Circuit breakers are devices found in almost all places and are an important part of any electrical power system. They are used to protect against overloads that might occur in a circuit, as well as being able to manually open and close circuits for maintenance or safety reasons. The 4230-T120-K0DE-30A is a type of circuit breaker, and it is important to understand both the application and the specific workings of this device.

Application Fields

The 4230-T120-K0DE-30A is a type of molded-case circuit breaker (MCCB). This type of breaker is mainly used in high-current and low-voltage applications, as they are better suited to handle both systems than other types of breakers. The rated amperage of the 4230-T120-K0DE-30A is 120A and its rated voltage is 600V, making it an ideal choice for domestic, industrial, and commercial applications using low voltage, such as circuit wiring in buildings and machine tools.

It is also widely used in under and over current power protection systems, power distribution industry, energy metering, power quality maintenance systems, and various other protection circuits. The breaker is designed for use in harsh environments, as it has an increased resistance to shock, vibration, and heat. Further, the breaker has been designed to meet all relevant under and over current power protection regulations, providing extra protection for customer loads.

Working Principle

The 4230-T120-K0DE-30A is a tripping type circuit breaker and it has the capability to detect and isolate fault current in the system. The tripping mechanism works on the principle of thermal-magnetic characteristics, wherein two principle components of the breaker work in tandem to detect overloads and short circuits. The basic design involves a bimetallic element and a current transformer. When the current passing through the breaker exceeds the rated level, the bimetallic element is quickly heated causing it to expand, while the current transformer senses the excess current in the circuit and creates a magnetic field to initiate the tripping process. Once the breaker trips, the circuit is separated and the current flow automatically stops.

In the case of manual operation, a handle is available on the exterior of the breaker which can be used to manually switch it on and off. Additionally, the breaker has both overload and short circuit trip indication, making it easy to identify any issues. Lastly, the breaker also has an adjustable adjustable short-circuit trip level, making it suitable for use in a variety of application environments.

Conclusion

The 4230-T120-K0DE-30A is a type of circuit breaker designed for use in a wide range of low voltage applications. It has a rated voltage of 600V, a trip current of 120A and an adjustable short-circuit trip level. The working principle of the breaker is based on the combination of a bimetallic element and a current transformer and it can be used to both protect from overloads andShort or open circuits. This breaker is commonly found in domestic, industrial, and commercial applications, making it a great choice for any electrical power system.
