Circuit breakers are essential components in electrical power systems. They are used to prevent damage from electrical surges, protect against overloads and short circuits, and maintain the correct voltage level. The BR2C5UC is a type of circuit breaker manufactured by the BR2C5UC Corporation. This article will discuss the application field and working principle of the BR2C5UC.

Application Field of BR2C5UC Circuit Breaker

The BR2C5UC circuit breaker is designed for use in a variety of different electrical power systems. Its rugged design makes it suitable for use in industrial, commercial and residential applications. Some of the common applications of the BR2C5UC include:

• Power distribution systems
• Motor control centers
• Industrial machinery control panels
• Heating, ventilation and air conditioning (HVAC) systems
• Lighting control systems
• Switching systems

The BR2C5UC is capable of interrupting high current faults, up to 20,000 amperes. It is suitable for use in AC/DC systems, with voltage ratings ranging from 690V to 13,800V. It is available in both manual and motor-operated designs.

Working Principle of BR2C5UC Circuit Breaker

The BR2C5UC circuit breaker utilizes a tripping mechanism to detect and interrupt currents beyond the rated values. When an overload or short circuit occurs, an increase in current is detected by the sensing or trip unit, which triggers the release of the breaker’s contacts. This allows the breaker to perform its primary switch disconnecting function.

The BR2C5UC also employs the use of trip detectors. This feature allows the breaker to detect rising currents over a normal current quickly. The detectors then activate the tripping mechanism to quickly disconnect the circuit. This helps to protect the circuit from any damage due to over current.

The BR2C5UC also includes thermal magnetic protection. This protection is used to detect gradual increases in current and prevent damage from prolonged overloads. The thermal-magnetic protection device consists of a bimetallic strip and a magnetic armature. The bimetallic strip is heated by the current, which causes it to bend, activating the armature and releasing the breaker’s contacts.

The BR2C5UC also features inverse time tripping, which allows the breaker to detect an abrupt increase in current and interrupt it quickly. When an abrupt increase in current is detected, the breaker’s contacts are opened sooner than with normal overcurrent protection. This helps to protect the equipment against any damage caused by the surge of current.

Finally, the BR2C5UC is equipped with a manual reset button. This allows operators to manually reset the breaker if it trips due to an overload or short circuit. This is especially useful in cases where resetting the breaker is necessary while it is still under load.

Conclusion

The BR2C5UC is a reliable and durable circuit breaker designed for use in a variety of power systems. It is capable of interrupting high currents, and features advanced trip detectors, thermal-magnetic protection, and inverse time tripping. It also includes a manual reset button which allows operators to manually reset the breaker if necessary. This makes the BR2C5UC an excellent choice for any electrical power system.
