A circuit breaker, also known as an air circuit breaker, switchgear, or electric switch, is a device used to protect electrical connections from damage caused by excessive current flow. It performs the same function as a fuse, but without the need for replacement after each opening. The 8340-T120-K1T1-ALH0-25A is a type of circuit breaker with specific application fields and a unique working principle.

Application Field

The 8340-T120-K1T1-ALH0-25A circuit breaker is used in a variety of applications. It is suitable for medium and large power networks, such as those found in power stations, distribution networks, industrial plants, and other similar networks. It is also suitable for high-voltage power networks, such as in urban transformation, distributed generation, and any other isolated power transmission plants.

The circuit breaker is designed for use in low-voltage power systems, such as in traction, public lighting, and general industrial protection applications. It is particularly well-suited for use in power networks where the power supply may be subject to sudden changes in load or any other unexpected changes in power inputs. The circuit breaker is also reliable and suitable for use in high-voltage networks where long-distance transmission of electricity is needed.

The 8340-T120-K1T1-ALH0-25A circuit breaker is also an ideal choice for use in any application requiring the prevention of overcurrent and short-circuit. Its design allows it to protect equipment and personnel from any kind of electrical shocks.

Working Principle

The 8340-T120-K1T1-ALH0-25A circuit breaker works on the concept of electromechanical switching. This type of circuit breaker consists of a large number of elements, including copper contacts, a pressure bar, a vacuum interrupter, a mechanical actuator, and a fuse.

When excessive current flow is detected in the circuit, the circuit breaker detects it and triggers the electromechanical switching mechanism. The contacts move towards each other and open the circuit, thereby preventing further current flow.

The mechanism of the circuit breaker also employs an overvoltage protection system, which is designed to protect equipment and personnel against any electric shock caused by a sudden change in the electric current or by any malfunction of the electric system. The overvoltage protection system also protects against the effects of lightning.

Finally, the circuit breaker operates in a closed frame that ensures that all the system components are safe from dust and dirt. This ensures that the contacts on the circuit breaker are kept clean and free from any contamination.

Conclusion

The 8340-T120-K1T1-ALH0-25A circuit breaker is an ideal choice for use in applications where protection against excessive current flow and potential electric shocks is needed. Its electromechanical switching mechanism and its overvoltage protection system ensure that equipment and personnel are safe from any potential hazards. Its design also ensures that it can provide reliable and efficient service over a long period of time.
