FM09B250V1-2A

Electrical equipment has a need for protection from short circuits and other electrical occurrences which can cause damage or fire. Fuses are safety devices that contain a thin strip of conductive metal, typically copper, which melts when the current is higher than the rated value, breaking the circuit and preventing damage. The FM09B250V1-2A is a type of fuse specially designed for industrial applications and as part of motor control systems. It has an operating voltage of 250 to 600 VAC, a current range of 2 to 20A, and a breaking capacity of 1250A.

Applications

The FM09B250V1-2A fuse is typically used in industrial motors, air compressors, air handling units, circuit breaker panels, and other areas where higher currents are used. It can be used in combination with other fuses, such as Bussmann or Hellermann Tyton, to provide reliable protection and a long service life. Furthermore, its small size makes it suitable for panel mounting, eliminating the need for bulky external fuse holders.

Working Principle

The working principle of the FM09B250V1-2A is simple, yet effective. When the current in a circuit exceeds the fuse rating, the heat generated by the flow of electricity melts the thin copper strip, effectively breaking the circuit and preventing further damage. This can happen in a matter of microseconds, minimizing the risk of damage or fire and protecting the electrical equipment.

The FM09B250V1-2A has an additional feature, which is the ability to be used as a buss fuse. This means that it can be wired in series with other fuses to provide extra protection. By doing this, the fuse can be used to prevent the overloading of a circuit, as well as protecting against short circuit faults. This feature makes it a valuable addition to motor control systems, particularly in areas such as automotive or industrial applications.

Conclusion

The FM09B250V1-2A is a specialty fuse specified for industrial applications. It has a voltage range of 250 to 600VAC, a current range of 2 to 20A, and a breaking capacity of 1250A. It is typically used in motor control systems and other areas where higher currents are used, and its small size makes it possible to use it in panel mount applications. Furthermore, the FM09B250V1-2A has the ability to be used as a buss fuse, providing extra protection against overloading and short circuit faults.
