Fuses: 142.0020.6122 Application Field and Working Principle

Introduction

Fuses are electrical devices consisting of two or more conductive elements that open a circuit when a current over the specified threshold flows through the device. They are used to prevent damage to electrical components and circuits due to arises from excess current conditions. The name “142.0020.6122” refers to one type of fuse used for an industrial power distribution system. This article aims to discuss the application field and working principle of 142.0020.6122 fuses.

Physical Description of 142.0020.6122 Fuses

The 142.0020.6122 fuse has a cylindrical shape. It has a black exterior body, which has an embossed design for an easily identifiable visible marking. It also has a long yellow trip lever that indicates whether the fuse is in open or closed mode. Other features of the fuse include a bayonet catch, uniquely shaped hammer-on attachment, a rated short circuit rating and a vibration and shock resistant body.

Application Field of 142.0020.6122 Fuses

The 142.0020.6122 fuses are mainly used for protecting the industrial power distribution systems, providing an efficient current overload protection. They are typically installed in sub-panels and in-line breakers. This type of high current fuses are used in various power systems depending on the magnitude of the current rate of the system. It is more suitable for larger currents, typically from 350 to 600 Amperes, and can be applied as a primary or secondary power protection device. It is also used in three phase power systems, providing protection for all three phases at once.

Working Principle of 142.0020.6122 Fuses

The working principle of 142.0020.6122 fuses is based on the temperature characteristic of the fuse body material. When the increased current flow through the fuse, the temperature of the fuse rise due to the heat loss. When the temperature reach over the defined melting temperature, the melt element of the fuse will open the contact to create a disconnect. This then isolates the power supply or downstream devices from the load, preventing further damage.

Conclusion

The 142.0020.6122 fuse is an important protection device for industrial power distribution system. Its primary application field is to protect the power system from the dangerous conditions of excess current. Its working principle is based on the temperature characteristic of the fuse body material, which opens the contact at the predefined melting temperature. It is highly recommended that this fuse be professionally installed and regularly tested to ensure its safe and effective functioning.
