Circuit Breakers

Circuit breakers are essential components of any electrical system that protect the electrical system from overloads and possible safety risks. The IEGM066-28281-2 is an automatic air circuit breaker manufactured by Siemens and is designed to meet the international standards for safety and reliability in all areas of industrial application. This article will cover the application field and working principle of the IEGM066-28281-2.

Application field of IEGM066-28281-2

The IEGM066-28281-2 is primarily designed for use in medium voltage distribution systems. It can be used in a range of industrial applications including power plants, refineries, offshore operations, power generation, and manufacturing. As the air circuit breaker is extremely reliable and can withstand extreme environmental conditions, it is also suitable for use in hazardous areas. Due to its modular design, the IEGM066-28281-2 is a highly versatile device and can be adapted to the requirements of almost any industrial application.

Working Principle of IEGM066-28281-2

The IEGM066-28281-2 is an air circuit breaker which operates on the principle of thermal-magnetic tripping. Tripping occurs through the combination of magnetic tripping, which is activated by an increase in current, and thermal tripping, which is activated by an increase in temperature. When the current level or temperature of the circuit reaches the tripping level, the IEGM066-28281-2 will automatically reset itself one cycle of current after it trips. The trip time is adjustable and can be set to respond in 2 to 5 cycles of current. This feature ensures that the breaker does not trip unnecessarily due to low current transient overloads.

In addition, the IEGM066-28281-2 offers several additional safety features. The electrical contacts of the device are dielectric tested to ensure that no dangerous electrical shock is received by any of the operators that handle the device. The IEGM066-28281-2 is also equipped with a built-in arc chute that is designed to dissipate any arcing that occurs, further increasing the safety of the circuit. Lastly, the IEGM066-28281-2 is also equipped with an automatic reset feature that will reset the breaker if it has been set without manually doing so.

Conclusion

The IEGM066-28281-2 is an air circuit breaker that is highly versatile and robust. It is suitable for a wide range of industrial applications and is suitable for hazardous areas. Its thermal-magnetic tripping system ensures that the current or temperature of the circuit does not overload and results in tripping the breaker. In addition, the IEGM066-28281-2 offers a built-in arc chute, dielectric testing, and an automatic reset feature that make it a safe and reliable option for many industrial applications.
