Circuit breakers play a pivotal role in protecting the safety and reliability of electrical circuits. When there is over-current, over-voltage, short-circuit, or other anomalous situations, quickly break the circuit to isolate the fault area, prevent the fault from being expanded and further damage the equipment, and protect personnel and property safety. LELK1-1REC4-38770-15-V circuit breaker is one of the commonly used high-grade circuit breakers, especially suitable for places where motor control occurs. It is widely used in places with rated voltage up to 690V and rated current up to 1600A, such as power plants, substations, factories, mines and other places. LELK1-1REC4-38770-15-V circuit breaker belongs to the intermediate circuit breaker, which is used as the main switch in the power system. Its function is to switch on or switch off the circuit to control the start, stop and braking of motor, or to protect the power system when overload or short circuit occurs. Because of its outstanding performance and strong interruption capability, it has been widely used in various occasions. In terms of working principle, LELK1-1REC4-38770-15-V circuit breaker is composed of moving contact and static contact, of which the moving contact will move in the axial direction during operation and cut off the circuit, which is driven by a spring with fixed force. When the moving contact is closed, the contact end is pressed by the pushing force of spring, and the self-loosening phenomenon of the contact surface will not occur in the process of repeated switching on and off. When the overload or short-circuit fault occurs, the overcurrent release device in the circuit breaker will operate. Its working principle is that when the overload or short-circuit fault occurs, the release plunger in the circuit breaker is connected to the external power supply, so that the electromagnet core is attracted by the electromagnet to move the circuit breaker armature and contactor, thus cutting off the circuit. The advantages of LELK1-1REC4-38770-15-V circuit breaker are as follows. Firstly, its contact gap is wide, so the contact surface has good flexibility. Secondly, its arc absorption capability is strong, and it has the ability to break small capacity. Thirdly, the operation speed is fast and the release is sensitive. Fourthly, the structure is simple and the volume is small. Fifthly, the insulation performance is reliable and the working life is long.From the above analysis, it can be seen that LELK1-1REC4-38770-15-V circuit breaker is a very reliable and efficient product, which is widely used in places with rated voltage up to 690V and rated current up to 1600A such as power plants, substations, factories, mines and other places. With its outstanding performance, high safety and good stability, it can play a very good role in protecting the safety of personnel and property.
