Introduction

Circuit breakers, also known as circuit protectors, are devices used to disconnect electrical power in the event of an overload or short circuit. LEG6-40800-20-V is a type of circuit breaker designed to handle high voltage applications. It is used in a wide range of applications, including motor control centers and high voltage power grids. In this article, we will look at the application field and working principle of the LEG6-40800-20-V circuit breaker.

Application Field

The LEG6-40800-20-V circuit breaker is used primarily in areas where high voltage or high current levels are required. Its primary application field is in motor control centers, where it is used to control the current to motors, protecting them from any potentially damaging surge or overload. It is also used in high voltage power grids to disconnect the power supply quickly and safely in the event of an overload or short circuit.

Working Principle

The LEG6-40800-20-V circuit breaker works by monitoring the current flow within the circuit. When a short circuit or overload occurs, the circuit breaker will open the circuit, cutting off the flow of electricity and protecting the devices connected to it. The LEG6-40800-20-V circuit breaker has a number of components, including a tripping system, which contains the solid state trip unit (STU) and over-current trip unit (OTU). The STU monitors the current in the circuit and the OTU measures the magnitude of the current. If the current suddenly increases, the STU will trip the circuit breaker and cut off the power supply in order to protect the connected devices.The LEG6-40800-20-V circuit breaker also has a reset mechanism. Once the power supply has been shut off, the reset mechanism can be used to switch the power back on. This will allow the circuit breaker to reset and the current to be monitored again.

Conclusion

The LEG6-40800-20-V circuit breaker is an essential piece of equipment for a range of high voltage and high current applications. It works by monitoring the current within the circuit, and in the event of an overload or short circuit, it will disconnect the power supply quickly and safely. This ensures that the connected devices are protected from any potentially damaging surge or overload current.
