Introduction of 3120-F314-P7T1-W12DY3-20A Circuit Breaker

3120-F314-P7T1-W12DY3-20A circuit breaker is a device used to protect electrical supplies from overloads and short circuits, which is widely applied in power engineering. It is consisted of metal arc quenching enclosure, bimetal temperature sensor, contact system, arc extinguisher, and etc.

Application Field

3120-F314-P7T1-W12DY3-20A circuit breaker is applied in many places, such as home, industrial production and office. In home, it is mainly used in electrical systems in the kitchen, basement, laundry room and so on. As for industrial applications, it is mainly used in factories, substations and machine tools. In office application, 3120-F314-P7T1-W12DY3-20A circuit breaker is used in places that operate high-power electric machinery, such as medical rooms, electric elevator and so on.

Working Principle

The working principle of 3120-F314-P7T1-W12DY3-20A circuit breaker is simple. It relies on contact systems to control and open and close the electric circuit. When there are overloads or short circuits, the bimetal temperature sensor will detect the sudden increase of temperature of the electric circuit and send a signal to the contact system. The switch system will then combine with the arc extinguisher to quickly break the electric circuit. After the overloads or short circuits are removed, the contact system will reset the system and reconnect the circuit.

Advantages

3120-F314-P7T1-W12DY3-20A circuit breaker has many advantages. Firstly, it has strong protective barrier, which is able to effectively protect the electric supplies from overloads and short circuits. Secondly, it has good motor protection performance, which is able to accurately detect motor overloads. Thirdly, it has the ability to automatically disconnect when circuit overcurrent is detected or when the insulation of the circuit becomes too low. Fourthly, compared with fuses, it has a longer service life and is able to withstand more electrical current than fuses.

Conclusion

3120-F314-P7T1-W12DY3-20A circuit breaker is a device used to protect electrical supplies from overloads and short circuits. It is widely applied in home, industrial and office applications. The working principle of the circuit breaker is simple. It has many advantages, such as strong protection, good motor protection performance and long service life. Therefore, it is an ideal choice for protecting electrical supplies.
