Circuit breakers are an essential device in the protection of electrical systems and installations, and UPL11-25445-1 is an example of such a device. It is a Single Phase AC Miniature Circuit Breaker with an adjustable trip curve and international standard conforming design. In this article, we will take a look at the application field and working principle of UPL11-25445-1.

Application Field of UPL11-25445-1

UPL11-25445-1 is designed for single-phase AC systems in the voltage range of 230/400V and frequency range of 50/60 Hz. The device is suitable for a wide variety of residential, commercial, and industrial applications, such as in distribution boards, switchgears, motor control centers, etc. Additionally, the breaker has a load rating of 8A to 40A and can protect electric circuits from overload and short-circuit.

Working Principle of UPL11-25445-1

UPL11-25445-1 employs a thermal-magnetic trip unit to effectively protect the circuit against overload and short-circuit conditions. In normal operation, the devices passes the current to the line and keeps the contacts engaged. The thermal-magnetic unit measures the level of current passing through the breaker and, in the event of an overload, responds by driving a bimetallic element that activates the release system, thus isolating the circuit from the power source. Then, the breaker can be reset by pushing the reset button. The short-circuit protection works similarly, but is provided by an electromagnetic release unit that activates when the current exceeds the specified level.

UPL11-25445-1 also features an adjustable trip curve which allows the user to tailor the device\'s performance according to their individual needs. The trip curve can be adjusted by turning a setting knob located on the side of the breaker. This feature makes the breaker suitable for various types of application and helps to ensure that it can handle the specific requirements of the circuit.

Conclusion

UPL11-25445-1 is a versatile and reliable circuit breaker designed to provide protection for single-phase AC circuits in residential, commercial, and industrial applications. Its adjustable trip curve allows the user to tailor the performance according to their individual needs, making it an ideal solution for all types of applications. Additionally, its thermal-magnetic and electromagnetic protection systems ensure that the circuit is isolated from the power source in the event of an overload or short-circuit, providing reliable and effective protection.
