Circuit breakers have been a staple of electrical systems since the industrial revolution. The JLE-1-0REC4-30908-200 is no exception, providing a powerful yet reliable short circuit protection. This article will analyze the application field and working principle of this device.

Application Field

The JLE-1-0REC4-30908-200 circuit breaker is designed for medium voltage applications, such as in substation and industrial settings. Its voltage can range from 0.25kV to 38kV, and it has a current range of up to 26,500A. It is capable of protecting both three-phase and single-phase systems, making it a versatile option for high-powered circuits. The compact size of the device allows it to be used in smaller installations, such as switchboards. Additionally, its dielectric strength makes it suitable for use in environments with potentially hazardous conditions, such as rain or snow, as well as damp or corrosive atmospheres.

Working Principle

The JLE-1-0REC4-30908-200 circuit breaker utilizes a combination of mechanical components and electrical components to provide short circuit protection. Its mechanical elements comprise a series of contact arms, along with a latch, which open and close the contacts with the help of a handle to control the flow of electricity. When an overload occurs, the current passes through an arcing component located in the contact arm, which causes a spark and melts the contact material, thus breaking the circuit. This feature is typically referred to as arc interruption. The breaker also contains an electromagnetic releasing device, which causes the contacts to open during an over-current situation. This feature ensures that the breaker will not remain in an overloaded condition for any longer than necessary, thus protecting the electrical components from further damage. The breaker is also equipped with an automatic recloser, which allows the contacts to close after a predetermined period of time. This helps to minimize downtime and ensure that the circuit remains protected.The JLE-1-0REC4-30908-200 circuit breaker is a reliable and robust device, providing short circuit protection for a wide range of applications. Its mechanical and electrical components work together to provide safe and efficient operation.
