Circuit breakers play a broad and significant role in the electrical world. They are responsible for protecting components from voltage and current overloads, as well as short circuits. One such example is the IELZX11-1-62-20.0-03-V circuit breaker. In this article, we will discuss the application field and working principle of this circuit breaker.

IELZX11-1-62-20.0-03-V Application Field

The IELZX11-1-62-20.0-03-V circuit breaker is mostly used in residential designs because it is a low-voltage circuit breaker. Primarily, it serves as a device that automatically opens when a fault is present in the circuit. It is designed to prevent damage to people, equipment, and property in case of an overload or short circuit. It can be further used for controlling other electrical devices such as motors, lighting systems, and even air conditioners.

Some of the benefits of using this circuit breaker are: it has three-phase motor protection features, it has an overload and thermal protection protection feature, and it is also equipped with a shunt trip and an external RCCB feature.

IELZX11-1-62-20.0-03-V Working Principle

The working principle of the IELZX11-1-62-20.0-03-V circuit breaker is relatively simple. It works by monitoring the current flowing through the circuit and comparing it to a preset limit. If the limit is exceeded, the circuit breaker will automatically disconnect the circuit, thus preventing a possible overload or short circuit.

The circuit breaker contains an internal device known as a bimetallic element. This element is composed of two metals with different thermal properties. When current passes through the circuit, the element will heat up. Once a preset temperature is reached, the bimetallic element will bend and open the contacts, thus interrupting the current flow.

The IELZX11-1-62-20.0-03-V circuit breaker also has an overcurrent protection feature. This feature helps to protect against overcurrents by disconnecting the circuit when an overload or short circuit is present. The circuit breaker also has an auxiliary contact which is responsible for providing a signal to the user in the event of a fault.

Finally, the IELZX11-1-62-20.0-03-V circuit breaker also has a shunt trip feature. This feature can be activated manually, or it can be used in conjunction with a remote emergency power control system to open the circuit in case of an emergency.

Conclusion

The IELZX11-1-62-20.0-03-V is a versatile, multipurpose circuit breaker with a variety of features. Primarily, it is used for residential applications and serves to protect components from voltage and current overloads, as well as short circuits. Its working principle is based on the bimetallic element which heats up when current passes through the circuit, thus tripping the contacts. It also has an overcurrent protection, an auxiliary contact, and a shunt trip feature for added protection.
