Circuit Breakers

A circuit breaker is an important component found in various electrical applications, such as residential and industrial applications. IEG66-30616-4-V is a specific type of circuit breaker that has a variety of features and applications. It is designed to provide protection against overvoltage and overloads, as well as to control electrical circuits.

Application Field

IEG66-30616-4-V circuit breakers are designed for switchboards, distribution boards and motor control centers, hybrid up to 1000 volts AC. It is suitable for accessory-party-neutral applications and most commonly used in high-end homes, industrial and commercial electrical installations.

This type of circuit breaker is also used in institutional, industrial and commercial installations. It is also used for external illumination and for the protection of electrical circuit installations from excessive currents due to short circuits or overloads.

Working Principle

IEG66-30616-4-V circuit breakers use a mechanism called the electromechanical trip unit. It works by opening or closing contacts when an overload or short circuit occurs. The trip unit works by measuring either the voltage or current. When the overload or short circuit occurs, the trip unit uses this reading to immediately trip the breaker, disconnecting the affected circuit. The trip unit also contains safety features to prevent inadvertent tripping.

The mechanism of IEG66-30616-4-V circuit breakers combines the strength of electrical contacts with the sensitivity of a solenoid. This type of mechanism provides constant resistance and exceptional sensitivity to overcurrents. It is equipped with an adjustable thermal trip device, which offers protection against overloads, while its magnetic trip also provides fast protection against short-circuits.

Advantages

One of the benefits of IEG66-30616-4-V circuit breakers is the fact that they have a long lifetime, normally in excess of 10 years. Further advantages include their low power consumption, the fact that they are compatible with a wide range of accessories for different applications, their low maintenance needs and their high performance levels.

Conclusion

IEG66-30616-4-V circuit breakers are suitable for a wide range of residential, industrial and institutional electrical installations. Their working principle is based on a electromechanical trip unit that combines electrical contacts with the sensitivity of a solenoid. This circuit breaker model offers a variety of advantages, including long lifetime and low power consumption, and can serve as a reliable and resourceful solution for various electrical systems.
