0229.350VXP Application Field and Working Principle

Introduction

Fuses are an important electrical device that contains movable components which instantly separate electrical circuits should an overload or short circuit occur. The 0229.350VXP is a type of terminal style, time-delay, or low interruption application fuse. It is utilized for protecting motors, transformers, capacitors, and cables. Let’s learn more about it by examining its application field as well as its working principle.

Application Field

The 0229.350VXP is used to protect any combination of applications that contain a system with a motor, transformer, capacitor, and/or cable. It is especially beneficial for motor-related applications, as it offers more protection against thermal damage due to a slower speed that shuts down the circuit in the event of an overload, short circuit, or both. It also functions in the same manner for capacitors, transformers, and cables, by providing greater safety and security for overloading.

Working Principle

The 0229.350VXP utilizes a thermal-magnetic trip system. When an overload or short circuit occurs, the thermal element of the device will expand, allowing the movable components to separate the jointed electrical connections. This instantaneous action of the 0229.350VXP prevents more severe damages due to excessive current. The delayed action of the magnetic trip also compounds to the protection system of the fuse.The fuse is built with two separate metallized films inside-- a Current Sensing Element (CSE) and a Thermal Element (TE). When the current passes through the CSE, a magnetic field is being produced, causing a mechanical system of vane to move over the TE element. The TE will expand with the increasing current until it reaches the maximum limit, and the circuit will be shut down. After the system cools down, it will relearn the thermostat and automatically begin the process again. Thus the 0229.350VXP is able to offer maximum protection while giving economical and stable protection.

Conclusion

The 0229.350VXP is a versatile terminal-style, time-delay, or low interruption application fuse, designed to offer maximum protection for motors, transformers, capacitors, and cables. It utilizes a thermal-magnetic trip system that functions when the current surpasses certain limits. With such protection as well as economical and stable security benefits, it is suitable for a variety of electrical applications.
