IELHK111-30284-4-V Application Field and Working Principle of Circuit Breakers

Circuit breakers play an important role in industrial and technological activities. They are used to protect the safety of people and property and prevent the occurrence of potential hazards due to electrical overloads, short circuits, and other abnormal conditions. The IELHK111-30284-4-V is one type of circuit breaker. It is designed to provide over-current protection of single phase AC circuits. The breaker features a thin film technology, contact design, efficient structure and reliable operation.

Application Field

The IELHK111-30284-4-V circuit breaker is designed for use in industrial and commercial applications. It can be used for protection in a range of different settings, including local distribution systems, sub-distribution systems, home appliance systems, motor protection systems, lighting systems, and air-conditioning systems. This breaker has a number of advantages. It can provide reliable over-current protection and maximum forward voltage operation, making it suitable for maximum forward voltage appliance systems. The breaker is also resistant to vibration and shock, and is designed to operate and maintain reliability in a wide range of temperatures.

Working Principle

The IELHK111-30284-4-V circuit breaker is equipped with a thermal-magnetic trip unit, which consists of a thermal element and a magnetic element. The thermal element is responsible for detecting high temperatures caused by over-currents or short circuits. When the current rating exceeds the rated value of the breaker, the internal temperature of the breaker\'s contact will rapidly increase, causing the thermal element to trip and breaking the circuit. The magnetic element is responsible for detecting overload currents. The magnetic element has a set of current sensing coils and a piston that moves in response to the current passing through the coils. When the current exceeds the rated value of the breaker, the coils produce a magnetic field that causes the piston to move, thereby tripping the breaker and breaking the circuit.

Conclusion

Overall, the IELHK111-30284-4-V is a reliable and efficient circuit breaker designed for use in industrial and commercial applications. Its thin film technology, contact design, and efficient structure make it highly suitable for a range of settings. It features thermal-magnetic trip unit, consisting of a thermal element and a magnetic element, that provide protection against over-currents and short circuits.
