Circuit Breakers refer to electrical components that are able to quickly open or close electrical circuits in order to avoid short circuits and overloading of circuits. The UPL11-6422-1 is one such example. As a part of the schneider Universal range of circuit breakers series, this breaker has certain unique characteristics and advantages that make it suitable for a number of applications.

UPL11-6422-1 application field

The UPL11-6422-1 is a multi-pole circuit breaker with a rated voltage of 500V AC and current ratings ranging from 0.02A to 6A. It is typically used for the protection of motors, lighting, transformers, and other electrical equipment from overcurrents as well as short-circuiting. It can also be used for the purpose of switching on or off the equipment connected to it, making it a valuable asset for a number of industrial and commercial applications. It is also highly reliable as it has a Double Action Trip Function, which means that when the upper and lower operating limit of the circuit breaker is exceeded, the circuit breaker is able to automatically disrupt the circuit, thus preventing an overload or possible electrical fire.

UPL11-6422-1 Working principle

The UPL11-6422-1 works on the principle of thermal-magnetic tripping, which means that it employs both a thermal release and a magnetic release component in order to achieve the desired protection and functionality. The thermal release is made up of a bimetallic strip that is responsible for the detection of increased temperatures as a result of current overloads or short circuits in the system. When the temperature reaches a certain limit, it triggers a thermal trip, causing the bimetallic strip to bend and cut off the power supply. On the other hand, the magnetic release is responsible for detecting excessive current in the system. This is done with the help of an electromagnetic coil that is connected to the circuit breaker. As the current increases, the coil charges up and when the preset current limit is exceeded, the coil triggers the magnetic release, causing the circuit breaker to trip.

The UPL11-6422-1 also has several added features along with its standard tripping mechanism. For instance, it can be equipped with an external operator that can be used to manually open or close the circuit breaker without having to open the device. Additionally, it also has an integrated mechanical lock that prevents any unintended switching of the circuit breaker. All these features make the UPL11-6422-1 a reliable and suitable choice for a wide range of circuit protection and switching applications.

Conclusion

The UPL11-6422-1 is a multi-pole circuit breaker with a rated voltage of 500V AC and current ratings ranging from 0.02A to 6A. It is typically used for the protection of motors, lighting, transformers, and other electrical equipment from overcurrents as well as short-circuiting. It works on the Thermal-Magnetic Tripping principle and can be equipped with an external operator and an integrated mechanical lock for added convenience. Due to its multiple features, it is considered to be one of the most reliable circuit breakers on the market and is suitable for a wide range of circuit protection and switching applications.
