Circuit Breakers are essential pieces of electronics hardware used in many aspects of our lives, from home appliances to industrial manufacturing processes. The UPL43-203-20 is a specific model of circuit breaker used in a wide range of industrial applications. In this article, we will look into detail at the UPL43-203-20 and what its field of application and working principles are.

Circuit Breaker Overview

A circuit breaker is a device that can open or close a circuit by interrupting the current flow. Circuit breakers are used in many different types of electrical systems to prevent electric shock during the operation of the system. By using circuit breakers, electrical equipment can be kept safe. Circuit breakers come in various sizes and models, with each model being designed for different applications.

UPL43-203-20 is a two-pole thermal-magnetic circuit breaker used in various industrial applications. This model is designed to protect electrical equipment and circuits from short circuits, overloads, over-voltages, and ground faults. Depending on the type of circuit breaker, it can be operated manually or automatically, and it will also detect when a fault has occurred and open the circuit to prevent damage to the electric equipment.

UPL43-203-20 Application Field and Working Principle

The UPL43-203-20 is a two-pole thermal-magnetic circuit breaker with a trip curve of B. It is designed for various industrial applications, such as electric motors, elevators, industrial process control, lighting systems, and other loads that require reliable protection. This circuit breaker is suitable for use in industrial circuits with AC voltage of up to 240V in Single-phase and 415V in Three-phase.

The working principle of the UPL43-203-20 is simple yet effective. This model uses both thermal and magnetic tripping to prevent electric shocks and overloads. The thermal element is designed to detect the increase in temperature caused by an overload and trip the circuit breaker in the time specified. The magnetic element is designed to detect the high current caused by a short circuit and trips the circuit breaker in the time specified. The trip time is adjustable depending on the type and size of the circuit.

Apart from the thermal and magnetic tripping, the UPL43-203-20 also has features such as an adjustable short-time delay, voltage selector, and an adjustable long-time delay. This allows for greater flexibility when configuring the circuit breaker. On top of that, this model also has a manual reset button and a visual indication of its power status.

Conclusion

The UPL43-203-20 is a two-pole thermal-magnetic circuit breaker designed specifically for industrial applications. This model has adjustable short-time and long-time delays as well as a voltage selector that allow you to configure the circuit breaker for a wide range of applications. The thermal and magnetic tripping of the circuit breaker helps ensure the safety of electrical equipment and circuits. With its many features, the UPL43-203-20 is an ideal circuit breaker for industrial and commercial applications.
