Circuit breakers are essential components of any electrical system, allowing operators to quickly and safely disconnect and isolate areas of the electrical network, should a fault occur. The IEGH66-1-62-6.00-A-01-V is a popular type of circuit breaker, providing reliable operation while conforming to the relevant safety standards. This article explains the application field and working principles of this popular breaker.

Applications

IEGH66-1-62-6.00-A-01-V circuit breakers are most commonly used in medium-voltage power applications, within a range of voltage from 2 to 15 kV. They are also suited to two- or three-pole applications, and some models have the ability to disconnect both earth and neutral cables. This makes them particularly useful in premises which use multiple power sources, as they can offer protection against current leakage. Other typical applications include controlling the motor feeders of big machinery, as well as controlling power inputs from large transformers. They can also be used for sectioning to enable smaller transformers to be used in industrial applications.

Working Principle

IEGH66-1-62-6.00-A-01-V circuit breakers are true air-blast circuit breakers, meaning they use air-blast arcs for current interruption. This type of breaker uses two air-blast jets to cool the arc as the current travels between contacts. The jets cool the arc very quickly, meaning the circuit breakers can break quicker than other interrupting devices, making them ideal for power applications which require very fast circuit interruption. The jets are powered by a small portion of the fault current, which causes a high arc velocity that results in a fast interruption of current.

This type of circuit breaker typically works with a spring charging system, which stores the energy needed to close and open the contacts. This makes it reliable and free from external energy sources. It also makes resetting and relaying easier, making it ideal in applications where it is desirable to have a remotely resetting circuit breaker. The IEGH66-1-62-6.00-A-01-V circuit breaker also comes with an integrated current limiting system, allowing for less severe arcs and less damage to equipment.

Advantages

The IEGH66-1-62-6.00-A-01-V has many advantages over other types of circuit breakers. One of these advantages is its fast acting, air-blast current interruption system. This system is more reliable when compared to other types of arc quenching, and is also capable of handling short-circuit currents of up to 20 kA during the most demanding operating conditions. Its reliable disconnecting system prevents any unintentional reconnection, once the circuit breaker has been operated.

The IEGH66-1-62-6.00-A-01-V has also been designed to be user-friendly. The spring-charging system makes it easy to reset and remotely control the circuit breaker. Additionally, the current limiters provide an important safety feature, making it less likely that the equipment will become damaged.

Conclusion

In conclusion, the IEGH66-1-62-6.00-A-01-V circuit breaker is a reliable and efficient device, suitable for a wide range of medium-voltage power applications. Its air-blast arc interruption system provides reliable current interruption, while its spring-charging system and current limiting feature offer improved user safety. This makes the IEGH66-1-62-6.00-A-01-V a popular choice amongst power equipment suppliers.
