Circuit Breakers

Circuit breakers are electrical switching devices used to either protect or isolate an electrical system in the event of an electrical fault or overload. The UPGN66-31142-1 is one such type of circuit breaker. This article will examine the application field and working principles of the UPGN66-31142-1.

Application Field

The UPGN66-31142-1 is a type of molded-case circuit breaker (MCCB) suitable for low-voltage applications. It is designed for use when multiple switchboards must be connected in a series. Its main application is for the protection of transformers, motors, low resistance circuits, and general machinery. Since it is a low-voltage circuit breaker, it is best used in installations with voltages up to 600V.

Working Principle

The UPGN66-31142-1 operates on a three-phase system. It has three poles, each with two or four contacts. When the contacts are engaged, the breaker is closed and the circuit is completed. However, when the contacts become overloaded or there is an electrical fault, the breaker opens and discontinues the flow of electricity. This helps to protect the system against hazardous electrical faults and overloads that could otherwise cause permanent damage.

The UPGN66-31142-1 comes equipped with a special feature that enables it to close without the need for an operator to switch off the breaker manually. This is done with the use of an electronic or mechanical relay, which detects any overload or fault before it occurs. Once the fault is detected, the relay automatically switches off the breaker to prevent further damage.

In addition to the protective functions of the UPGN66-31142-1, it also includes a resistor which limits the current flow in the event of an overload. This ensures that the breaker will not be damaged in the event of a high current fault or overload. This is an important feature that provides added protection and ensures the longevity of the breaker.

Conclusion

The UPGN66-31142-1 is a low-voltage molded-case circuit breaker suitable for use in low-voltage applications. Its main application is for the protection of transformers, motors, low resistance circuits, and general machinery. It operates by making or breaking an electrical circuit in the event of an overload or fault. It also includes a resistor which limits the current flow in the event of an overload to ensure that the breaker is not damaged. This article has examined the application field and working principles of the UPGN66-31142-1.
