Circuit breakers are an essential component of electrical systems and serve an important safety role. As the name implies, circuit breakers are devices that are designed to break a circuit when an excess of current passes through it. UPL51-2464-1 is a specific type of medium voltage circuit breaker that is used in the electricity industry. This article will discuss the application field and working principle of this type of circuit breaker.

Application Field
Medium voltage circuit breakers are designed for applications with an electrical supply of up to 36 kilovolts. UPL51-2464-1 is a reliable circuit breaker specifically designed for medium voltage applications. It can be used in a variety of areas such as industrials, constructions, renewables, and marine operations.
UPL51-2464-1 is designed to protect against faults including phase-to-phase, phase-to-ground, overcurrent and short-circuit. It is also durably manufactured with modern technology, which ensures that it can handle the toughest of industrial environments.
The UPL51-2464-1 is designed for outdoor installations, but can also be used in indoor applications such as those found in automated transmission and distribution systems.

Working Principle
UPL51-2464-1 is an air-break circuit breaker, meaning it uses compressed air to separate the contacts of the circuit breaker when a fault is detected. It works by using an electrically operated actuating system. Once an overcurrent or short circuit is detected, an electric motor will activate the mechanism. This will compress air into a tank, which then presses against the contact pins of the UPL51-2464-1 circuit breaker. This pressure is enough to separate the contacts, thus breaking the circuit and preventing further flow of current.
The UPL51-2464-1 also features a mechanically interlocked system, which allows the contacts to be locked into place. This is a key safety feature and ensures that the circuit breaker cannot be inadvertently reset if the fault is still present.

Conclusion
UPL51-2464-1 is a medium voltage circuit breaker designed specifically for industrial environments. It is used to protect against short circuits and overcurrents, and is highly reliable and durable. The working principle of the UPL51-2464-1 consists of an electrically operated actuating system which compresses air into a tank, thus breaking the circuit when a fault is detected. Additionally, the UPL51-2464-1 features a mechanically interlocked system which keeps the contacts locked together until the fault is resolved. This highly efficient circuit breaker can be used for outdoor and indoor applications, making it a great choice for the electricity industry.
