Circuit breakers are an essential component used for electrical protection. The IEGS6-30890-2-V is a circuit breaker specifically designed for industrial applications, such as power plants, oil rigs, and factories. The IEGS6-30890-2-V is known for its high performance and reliability, and its ability to provide comprehensive protection from overload and short-circuits. This article will discuss the application field and working principle of the IEGS6-30890-2-V circuit breaker.

The IEGS6-30890-2-V is a three-pole terminal operated circuit breaker with an adjustable thermal/magnetic trip unit. It is designed for direct or indirect current applications and is rated for up to 1000V AC or DC, three-phase operation. The adjustable thermal/magnetic trip unit enables the protection of the circuit against overload and short-circuit. The rated current of the IEGS6-30890-2-V is up to 400A and its operating temperature range is between -50° C and 60° C.

The application field of the IEGS6-30890-2-V is primarily in industrial applications. It is often used in places such as power plants, oil rigs, and factories, where there is often a need to protect circuits against overload and short circuits. It is also used in other places where high-performance, reliable circuit protection is needed, such as in military and aerospace applications, as well as medical equipment.

The working principle of the IEGS6-30890-2-V circuit breaker is based on the combination of thermal and magnetic protection. The thermal protection comes from the breaker\'s internal temperature detection element. This element monitors the temperature of the breaker and will trip the breaker automatically if the temperature of the breaker goes too high. The magnetic protection is provided by the adjustable thermal/magnetic trip unit. This unit monitors the current in the circuit and will trip the breaker if the current reaches a pre-set limit.

When the breaker is open and the current is higher than the pre-set limit, the trip unit will close the contacts of the breaker and thus disconnect the circuit. The trip unit also has an adjustable time-delay feature that enables it to delay the tripping of the breaker if the current passes the pre-set limit, but then decreases again, preventing false tripping of the breaker. This feature is especially useful in cases where short duration overloads and short-circuits may occur.

In conclusion, the IEGS6-30890-2-V is a three-pole terminal operated circuit breaker specifically designed for industrial applications. It is capable of providing reliable and comprehensive protection against overload and short-circuits due to its combination of thermal and magnetic protection. Its adjustable time-delay feature enables it to prevent false tripping of the circuit breaker and its rated current is up to 400A making it an excellent choice for many types of industrial applications.
