IELR1-1-51-20.0-01 Application Field and Working Principle

Circuit breakers are devices that are used to open and close electric circuits in order to protect them from damage and possible shorts. They can also be used to control the amount of current that flows through the circuit. Circuit breakers are usually rated in amps, and come in a variety of sizes and shapes for different applications. This article will discuss the application field and working principle of the IELR1-1-51-20.0-01 circuit breaker.

Application Field

The IELR1-1-51-20.0-01 circuit breaker can be used in commercial, industrial, and residential settings. It is primarily used to prevent overcurrent, providing protection against electric shocks, fires, and other damages. Additionally, the breaker can be used to control the flow of current, allowing it to be used as a switch to turn power on and off.

Working Principle

The IELR1-1-51-20.0-01 circuit breaker works on the principles of electrical resistance and thermal expansion. The circuit breaker is equipped with a bi-metallic element which is heated by the current that passes through it. When the temperature of the bi-metallic element reaches a certain level, the electrical resistance of the bi-metallic element increases, causing the circuit breaker to trip and open the circuit. Once the current is shut off, the bi-metallic element cools down, allowing the electrical resistance to decrease, and the circuit breaker to reset itself.

Conclusion

The IELR1-1-51-20.0-01 circuit breaker is a versatile device that can be used in a variety of commercial, industrial, and residential settings. It works on the principles of electrical resistance and thermal expansion, and is designed to protect electric circuits from overcurrent, electric shock, and fire.
