Circuit breakers are one of the most important safety components for electric power systems, and LELK1-1REC4-29475-2 is among the top tier of such devices. This article will discuss the various applications and working principles of LELK1-1REC4-29475-2 circuit breakers.

Applications of LELK1-1REC4-29475-2 Circuit Breakers

Circuit breakers are commonly used in residential, commercial, and industrial applications. Specifically, LELK1-1REC4-29475-2 circuit breakers can be used for high voltage and direct current (DC) applications, such as wind turbines and high voltage solar installations. In addition, it is also suitable for medium and low voltage applications, such as switchgear and substations. In general, no matter the application, LELK1-1REC4-29475-2 circuit breakers can provide reliable, efficient, and safe protection for the related electrical systems.

Working Principle of LELK1-1REC4-29475-2 Circuit Breakers

LELK1-1REC4-29475-2 circuit breakers are designed with an air interrupter that works to open, or close, an electrical circuit when the current flow exceeds a safe level. The air interrupter is a column of air, to which an arc is formed when the circuit is interrupted. At the same time, an arrester is present to transform the material close to the open arc, thus allowing the current to disperse while evaporation of contacts takes place. This process limits the spread of the arc and its associated risk of electric shock.

The air interrupters are also fitted with mechanical operation that reset the circuit breaker when necessary. This is made possible through its surface gap arc extinguishing chamber, which is equipped with copper electrodes and copper-tungsten contacts. It also contains a pressure-sensitive spring-loaded mechanism which accumulates kinetic energy as the operating lever is moved into the closed position. This is then stored until it is triggered to break an open arc.

Other Features of LELK1-1REC4-29475-2 Circuit Breakers

LELK1-1REC4-29475-2 circuit breakers includes additional features, such as over-current and differential protection. This helps to prevent overvoltage and overheating by automatically interrupting the circuit when necessary. This helps to prevent damage to the system from excessive power or current. Additionally, it has a manometer to measure the pressure of the air interrupter and a speed control to adjust the speed of the reset. This helps to ensure that the circuit breaks for the correct amount of time.

Conclusion

LELK1-1REC4-29475-2 circuit breakers provide reliable, efficient, and safe protection for different electrical systems. This makes them a perfect choice for high, medium, and low voltage applications. They include a powerful air interrupter with an arrester and copper-tungsten contacts, which together form an insulated arc to prevent electric shock. Other features include over-current protection, differential protection, a manometer, and a speed control.
