Circuit breakers are electrical safety switches designed to protect electrical systems and associated components against overcurrents. The IEGHF66-34545-25B-V is a type of high-voltage electric circuit breaker with a high current rating and a low voltage rating. It is mainly used in distribution networks and high-voltage electric systems to protect the system from short-circuiting. In this article, we will discuss the application field and working principle of the IEGHF66-34545-25B-V circuit breaker.

Application Field

The IEGHF66-34545-25B-V circuit breaker is mainly used in distribution networks and high-voltage electric systems. It is suitable for applications in power plants and substations, where its main purpose is to protect the system from short-circuiting. This type of circuit breaker can also be used in industrial and commercial installations, such as factories and shops, in order to protect equipment and personnel from any potential electrical hazard. Additionally, this type of circuit breaker can be used in residential buildings to provide reliable and efficient protection to the electrical system.

Working Principle

The IEGHF66-34545-25B-V circuit breaker is designed to protect electric systems from short-circuiting and overcurrents. It works by sensing a current overload and then cutting off the power supply in order to protect both the electric system and the human personnel and equipment associated with it. The mechanism for this is as follows: when an overcurrent is detected, the circuit breaker’s contacts open, breaking the circuit and thus cutting off the power supply. The circuit breaker can also be reset manually, allowing the user to restore the supply of power if the fault has been fixed.

The circuit breaker is designed to trip once the overcurrent reaches a predetermined level. This level is determined by a set of current sensors, known as trip coils. These trip coils are wired onto the circuit breaker and are responsible for measuring the current flowing through the circuit. If the current reaches a certain threshold, the trip coil will activate the circuit breaker’s contacts and trip the circuit. Additionally, the circuit breaker also includes an overload protection device, which prevents the trip coil from being accidentally activated.

Conclusion

The IEGHF66-34545-25B-V is a high-voltage electric circuit breaker that is mainly used in distribution networks and high-voltage electric systems in order to protect the system from short-circuiting and overcurrents. Its working principle is based on the trip coil, which detects an overcurrent and activates the circuit breaker’s contacts to cut off the power supply. The IEGHF66-34545-25B-V circuit breaker is also suitable for applications in power plants and substations, as well as industrial and commercial installations, such as factories and shops, and residential buildings.
