Circuit Breakers

A circuit breaker is an important electrical device that is designed to protect electrical circuits from any damage due to an overload or a short circuit. It automatically disconnects an electrical circuit when it is overloaded or when a short circuit occurs, thus preventing any serious damage to the electrical equipment or even to the individuals using the electrical circuit. The R21-62-20.0A-B06EV is a type of circuit breaker that is used for a wide variety of applications. In this article, the application field and working principle of the R21-62-20.0A-B06EV circuit breaker will be discussed.

Application Field

The R21-62-20.0A-B06EV circuit breaker is typically used in industrial and commercial applications that require high current rating and high voltage breakers. It is often used in large electrical systems, such as power plants and substations, as well as in commercial applications, such as industrial factories and other large business systems.

In addition to industrial and commercial applications, the R21-62-20.0A-B06EV circuit breaker can also be used in residential applications. It is often used to protect circuits in homes, offices, and other living spaces from surges and overloads. It is also commonly used in vacation homes that may not be equipped with a high-capacity surge protector.

Working Principle

The R21-62-20.0A-B06EV circuit breaker operates on a thermal-magnetic principle. This means that it has two components: a thermal element and a magnetic element. The thermal element measures the temperature of the electrical circuit, while the magnetic element senses any current overloads. When the temperature of the circuit or the current overload reaches the predetermined level, the circuit breaker trips and turns off the power supply.

When a circuit breaker trips, the thermal element cools, and the magnetic element deactivates, thus stopping the power flow to the circuit. The thermal element is also capable of resetting itself when the temperature of the circuit falls back below the predetermined level, hence allowing power to be supplied to the circuit again.

Conclusion

The R21-62-20.0A-B06EV circuit breaker is a type of circuit breaker that is designed for a variety of applications, from residential to industrial and commercial applications. It operates on a thermal-magnetic principle and is equipped with a thermal and magnetic elements. When an overload or short circuit occurs, the circuit breaker trips and halts power supply, and when the temperature of the circuit or the current overload returns to normal levels, the circuit breaker can be reset and the power supply can return.
