Circuit Breakers: 2907690 Application Field and Working Principle

Circuit breakers are highly integral parts of various residential and commercial electrical systems, as they are responsible for preventing the major damages of electrical systems, caused by any electrical failure. A major example of such failure would be the spike of high voltage. The 3077690 circuit breaker is specially designed for use in such situations. In this article, we\'ll discuss the application field and working principle of the 2907690 circuit breaker.

Application Field of 2907690 Circuit Breaker

The 2907690 circuit breaker is specifically designed to detect a wide range of overvoltage conditions. It is mostly used in commercial and residential buildings, where it is installed near the main electrical panel and functions as the main circuit breaker. This type of circuit breaker is also used in the HVAC system of the buildings, where it ensures the protection of the compressors, condensers and fan motor. Furthermore, the 2907690 circuit breaker is also used in lighting circuits, so as to avoid any damage due to the high voltage.

Working Principle of 2907690 Circuit Breaker

The main purpose of the 2907690 circuit breaker is to detect any overvoltage conditions, and de-energize the system immediately in order to prevent any major damage. The working of such a circuit breaker is based on the thermal magnetic principle, where it is equipped with two elements, i.e. the thermal element and the magnetic element. The thermal element has a bimetallic strip which is designed to react to an increase in temperatures. On the other hand, the magnetic element is made up of a solenoid with a built-in coil, which helps in sensing any abnormally high currents, and setting off the break.When the circuit is inserted, the current flowing through it gets divided and a part of it is sent to the thermal element. As the current passes through the bimetallic strip, it causes a rise in the temperature, thus making the two metals of the strip apart and ultimately tripping the circuit breaker. Similarly, the magnetic element reacts to any abnormally high currents, thus responding to a fault trip condition and protecting the circuit from any major electrical damage. It should be noted that the working of the 2907690 circuit breaker is illustrated on the basis that it is equipped with a thermal magnetic combination and not solely with a magnetic element.

Conclusion

The 2907690 circuit breaker is usually used in residential and commercial electrical systems, where it is responsible for controlling current flow and protecting the electrical system from any major electrical damages, due to overvoltage conditions. The working of the 2907690 circuit breaker is based on thermal magnetic principle, whereby it is equipped with both the thermal and the magnetic elements. The thermal element is responsible for reacting to a rise in temperature, while the magnetic element is used for sensing any abnormally high current and thus preventing any major damage.
