Circuit Breakers are essential components when it comes to protecting electrical circuitry. They are used to prevent the flow of power when there are fault conditions or overloads. There are many kinds of circuit breakers packed with different features. One such kind is the IUGN 66-39073-2. While IUGN 66-39073-2 circuit breakers are often used in a variety of applications, in this article we will take a look at its general application field and working principle.

Application Field of IUGN 66-39073-2

IUGN 66-39073-2 circuit breakers are primarily used in electromagnetic motor control, instrumentation control market, emergency lighting, long time hold time with no failure. It is mainly used in control device applications such as industrial machinery protection, motor controllers, relays, contactors, and so on. It is also widely employed in AC-DC electrical equipment such as drives, electromechanical meters, and microprocessor-based instruments.

IUGN 66-39073-2 circuit breakers possess various process control functions which make them ideal for high voltage applications. These functions include current limit, over voltage protection, under voltage protection, short circuit protection, and surge protection. Moreover, it has been designed with current carrying capabilities up to 100A. Its minimum interrupting capacity is 4KA, making it suitable for many applications. Additionally, the IUGN 66-39073-2 circuit breaker also comes with built in carrying and tripping mechanisms to ensure reliable performance.

Working Principle of IUGN 66-39073-2

The working principle of IUGN 66-39073-2 circuit breaker is quite simple. It is a thermal-magnetic circuit breaker with a trip risk indicator. When the current flowing through the device exceeds a certain level, the internal components of the circuit breaker heat up, causing the trip element to move. This trips the breaker at the desired current level.

Moreover, the trip element also works in conjunction with the tripping mechanism to ensure that the switch quickly breaks the circuit when an over current situation occurs. Furthermore, the trip risk indicator allows users to see at a glance if the breaker is open or closed. This helps to ensure the safety of personnel in industrial environments.

In conclusion, IUGN 66-39073-2 circuit breakers are widely used in a variety of applications due to their robust features, reliable performance, and safety features. In addition, the thermal-magnetic working principle helps to protect the device and the circuit from damage when an over current situation occurs. Therefore, IUGN 66-39073-2 circuit breakers are a very reliable and highly efficient choice for industrial circuit breaker protection.
