Circuit breakers are an essential component of modern electrical networks, providing an important measure of protection against electrical hazards. The IEGF6-35876-25-V is a type of circuit breaker designed to provide high levels of reliability and protection in medium voltage (MV) applications. This article will discuss the application field and working principle of the IEGF6-35876-25-V circuit breaker.

Application field of IEGF6-35876-25-V

The IEGF6-35876-25-V is designed for use in medium voltage switchgear. It is designed for outdoor use in both dry and damp environments, and can be used in environmental temperatures ranging from -50°C to +55°C. The IEGF6-35876-25-V offers excellent resistance to electrical disturbances, making it well-suited for applications in which protection from such disturbances is crucial. Its rated operational current is up to 6000A, making it suitable for a wide range of applications.

Working principle of IEGF6-35876-25-V

The IEGF6-35876-25-V circuit breaker works on the principle of air gap switching and operates by opening an air gap between the contacts of the breaker and the equipment. When an overcurrent occurs, the overload current causes the contacts of the breaker to open, forming an arc across the air gap. The arc then quenches, resulting in an interruption of the current. The IEGF6-35876-25-V has the ability to control the rate of the arc quenching, ensuring a safe and efficient interruption of the current. This is particularly useful for preventing oscillations and power surges.

The IEGF6-35876-25-V is also equipped with a protection feature called the instantaneous protection. This feature detects any dangerous levels of current and acts to limit further damage caused by overcurrents or short circuits. This feature is set to trip within 0.1 seconds, providing quick, reliable protection from any potential hazards.

The IEGF6-35876-25-V is also equipped with a thermal protection feature. This feature is designed to protect the circuit breaker from overheating due to prolonged exposure to high currents. This feature operates by sensing the temperature of the breaker, and, if exceeded, quickly activating the breaker’s thermal protection device in order to reduce the current.

Conclusion

The IEGF6-35876-25-V circuit breaker is an excellent product for medium voltage applications due to its robust design, excellent protection features and wide range of operational current ratings. It is designed for outdoor use, making it suitable for a wide range of applications, and provides excellent protection from electrical disturbances. Its advanced protection features, including instantaneous and thermal protection, ensure reliable performance and safe operation.
