0256001.M

Fuses are electrical protection devices that protect sensitive and expensive equipment from the damage caused by short circuit and overload. The 0256001.M is a special type of fuse widely used in industrial and commercial environments. It is usually installed at the input side of variable speed drives (VSDs) to protect from the short circuits, overloads, and other fault conditions. In this article, we will discuss the application field and working principle of the 0256001.M.

Application Field

The 0256001.M is a fast-acting fuse designed for use in protecting 3-phase variable speed drives from over-temperature, overload and short circuit conditions. It is available in three different sizes: 1A, 2A and 5A. The 1A size is suitable for use with low power VSDs, while the 2A and 5A sizes are suitable for medium and high power VSDs, respectively.

The 0256001.M is designed to be used with variable frequency drives (VFDs) that use pulsed current control. This type of drive requires a fast-acting fuse that can react quickly and effectively to short circuit and overload conditions. The 0256001.M is the ideal choice for this purpose. It has a low electrical series resistance, making it compatible with all types of variable frequency drives. It also has a very high interrupting capacity, allowing it to effectively protect from short circuit currents.

In addition to its use in variable frequency drive systems, the 0256001.M can also be used in other applications, such as motors, transformers, and power rectifiers. It is also suitable for use in low-voltage AC and DC power supplies. The fast-acting fuse ensures that the equipment is protected from hazardous conditions.

Working Principle

The 0256001.M is a fast-acting fuse with a pressure-sensitive element. When the electrical current flowing through the fuse exceeds the rated current value, the element melts and interrupts the flow of electricity. This prevents any further current from flowing through the fuse and into the protected equipment. This process happens very quickly, limiting the amount of damage caused by the overcurrent.

The 0256001.M can be reset after it has been tripped. In order to reset the fuse, a current must first be applied to the reset pin. This current will cause the pressure-sensitive element to reform, allowing the flow of electricity to continue. The fuse must be replaced after it has been tripped more than three times as this indicates that the fuse has reached the end of its useful life.

Conclusion

The 0256001.M is a fast-acting fuse designed for use in protecting 3-phase variable speed drives from over-temperature, overload and short circuit conditions. It is available in three different sizes and is suitable for use with low, medium and high power VFDs. The fuse has a pressure-sensitive element that melts when the current exceeds the rated current value, interrupting the flow of electricity and preventing further damage.
