Circuit breakers are vital components of any electrical system. They play an important role in protecting the electrical system from damage caused by short circuits, overloads, and other faults. In modern electrical systems, circuit breakers are available in a variety of configurations that can be used for specific applications. One such circuit breaker is the UPG6-21616-10, which is used in medium voltage systems. This article will discuss the application field and working principle of the UPG6-21616-10 circuit breaker.

The UPG6-21616-10 circuit breaker is a vacuum circuit breaker (VCB) that is designed for medium voltage applications in the range of 3.6 to 40.5kV. The main features of this breaker include its high breaking capacity, low power consumption, and long mechanical life. It is suitable for operation in systems up to a rated short-time current of 63kA and short-time withstand current of 85kA. The UPG6-21616-10 is commonly used in large-scale power systems, particularly in remote distribution systems. It can be used in both indoor and outdoor applications, and its construction makes it resistant to harsh environmental conditions.

The working principle of the UPG6-21616-10 circuit breaker is based on the vacuum arc-extinction method. When the breaker is closed, it allows current to flow through the electrical system. The arc-extinction mechanism occurs when the operating field locks in and creates an arc, causing the arc to extinguish in a vacuum chamber. This mechanism is effective in preventing arcs from reigniting and thus preventing any damage to the system. The UPG6-21616-10 also has a current-limiting feature, which reduces the peak current and dissipates it quicker. This helps protect the system from any damage caused by sudden spikes in current.

The UPG6-21616-10 circuit breaker is an excellent choice for medium voltage applications, as it is reliable and easy to maintain. It is designed for a long service life and can withstand harsh environmental conditions. Additionally, the arc-extinction mechanism and current-limiting features make it a safe and efficient solution for electrical systems. As such, the UPG6-21616-10 is ideal for remote distribution systems, industrial power systems, and other medium voltage applications.
