Circuit Breakers

Circuit breakers are essential components of modern day electrical systems. They are designed to protect electrical systems from overvoltage and overcurrent, which can cause significant damage to the system and endanger personnel. In modern power systems, the SU2C35UC is a popular OEM circuit breaker. This type of circuit breaker offers a range of functions and benefits, including a reliable trip curve, a wide voltage range, a low tripping current, and a compact size.

Application Field

The use of SU2C35UC circuit breakers can be divided into two main application fields: industrial and residential. In the industrial field, they are typically used as overvoltage and overcurrent protection in switchgear assemblies and distributed power systems. They can also be used to protect motors, lighting circuits, transformers, and other equipment. In the residential field, they are typically used in single- and three-phase breaker panels.

Working Principle

The SU2C35UC circuit breaker has a series of relay contacts that are used to break the circuit when an overvoltage or overcurrent condition is detected. This type of breaker works by detecting the instantaneous voltage, current, or power that is present on the line. When the threshold value is exceeded, the relay contact opens, disconnecting the load from the line and preventing damages to the system and personnel. They also have a trip-coil that senses changes in the current and interrupts the flow to the circuit when it reaches a predetermined level.

The SU2C35UC is equipped with a range of functionality, including a manual reset, a pre-alarm, a power monitor and data logger, a bimetallic overload and thermal shut-off, as well as adjustable time delay and trip characteristics. These features provide extra protection and improved performance, making them ideal for industrial and residential applications.

Conclusion

The SU2C35UC circuit breaker is a reliable and robust device that is widely used in many industrial and residential applications. It offers a wide range of features and benefits, such as a reliable trip curve, a wide voltage range, a low tripping current, a compact size, and adjustable time delay and trip characteristics. These features make it an ideal choice for protecting electrical systems from overvoltage and overcurrent, ensuring system integrity and personnel safety.
