Circuit Breakers

UPG11-1REC2-5952-1 Application Field and Working Principle

Circuit breakers are essential to ensure the safety of any electrical device or system. Circuit breakers are protective devices designed to open and close the circuit at a certain rating. Circuit breakers are available in different ratings such as low-voltage, medium-voltage, and high-voltage. In order to protect an electrical device or system from dangerous overcurrents such as short-circuiting, the UPG11-1REC2-5952-1 is a form of medium-voltage circuit breaker with an equivalent operating voltage of 1150 V with a rated current of 250 A. The breaker is tested to a rated voltage of 12kV and a rated frequency of 25kHz.

The UPG11-1REC2-5952-1 circuit breaker is mainly used for short-circuit protection on power distribution lines with a nominal voltage of 1000 V or less. It acts as the main switch for on/off switching between the power and load circuit. Moreover, it plays an important role in the protection of the electrical circuits against overloads and short circuits. The UPG11-1REC2-5952-1 can be applied to sources, transmitters, and all kinds of electrical equipment.

This circuit breaker is built with a relatively simple design that includes three components: a tripping element, an action element, and a contact system. The tripping element, which is the main part of the device, is responsible for the tripping or opening of the device in case of a short circuit or overcurrent. The action element is responsible for controlling the opening or closing speed of the device according to the current flowing through it. Lastly, the contact system is used to switch on/off the device as well as to interrupt the circuit.

The working principle of the UPG11-1REC2-5952-1 circuit breaker is based on the heat generated due to the flow of current in the device. The heat generated is measured within the device, and when the temperature reaches a certain limit, the circuit breaker trips and opens the circuit. This helps to prevent any further damage or fire hazards due to excessive current.

In conclusion, the UPG11-1REC2-5952-1 circuit breaker is a form of medium-voltage breaker that is mainly used for short-circuit protection on power distribution lines with a nominal voltage of 1000 V or less. It acts as the main switch for on/off switching between the power and load circuit. It is built with a simple design that includes a tripping element, an action element, and a contact system. The working principle of the device is based on the heat generated due to the flow of current in the device, and when the temperature reaches a certain limit, the circuit breaker trips and opens the circuit to prevent any further damage or fire hazards.
