Circuit Breakers are critical components used to protect both electrical and electronic equipment and networks from damage due to overvoltage, excessive current, or faulty wiring. When an unwanted electrical or electronic phenomenon occurs, the circuit breaker will automatically disconnect the circuit to protect against any further damage to the equipment or network. The UPG112-4380-12 is an example of a circuit breaker, and this article will discuss its application field and working principle.

Application Field

The UPG112-4380-12 circuit breaker can be used in a number of different applications, including residential, commercial and industrial applications. It is particularly well suited for medium- to high-voltage applications, because it is designed to trip quickly and reliably when an overvoltage, excessive current, or other fault occurs. Additionally, it is UL rated for permanent installation, so it is a reliable and safe choice for protecting vital equipment and networks from damage. The UPG112-4380-12 is also very easy to install with standard tools and equipment, so it is an ideal solution for any application where circuit protection is needed.

Working Principle

The UPG112-4380-12 circuit breaker works on the principle of thermal-magnetic effect. A thermal-magnetic circuit breaker works by using a bimetallic strip and a magnetic coil to sense and respond to overcurrents. The strip itself is made of two different metals that have different expansion coefficients when heated. When the current flowing through the circuit reaches a certain level, it creates heat in the bimetallic strip. As the strip heats up, it bends due to the difference in the expansion coefficients of the two metals. This bends the bimetallic strip enough to activate the built-in magnetic coil, which trips the circuit and breaks the circuit, protecting the equipment from further damage.

Once the circuit has been tripped, the bimetallic strip will cool down, and the strip will return to its initial position. This allows the circuit to be reset and the circuit breaker to be reset. The UPG112-4380-12 circuit breaker is designed to rapidly trip and reset the circuit in the event of an overcurrent, or other fault. This ensures that electrical and electronic equipment and networks are protected from any further damage.

Conclusion

The UPG112-4380-12 circuit breaker is an ideal choice for medium- to high-voltage applications. It is reliable, easy to install, and UL rated for permanent installation. Additionally, it works on the principle of thermal-magnetic effect, using a bimetallic strip and magnetic coil to detect and interrupt overcurrents and other faults. This ensures that vital equipment and networks are protected from further damage. By choosing the UPG112-4380-12 circuit breaker, users can have peace of mind, knowing that their equipment is protected.
