Circuit Breakers are electrical safety devices designed to protect electrical circuits from the potentially damaging effects caused by overloads, short circuits, and other faults. UPL5-8626-1 is one of the high performance Circuit Breakers. This article will discuss the application field and working principle of UPL5-8626-1.

Application Field

UPL5-8626-1 can be used in various application fields, such as low voltage circuit breaker, industrial control, automatic equipment, power source equipment, HV motor control, remote control, etc. It can be an essential part of modern industry and commerce system, helping to prevent accidents and protect equipment against improper operation. UPL5-8626-1 is designed to offer full motor protection from thermal, mechanical, electrical and arc faults.

Working Principle

The working principle of UPL5-8626-1 is based on thermal-magnetic release technology. It is composed of a thermomagnetic release, an arc chute and trigger kit, springs, contacts, trip-free mechanism, auxiliary contacts, etc. When the current is above the rated current, the thermal-magnetic release may be activated, causing UPL5-8626-1 to trip. This process happens in a very short time, ensuring that the protective circuit breaker can protect itself and the pertinent device or system.

When the overcurrent occurs, the overcurrent heat takes certain time to heat up the bimetallic combination. When the temperature of the bi-metallic combines reaches the rated temperature, the bi-metal combination will deflect and the necessary levers just turn the trip-free mechanism. This mechanism provides sure and reliable tripping of the breaker contacts. Then, the arc chute separates the contacts from each other which moves the interrupting contacts to the opening position, thus isolating the current on the circuit. The auxiliary contact is used to send signals to an external equipment so that the alarm or control system may be triggered. After the power is cut off, the mechanism of UPL5-8626-1 will reset automatically.

Conclusion

In conclusion, UPL5-8626-1 is an advanced Circuit Breaker. It is widely used in various industries thanks to its safety features and thermal-magnetic release technology. Its working principle is based on the thermal-magnetic release, which can ensure the protection of pertinent equipment and the electric circuit. Understanding the application field and working principle of the Circuit Breaker can help us make better use of the product and prevent accidents.
