Circuit breakers: 219-4-6388-101 Application Field and Working Principle

Circuit breakers are the most important tool in any electrical system. They are designed to protect against electrical issues such as power malfunctions, short circuits, and ground faults. They are also commonly used to control the flow of electricity. A circuit breaker works by detecting and then interrupting an excessive flow of current in an electrical circuit.

Application Field

The 219-4-6388-101 circuit breaker is designed for automatic protection against overload and short circuit conditions. It is suitable for low and medium voltage applications and as an interface between the power system and the load. This type of circuit breaker is often used in industrial applications, such as automation control systems, laboratories, and electric motors. It can also be used in residential applications, such as air conditioners and lighting.

Operating Principle

The 219-4-6388-101 circuit breaker is equipped with a thermal-magnetic trip device. The thermal-magnetic trip device is composed of a thermal element and a magnetic element. The thermal element acts as a heat sensor. It detects changes in the current in the circuit and throws a switch at a preset value, when the temperature of the conductor exceeds the current-limiting temperature of the circuit breaker. The magnetic element of the trip device senses an excessive electric current, which causes it to push the switch, thereby cutting off the power. The circuit breaker also has a manual reset button, which allows it to be reset after a power failure.

When the current in the circuit exceeds the trip level set by the thermal-magnetic trip device, it trips the breaker, disconnecting the circuit from the power. This ensures that there is no risk of fire or injury due to the fault in the circuit. The trip device also has adjustable settings, so the trip level can be adjusted to the maximum current needed for the application. After a fault occurs and the breaker trips, the manual reset button can be used to reset the breaker and restore power to the circuit.

Conclusion

The 219-4-6388-101 circuit breaker is a versatile device for controlling electricity in various residential and industrial applications. It is equipped with a thermal-magnetic trip device and a manual reset button, which allow it to quickly and safely disconnect an overloaded or short-circuited circuit, thus avoiding fire or injury caused by the fault. This type of circuit breaker is easy to install and use, making it a popular choice for any electrical system.
