Introduction of Circuit Breakers

Circuit breakers are electrical devices used to protect electrical systems from overloads or short circuits that could cause damage by overheating and/or excessive current. They are used in a wide range of applications and industries, such as in homes, factories, and power grids. The most common types of circuit breakers are air circuit breakers, oil circuit breakers, and vacuum circuit breakers.

IELK2-30458-1 Application Field and Working Principle

IELK2-30458-1 is a type of circuit breaker designed for use in medium-voltage power systems. It is a sealed dry type circuit breaker with a vacuum interrupter design. It has an operating voltage range of 690V to 33KV, and a current rating of up to 25KA.

The IELK2-30458-1 circuit breaker consists of a fixed and moving contact that is connected to the breaker\'s interrupter. The interrupter is a vacuum tube filled with a pressurized gas, such as air or an inert gas. When an overload or a short circuit occurs, the contacts separate, interrupting the flow of current and preventing an overload.

The IELK2-30458-1 circuit breaker has several safety features designed to protect the system from overcurrent. It is equipped with built-in surge protective devices, magnetically operated over-current trip units, and pressure operated surge arresters. These mechanisms are designed to protect the system from overcurrents and prevent excessive damage or fire.

The IELK2-30458-1 circuit breaker is typically used in medium-voltage power systems, such as in factories, industrial complexes, and power grids. Its compact size and high reliability make it ideal for these applications. The breaker is also suitable for use in hazardous areas, thanks to its non-incendive and arc-resistant designs.

Conclusion

The IELK2-30458-1 circuit breaker is a reliable and safe type of circuit breaker designed for use in medium-voltage power systems. It is equipped with multiple safety features, including built-in surge protective devices, magnetically operated over-current trip units, and pressure operated surge arresters. The IELK2-30458-1 circuit breaker is highly reliable and suitable for a wide range of applications, including hazardous areas.
