Circuit Breakers: UPL1-7007-70 Application Field and Working Principle

Circuit breakers are electricity-protecting devices used to prevent overloads, short-circuits, surges, or power outages for safety and to protect equipment, appliances, and residential wiring. The UPL1-7007-70 is a miniaturized three-phase circuit breaker with a modular design perfect for large-scale power systems. With its versatile adaptation range, high quality, and excellent protection, the UPL1-7007-70 has found wide application and remains popular for a variety of applications.This article will provide an overview of the application and working principle of the UPL1-7007-70 circuit breaker.

Application of UPL1-7007-70

The UPL1-7007-70 is a reliable choice for medium and high voltage systems. It can be used in single- and three-phase power grids and is designed for use in any location, indoors or outdoors.The circuit breaker is rated for a voltage of 690V AC and a maximum current of 70A, making it suitable for use in residential and commercial applications. It can also be used in a wide range of industrial applications, including electric motors, pumps, generators, air-conditioning, and electric heating systems.The UPL1-7007-70 is a robust and reliable device and has been used in numerous high-profile projects, including the optimization of electricity in Tajikistan and the development of the electricity grid in Nepal.

Working Principle of UPL1-7007-70

The UPL1-7007-70 uses the thermal-magnetic mechanism for its working principle. This mechanism is based on two principles: 1) Thermal principle: this principle is used to automatically disconnect the circuit in the event of an overload. This is done using a bimetallic strip which bends when it comes in contact with heat. This bending is used to separate and open the contacts, effectively breaking the circuit. 2) Magnetic principle: this principle is used for fast disconnection in the event of a short circuit. This is done using an electromagnet which is energized when a high current flows through the circuit breaker. The electromagnet then generates a powerful magnetic field, which is used to separate and open the circuit breaker contacts, breaking the circuit.The combined use of both principles allows for efficient and reliable protection of electricity equipment. The circuit breaker also features adjustable trip levels which allow the user to set the desired currents on the device for better protection.

Conclusion

The UPL1-7007-70 circuit breaker is a reliable and versatile device, designed for use in a wide range of applications. Its thermal-magnetic working principle provides efficient and reliable protection against electrical overloads and short circuits, and the adjustable trip levels allow users to customize the device for optimal protection.
