Circuit Breakers play a very important role in the protection and control of various power systems. In particular, BR2C35UC is a circuit breaker with advanced characteristics for improved performance in medium voltage applications and is widely used in the power industry in recent years. This article will discuss the application field and working principle of BR2C35UC.

The BR2C35UC is an electro-magnetic type circuit breaker with a rated voltage of 12 kV and rated current of 630 A. It is suitable for both indoor and outdoor applications, and is certified for corrosion protection in areas with a high level of humidity. It has two functions, breaking and making, which are achieved through its two-armature structure. One armature is released to break or make the circuit, while the other armature is used to provide increased insulation and make the breaker less prone to false tripping. The breaker also features low operating temperature and is designed to reduce the maintenance needs.

In terms of application field, BR2C35UC circuit breaker is suitable for protection and isolation of various medium voltage power systems, including motor feeds and transformer power supplies. It can also be used in networks that require breaking faults in order to quickly isolate the problem area. It is usually used in the star points of transformers, as well as in generator switches, inverters, and air conditioner starters, and can be used for networking devices such as telecom facilities, fire protection devices, etc.

In terms of working principle, BR2C35UC is a two-armature circuit breaker which utilizes an electromagnetic force to create a breaking action. The arc is triggered when the closing contact of the breaker moves, creating a spark which is deflected by the arc shield into a suppression chamber. The spark is then extinguished by the explosion of hydrogen gas which is released from the hydrogen spring of the breaker. As a result, current circuiting is interrupted. To make the circuit again, the closing contact has to be returned to its original position.

In summary, BR2C35UC is an advanced electro-magnetic type circuit breaker with a rated voltage of 12 kV and rated current of 630 A. It is suitable for protection and isolation of various medium voltage power systems, and its two-armature structure is used for breaking and making operations. Its working principle is based on a magnetic force to create a breaking action, which is then interrupted by the release of hydrogen gas from the breaker. As a result, it is widely used in the power industry in recent years.
