Circuit Breakers: UPGH22-21148-2 Application Field and Working Principle

Circuit breakers are important safety devices in many industries. These devices serve to protect both electrical equipment and personnel from harm in the event of a power surge or an overload of a particular circuit’s capacity. UPGH22-21148-2 circuit breakers are among the most popular on the market. This article looks at the application fields and working principle of these devices.

Application Fields

UPGH22-21148-2 circuit breakers are designed for a wide range of applications. For instance, they are suitable for use in industrial control panels, as well as for protection of individual motors or other electrical devices. The device’s ratings should be taken into consideration in order to ensure the correct break capacity and voltage. It is important to select a circuit breaker which meets the application’s specific requirements.UPGH22-21148-2 circuit breakers can also be used for educational purposes. Electrical engineering students can use the devices to gain hands-on experience with circuit protection. Moreover, the devices are often used in training seminars which provide information on electrical safety and proper circuit breaker selection.

Working Principle

A UPGH22-21148-2 circuit breaker works on the principle of bridging the gap between two conductive surfaces. A circuit breaker typically consists of an electromechanical device, which is triggered by an overload in the system. The mechanism then opens the circuit and interrupts the electrical flow. In order to reset the device, the system must be switched off and then manually reset with its handle.The UPGH22-21148-2 circuit breakers operate on a thermal-magnetic principle. This involves the combination of two different technologies, namely, thermal sensing and magnetic field sensing. In the thermal-magnetic sensing mode, a bimetallic strip will sense the temperature of the circuit and its resistance. If the temperature or resistance increases beyond the pre-set parameters, the device will trip and open the circuit.In addition, the UPGH22-21148-2 circuit breakers also utilize a time-delay feature. This allows for a brief period of delay before the circuit breaker trips. This feature helps to protect against nuisance tripping, as a momentary power surge or high inrush current will be tolerated for a limited time period.

Conclusion

UPGH22-21148-2 circuit breakers are well suited for a variety of applications. These versatile devices offer protection against power surges and overloads, as well as provide additional safety features. The devices are designed to work on the principle of bridging the gap between two conductive surfaces, which is achieved by the combination of thermal and magnetic sensing. Moreover, the addition of a time-delay feature allows for a brief period of delay before the breaker trips.
