BR1C25UC

Circuit Breakers

Circuit breakers are an integral part of the electrical circuit used for various applications. They act as the electric system’s safety switch, protecting the entire system from damage from overvoltage, short-circuit, or overload. Circuit breakers are categorized according to operating voltage, current rating, and type of breaking mechanism. BR1C25UC is a high-voltage circuit breaker used in medium/high-voltage applications.

BR1C25UC Application Field and Working Principle

The BR1C25UC Circuit Breaker is a three-pole device used in the medium/high-voltage range of up to 12kVAC. In addition, the breaker has a current rating of up to 25kA and a voltage rating of 0.5-5kVAC. It is widely used in a variety of applications such as overhead lines, substations, and installations in industrial buildings or ships.

The working principle of the BR1C25UC circuit breaker is based on the inverse-time delayed action of an electromagnetic force. When a fault current is detected, the force acts to open the main contacts, thus interrupting the current flow. The operating mechanism uses a number of internal components such as contacts, springs, and springs, as well as an operating drive. The internal mechanism ensures that the breaker operates correctly and safely in any given situation.

The BR1C25UC circuit breaker also has a number of safety features that protect the device. These include overcurrent protection, thermal protection, and short-circuit protection. The overcurrent protection feature ensures that the breaker does not operate in situations where excessive current is present, as this could lead to serious damage to the system. The thermal protection feature ensures that the breaker does not operate in situations where the temperature exceeds the specified limit. The short-circuit protection feature helps to prevent the breaker from operating in cases where a short circuit is present.

The BR1C25UC is an extremely reliable circuit breaker and is designed to be used in a wide range of applications. It is particularly suitable for applications that require high-level protection, as it is capable of operating in any situation. Additionally, the internal safety features help to protect the system from any possible damage.
