Circuit Breakers are essential components in electricity related circuits and systems. The UPG40-1REC4-29347-1 is an important representative commonly used in modern applications. By understanding the application field and working principle of the UPG40-1REC4-29347-1, its proper usage in various electric systems can be better realized.

UPG40-1REC4-29347-1 Application Field

The UPG40-1REC4-29347-1 is a miniature vacuum circuit breaker with rated working voltage 690V/50Hz, the breaking capacity of 25kA, short time durable current 40kA, and 380V auxiliary circuit. It is designed for commercial or industrial use, such as generator setting, distribution network, and substation,ect. Moreover, it can be applied in places such as power station, manufacturing industry,mining, and oil production area, ect. This type of circuit breaker offers an extremely low noise level and cooling rate, and it is also easy to maintain and offers a long service life.

UPG40-1REC4-29347-1 Working Principle

The UPG40-1REC4-29347-1 consists of three parts, including its over voltage protector, contactor relay, and vacuum interrupter. This type of circuit breaker works by firstly using the contactor relay to detect whether a fault has occurred in the system. When a fault occurs, the contactor relay will activate the over voltage protector to stop the current flow. After that, the vacuum interrupter will take over the breaking process and disconnect the power. This process of breaking the circuit is known as “vacuum breaking”, and its main advantage is that it can constantly de-energize the system and reduce the shock wave generated from the arc-over.

Once the system is de-energized, the contactor relay will close again, and the interrupter will be re-energized. At this point, the over voltage protector can be disabled and the power can be reset. Furthermore, the contactor relay of the UPG40-1REC4-29347-1 comes with a reset button, so that users can manually reset the circuit if they need to.

Conclusion

The UPG40-1REC4-29347-1 is a reliable and high-quality circuit breaker that comes with a wide range of applications and an effective working principle. With its low noise level and cooling rate, it is perfect for commercial or industrial use. Moreover, because it is easy to maintain and offers a long service life, it is an ideal choice for facilities that require frequent power outages or are exposed to frequent electrical surges.
