a short circuit or overcurrent. Additionally, the fuseholder is equipped with an optional alarm relay that can be used to alert operators in case of an emergency situation.

Conclusion

The 271.1101.0002 is an industrial fuseholder that provides reliable protection against short circuit and overcurrent in various environments. The device is equipped with a thermal link and a magnetic trip-off window, which provide fast and secure protection against electrical faults. Additionally, the device is suitable for a broad range of voltage levels and applications, and it is also compact and lightweight. All these features make the 271.1101.0002 a perfect choice for any industrial application that requires secure protection against electrical faults.
