Circuit Breakers

UPL111-4119-80 Application Field and Working Principle

Circuit breakers are an essential safety component of any electrical system. They protect both humans and equipment from electrical damage caused by overcurrent, short circuits and other problems. They can be found in homes, businesses and any other places with an electrical system. The UPL111-4119-80 is just one type of circuit breaker. Understanding its application field and working principle is key to staying safe when working with this breaker.The UPL111-4119-80 is an electromagnetic trip unit, meaning it trips off automatically when an electrical fault is detected. It is rated at 10,000 amps, so it can safely handle heavy duty current and is suitable for numerous applications. It is used in a variety of industries, including mining, oil and gas, and heavy machinery.The UPL111-4119-80 works by sensing the current in an electrical circuit. It is designed to respond to faults in the circuit quickly and effectively. If the current becomes too high, the breaker will sense this and trip off the circuit. This will cause the equipment to power down, thus preventing damage.The hot current sensor in the breaker can detect when the temperature of the current is higher than it should be. If the temperature rises, it will trip off the circuit quickly to prevent overheating or a fire.The UPL111-4119-80 also comes equipped with an auxiliary contact which can be used to trip off the circuit at a specific voltage. This could be used to disconnect the main power supply in an emergency, for example.The breaker also has a built-in test and setting facility. This allows for easy testing and calibration of the breaker, ensuring it is working correctly and safely.When installing an UPL111-4119-80 breaker, it is important to make sure the main circuit breaker, which supplies it, has been rated correctly. It is also essential to properly ground the breaker when installing it, as this will ensure it works correctly and safely.Finally, it is important to remember that circuit breakers don’t last forever. It is essential to check them regularly and replace them when they are no longer functioning correctly. This will ensure your electrical system stays safe and reliable.In conclusion, the UPL111-4119-80 is a powerful and reliable circuit breaker. It is suitable for use in a variety of industries and applications. Understanding its working principle and application field is essential for staying safe when working with it. It is also important to remember to check it regularly and replace it when it is no longer functioning correctly.
