Circuit Breakers

Circuit Breakers (CBs) provide important protection for your electrical system by interrupting the electrical current flow when a fault is detected. They can be used in many applications, such as residential and commercial buildings, industrial facilities, and transportation systems. The IAGN66-22437-2 is a type of circuit breaker that is widely used.

IAGN66-22437-2 Application Field

The IAGN66-22437-2 is a miniature circuit breaker (MCB) designed for low-voltage applications. This type of circuit breaker is commonly used in domestic applications, like fuse boxes, where it is tasked with protecting against short circuits and other possible electrical faults. It is suitable for currents up to 25A at a rated voltage of 230/400V AC (Alternating Current). It is a two-pole breaker, with an insulation voltage rating of up to 500V. This makes it suitable for a wide range of applications, from residential and commercial to industrial.

IAGN66-22437-2 Working Principle

The IAGN66-22437-2 circuit breaker works according to an overcurrent principle. This means that when an overload or short circuit is detected, the breaker quickly trips to disconnect the electrical circuit. The breaker works in two stages; firstly, it rapidly trips the power on detecting a fault, and then it gradually reduces the trip time if the fault persists. This both reduces the risk of fire and allows the user to reset the breaker after the fault has been cleared.

The IAGN66-22437-2 circuit breaker has a thermal-magnetic mechanism, which is composed of two elements: a bimetal element and a magnetic element. The bimetal element is made up of two dissimilar metals, and when heated, it moves at a certain speed and trips the power. The thermal element is sensitive to current overloads, and trips the power when the current exceeds the rated value. The magnetic element is sensitive to short circuits, and trips the power when the electric current drastically increases.

The IAGN66-22437-2 circuit breaker is designed with a manual test/reset button, which can be used to safely test the trip currents of the circuit breaker. This allows the user to check the condition of the breaker and verify that it is working correctly.

Conclusion

The IAGN66-22437-2 is an overload and short circuit protection device that is widely used for low-voltage applications. It has a thermal-magnetic mechanism which works to quickly trip the power in the case of an overload or short circuit. It is also equipped with a manual test/reset button, allowing the user to test the trip currents of the circuit breaker. This makes it an ideal choice for protecting residential and commercial buildings, industrial facilities, and transportation systems.
