Circuit breakers are essential elements of any electrical system, providing basic protection and circuit interruption when a fault is detected. IMG1-30813-1 is one type of circuit breaker and this article will discuss its application field and working principle.

IMG1-30813-1 is mainly used for medium voltage air insulation switchgear, being installed in the vacuum circuit breaker enclosure. This type of breakers is specifically designed to be used in the most severe conditions, providing reliable performance in the most difficult environments with high levels of auto-extinction and contact erosion.

When the circuit breaker is under normal working conditions, its contacts stay firmly closed, so that the current flows through them. However, when the circuit breaker detects a fault, it will automatically detect it and open its contacts to interrupt the flow of current. This prevents damage to the equipment and protects personnel or customers from harm.

In order to open the contacts, the circuit breaker relies on an electromagnetic core. This core is connected to a solenoid, which produces a magnetic field strong enough to open the contacts, which allows the current to stop flowing without any further damage.

Once the fault is over, the current will again flow through the circuit breaker. The magnetic field created by the solenoid fades away, allowing the contacts to close again, and the cycle will then repeat. This process works in a fraction of a second, ensuring that no personnel or customers are in danger.

When compared to other types of circuit breakers, such as AC breakers or DC breakers, IMG1-30813-1 offers superior performance and reliability. This is mainly due to its advanced contact design, which allows it to perform better with higher levels of contact erosion. Additionally, its design makes it suitable for harsh environments, where it can safely and quickly break an overcurrent.

In conclusion, IMG1-30813-1 is a type of circuit breaker mainly used for medium voltage air insulation switchgear. It relies on an electromagnetic core, which when activated by a solenoid, opens the contacts to interrupt the flow of current. This type of circuit breaker offers superior performance and reliability compared to other types, which makes it suitable for the most difficult environments.
