Overview

0674002.MXE (also known as MXE-Type) are medium-voltage fuses designed for use in industrial applications, such as electric power distribution systems, transformers, and motor starters. They offer excellent protection against short-circuits, harmonic distortion, and other faults. This article will discuss MXE-Type fuse application fields and working principles.

Application Fields

MXE-Type fuses are generally used in low-voltage and medium-voltage systems for overload and short-circuit protection. They can be used for up to 38 kV and are available in a range of current ratings, from 600 to 5000A. When correctly selected for the application, they provide reliable protection of both the equipment and the operators.MXE-Type fuses are typically used in commercial, industrial, and residential applications. In commercial buildings, they are frequently used in air-conditioning and refrigeration systems, while in industrial plants, they are typically used in electric power distribution systems, transformers, motor starters, and variable-frequency drives. In residential applications, they are commonly used in circuit-breakers and bus bar systems in order to protect against domestic outages.

Working Principles

At normal operating conditions, the current through MXE-Type fuses is small and does not exceed their rated value. However, when the current through the fuse exceeds its rated value, the fuse link melts and the fuse element disconnects the circuit, thus preventing further current flows and protecting the connected equipment from damage.The operation of the MXE-Type fuse is dependent on its melting properties. When a current passes through a colored fuse link, the rising temperature of the link causes it to melt and break the circuit. This speed of the current through the fuse is an important factor in determining the fuse’s melting properties. The faster the current (than the rated current), the quicker it will melt and open the circuit.

Conclusion

MXE-Type fuses are designed to provide reliable protection for electrical equipment and operators. They are suitable for low-voltage and medium-voltage applications, and have a range of current ratings, from 600 to 5000A. The fuse link melts when the current through it exceeds the rated value, thus breaking the circuit and protecting connected equipment.
