Circuit breakers are widely used in power distribution systems to protect electrical equipment from overcurrent and short circuit faults. UPG6-23503-6 is a type of circuit breaker that is used for residential, commercial and industrial applications. It is designed to disconnect and protect a circuit in the event of overload. In this article, we will discuss the application field and working principle of UPG6-23503-6.

Application Field

UPG6-23503-6 circuit breakers are suitable for residential, commercial and industrial use. They are designed to provide protection for various medium and high voltage circuits. The circuit breakers are typically installed in panel-mounted locations and can be used for up to 1000 V ac circuits. They are also designed to withstand current surges of up to 20,000 amps.

The UPG6-23503-6 circuit breaker is designed for a wide range of applications such as air-conditioning, lighting, heating, ventilation, elevator control, medical equipment, railway applications and many more. Additionally, they can be used in industrial applications such as power metering systems, switch gear, motor control centers and motor control systems.

Working Principle

The UPG6-23503-6 circuit breaker works by using a bimetallic strip which is composed of two different metals. When the current flowing through the circuit exceeds the rated value, the strip is heated up due to the Joule effect and it expands. This expansion triggers a switch mechanism that disconnects the circuit and breaks the flow of current.

The bimetallic strip is equipped with a calibrated thermostat that is calibrated to detect any increase in current flows and disconnects the circuit if the current exceeds the rated value. This ensures the circuit is not damaged by an overloaded or short-circuit fault.

The UPG6-23503-6 circuit breaker also requires a circuit integrity test every two years in order to ensure it is functioning correctly. This is done using a current meter which measures the operating current of the circuit and the terminal voltage.

Once the integrity of the circuit breaker has been verified, it is ready to be used for medium and high voltage applications. The circuit breaker will then protect the circuit from any overload or short-circuit faults that could cause damage to the electrical equipment.

In conclusion, UPG6-23503-6 circuit breakers are a practical solution for many residential, commercial and industrial applications. They are designed to provide protection for various medium and high voltage circuits by automatically disconnecting the circuit in the event of an overload. The circuit also requires a circuit integrity test every two years to ensure it is working correctly.
