Fuses

Fuses are a form of electrical protection device that is designed to protect electrical circuits from overload or short circuit conditions. Fuses come in various types, sizes, and styles, and are designed according to the specific application and protection requirements of the circuit being protected. 0202.250URG fuses are a type of selective current limiting fuses for AC and DC applications. In this article, we will discuss the application field and working principle of 0202.250URG fuses.

Application Field

0202.250URG fuses are a type of current limiting medium voltage fuses that are suitable for AC and DC applications. These fuses are specifically designed for high-current and medium-voltage applications, and are suitable for applications in transformers, circuit breakers, switchgear, and more. With a rated voltage of up to 50kV and an interrupting rating of up to 200A, these fuses provide effective and reliable protection in these types of applications. They are also designed to be easily installed and can be retrofitted to existing installations for added convenience and cost savings.

Working Principle

0202.250URG fuses are designed to protect electrical circuits from overload or short circuit conditions. These fuses operate in a selectivity principle that is based on the energy releasing limiters. When an overload or short circuit occurs, the energy releasing limiters open and release stored energy. This energy is then released as arcs, which are then quickly extinguished by the air gaps. As a result, the circuit is quickly disconnected, thus providing effective and safe protection against overload and short circuit conditions. Additionally, the current limiting feature of these fuses helps to minimize the amount of damage caused by the overload or short circuit.

Conclusion

0202.250URG fuses are a type of current limiting medium voltage fuses that are suitable for AC and DC applications. These fuses are designed for applications in transformers, circuit breakers, switchgear, and more, and are designed to provide effective and reliable protection against overload and short circuit conditions. The selectivity principle of these fuses helps to ensure the circuit is quickly disconnected in the event of an overload or short circuit, while the current limiting feature helps to minimize the amount of damage caused by these events.
