023401.6MXE

023401.6MXE is a type of fuses, used mainly in the electric power distribution network or other requirements of current fuse cut off protection occasions. It features need off-load short-circuit current carrying capacity of up to 40KA. It is designed for use in dc high voltage and low voltage lines that are either distributed or air insulated across power networks.

Application Field of 023401.6MXE

The 023401.6MXE fuses are designed mainly for capacity-restricted distribution lines, including low voltage and medium voltage applications. It features a resistor-like structure that allows it to survive the current surge when the fault is instantaneously cut off without being destroyed. The 023401.6MXE is suitable for power distribution systems up to 2,500A and for high-voltage applications up to 40KV. Its typical applications include:

• High voltage power network fuse protection;
• Short-circuit protection in large 3-phase distribution lines;
• Low-voltage fuse cut-off protection in power distribution systems;
• Overload protection in power distribution systems.

023401.6MXE fuses are used in a wide variety of fields, from conventional electrical power distribution systems, to railway systems, mines, and more. They are particularly popular in urban power distribution systems due to their reliable performance record and high current-carrying capacity. Additionally, 023401.6MXE fuses are often used in protecting components in motor control applications, such as starters, contactors, low- and medium-voltage drives, and adjustable speed drives.

Working Principle of 023401.6MXE

The 023401.6MXE working principle is based on the concept of a resistor–inductor–capacitor (RLC) circuit. This is because when a sudden overload or short circuit occurs, the device\'s resistance-like feature causes the supply voltage to drop, while the inductance-like property causes the stored energy to partially protect the line by providing a smooth closing of the device. When this occurs, the capacitor-like property helps the fuse to absorb the peak current thus enabling the opening of the line.

In addition to the RLC circuit, the 023401.6MXE also has a mechanical element, which is the arcing blade, making it act like a breaker. This arcing blade is set at a certain distance from the fuse body, and is designed to reduce the short-circuit current to the point where it is no longer able to sustain the arc. As the current passes through the fuse, it causes the arcing blade to vibrate and increase the distance between it and the fuse body, thus reducing the current.

Once the current has reached the final cut-off point, the fuse will begin to turn off. This is accomplished by a mechanism called an electromechanical switch, which uses a small electronic circuit called the shut-off switch. The shut-off switch works by sending a signal to the fuse body, which causes it to automatically disconnect the fuse from the line, thereby protecting the line from further damage.

In summary, the working principle of 023401.6MXE fuses is based on a variety of techniques, including the RLC circuit and electromechanical switch. These techniques help to provide instant cut-off protection to power lines, while also offering reliable performance.
