Circuit Breakers: IEG6-36902-5-V Application Field and Working Principle

Circuit breakers are designed to prevent electrical circuits from overloading and short-circuiting. They come in many different shapes and sizes and are used for a variety of applications. One such example is the IEG6-36902-5-V (5 kV) circuit breaker from Eaton. This particular breaker utilizes vacuum interrupter technology to provide excellent short-circuit current interruption and reliable operation.

The IEG6-36902-5-V is used in medium- and high-voltage applications between 600 V and 5 kV. It is typically used in the utility and industrial markets protecting critical power systems. It is also commonly found in residential, commercial and mobile systems where its performance can help reduce electric utility outage costs and improve system reliability.

The IEG6-36902-5-V circuit breaker is a vacuum-based breaker and uses a vacuum interrupter instead of a traditional, air-based mechanism. Vacuum interrupters are preferred in higher-voltage applications due to their superior reliability and lower maintenance requirements. The vacuum-based breaker also uses a low-profile design, meaning it takes up less space than a traditional breaker.

The IEG6-36902-5-V circuit breaker features a fault-interrupted current rating of 10,000A and a short-time current rating of 50 kAIC. It is designed to perform reliably in any environment, offering reliable and cost-effective protection for medium- and high-voltage power systems. The IEG6-36902-5-V also features adjustable trip settings that are easily attainable with the use of a simple screwdriver.

The working principle behind the IEG6-36902-5-V circuit breaker is relatively simple. When an overcurrent or short-circuit condition is detected, the breaker trips and opens the electrical circuit. This happens because a vacuum arc-extinguishing chamber (VAC) inside the breaker is filled with a vacuum and an electric arc is created when the two contacts are disconnected. This arc is then extinguished by the vacuum and the breaker is reset. The VAC in the breaker ensures that the contact material does not erode and limits the growth of the current-causing arc.

The IEG6-36902-5-V circuit breaker from Eaton is the perfect solution for customers looking for a reliable and cost-effective medium- and high-voltage breaker. Its slim profile and adjustable trip settings make it ideal for both residential and commercial applications. The vacuum-based design ensures reliable protection and fewer maintenance requirements. Overall, the IEG6-36902-5-V is an excellent choice for today’s power systems.
