Circuit Breakers

UPL1-1REC4-25946-1 Application Field and Working Principle

Circuit Breaker is an important electric system protection device which is widely used in modern industry. In the face of overcurrent, overload, short-circuit, or insulation fault conditions, it can cut off fault and quickly stop the power supply, protect power and personnel safety. UPL1-1REC4-25946-1 they are used to protect circuits, transformers, motors, generators, equipment and people from overloads and short circuits.

UPL1-1REC4-25946-1 is a newly developed advanced breakers, it combines the most advanced current limiting technology, aiming to break and hold the fault current, it also can be used as controlling device coordinately with other components form complex and compound protection system. It is suitable for power supply systems, various industries, power plants, substations, mining enterprises, office, and other places where need the breaking and control.

UPL1-1REC4-25946-1 working principle is that: when the fault current breaks a specific side, the magnetic force generated by the fault current makes the arm of the breaker cut off, the joint connection in between the fault circuit. Then, the contact between the two poles is just broken and the current path is cut off. At the same time, a certain force is generated when the armature moves downward. The armature rotates around the central axis under the power of this force and moves to the opening position due to the arc extinction of the current. The armature is connected to the switch to make the switch open.

UPL1-1REC4-25946-1, as an advanced circuit breaker, is characterized by its accuracy, high breaking capacity, high over current limitation, current interruption capability, low energy consumption, suitable connection form, electromagnetic compatibility, corrosion resistance and mechanical strength and so on. It is used for AC 50Hz, rated voltage 10KV and below the power system, in order to provide protection for short-circuit, leakage, and overload.

The design of UPL1-1REC4-25946-1 circuit breaker is optimized, compact and lightweight, and can be easily installed on the wall or other places. The positioning device of the breaker can easily adjust the distance between the breaker\'s open and close contacts. And its application is very simple, no any complicated settings operations required.

UPL1-1REC4-25946-1, an advanced circuit breaker, not only can provide circuit protection, but also can be used to control the connection and disconnection of the power system in order to achieve the purpose of circuit switching. It has the advantages of high breaking capacity, high current limiting, low power consumption and good accuracy. It can be used for the reliable protection of the power supply circuit and used in a variety of harsh environments.
