Introduction

UPG1-34843-2 circuit breakers are essential components in the electrical power distribution systems, where they are used to protect substations, switchgears, and other electrical devices from damage due to short circuits and overloads. They are designed to meet the need of commercial, industrial, and utility applications, providing reliable protection and switching of various loads.

Application Field

UPG1-34843-2’s applications can be divided into two fields. Firstly, it can be deployed to supply electricity to residential or commercial customers in medium-voltage arcs. These devices are molded case type Insulated Case Circuit Breakers (ICCB), providing good breaker stability and guarantee to prevent arc flash event which might damage people or property. Secondly, UPG1-34843-2 can be used in low-voltage systems such as distribution panel boards, switchboard, motor control centers, building systems, or other special distribution systems. It is designed to be a multi-functional switch control system used to supervise and switch any number of DC or AC circuits with each other. The application range of this product can be extended further with different optional accessories such as circuit monitor modules, diagnostic signaling modules, etc.

Working Principle

The working principle of UPG1-34843-2 breakout is straightforward. Inside the break is an electromechanical trip unit, which is driven by a spring-loaded mechanism powered by electricity. When the trip unit detects a short circuit or overload, it disconnects the circuit to prevent damage. The electromagnetic trip unit is designed to test for persistent over current conditions, so as to decide whether to trip or maintain the breaker.

UPG1-34843-2 circuit breaker is designed with auxiliary contacts which closes immediately when the breaker trips. The auxiliary contacts are commonly used while installing the circuit breaker to activate an alarm indicating that a short circuit or overload had occurred in the circuit. It is also used to reset the circuit breaker to restore power to the circuit after the fault has been eliminated.

Conclusion

In conclusion, UPG1-34843-2 circuit breakers are versatile components that have wide application in both medium-voltage and low-voltage systems. It is designed for reliable protection against short circuits and overloads, and is equipped with auxiliary contact for alarm indication when such events occur. It is easy to install, and provides a cost-effective solution for electrical protection, making it an invaluable component in any electrical power system.
