Circuit Breakers are designed to protect electrical circuits and equipment from damage due to overcurrent, short circuit and other faults. The LEL1-28080-2 is a type of circuit breaker that is used in high-voltage applications. It is designed to interrupt the flow of current in the event of an overcurrent, short circuit or other fault conditions. This article will explain the application field and working principle of the LEL1-28080-2.

Application Field of the LEL1-28080-2

The LEL1-28080-2 is a three phase circuit breaker that is suitable for applications up to 690v AC and 440v DC. It is ideal for use in high voltage industrial environments such as large commercial buildings, factories, and power distribution systems. It is also suitable for use in the automotive industry and marine applications. The breaker is designed to interrupt high-voltage currents in the event of overcurrents or short circuits in the system. It is capable of interrupting up to 80kA RMS symmetrical fault current.

Working Principle of the LEL1-28080-2

The working principle of the LEL1-28080-2 is based on the electrical principles of current interruption. When an overcurrent or short circuit fault occurs in the system, the breaker “senses” the condition and quickly interrupts the current flow. The breaker uses a combination of mechanical and electrical components to achieve this. The mechanical components include a trip arm, a latch, and a release mechanism. The electrical components include an overcurrent detection circuit and an electromagnet. When an overcurrent condition is detected by the overcurrent detection circuit, the electromagnet is energized, causing the trip arm to move and the latch to be released. This causes the release mechanism to trip, which interrupts the flow of current in the circuit. The breaker then resets automatically after the fault is cleared.

Conclusion

The LEL1-28080-2 is a three-phase circuit breaker designed for high-voltage applications. It is suitable for use in industrial, marine and automotive environments. The working principle of the breaker is based on the principles of current interruption. The breaker uses mechanical and electrical components to detect and interrupt the flow of current in the event of an overcurrent or short circuit fault condition.
