Circuit breakers are one type of electrical device that are used to protect circuits against damage caused by over-current and over-voltage. They are designed to break and reset the electrical connection when a fault or an overload condition occurs. The LELHK11-1-62-50.0-AU-01-V is an example of a circuit breaker that has been designed for specific applications and needs. In this article, we will discuss the application field and working principle of the LELHK11-1-62-50.0-AU-01-V.

Application Field

The LELHK11-1-62-50.0-AU-01-V circuit breaker is designed to be used for medium voltage applications. This type of breaker is typically used in transformer substations, large commercial or industrial sites, and other high voltage applications. It can handle currents up to 50 kA and has a voltage rating of 15-52kV. It is designed to be used as a circuit breaker, switch, or fuses. It is rated for use with AC or DC power.

The LELHK11-1-62-50.0-AU-01-V is designed to be used in harsh environments and is suitable for outdoor use. It is made from aluminum or stainless steel and is designed to be resistant to corrosion. It is rated IP44 for dust and water resistance. It has an operating temperature range of -40°C to +65°C.

Working Principle

The LELHK11-1-62-50.0-AU-01-V circuit breaker uses a thermal-magnetic operating principle. This means that when the current through the circuit breaker exceeds the over-current protection settings, the breaker will trip and open the circuit. The thermal element of the breaker is designed to detect and respond to overloads or short circuits by breaking the connection between the poles. Meanwhile, the magnetic element enables the breaker to detect surges and other voltage irregularities.

The LELHK11-1-62-50.0-AU-01-V has built-in safety features such as a circuit breaker lockout mechanism, a ground fault indicator, and a trip delay circuit. When the over-current protection is tripped, the integrated mechanism immediately locks out the circuit, preventing any further current from flowing. The ground fault indicator helps to quickly identify any ground fault condition and the trip delay circuit helps to protect the breaker from nuisance trips caused by momentary voltage spikes.

The LELHK11-1-62-50.0-AU-01-V circuit breaker is designed with an indicator light that signals when the breaker is on or tripped. This light helps to inform operators of the current status of the breaker and allows for quick visual identification. The breaker also includes an over-voltage protection trip indicator.

Conclusion

The LELHK11-1-62-50.0-AU-01-V circuit breaker is a reliable device that is designed to provide medium voltage protection for a variety of applications. It uses a thermal-magnetic operating principle and includes a variety of safety features to ensure safety and reliability. It is designed for outdoor use and has been proven to be resistant to corrosion and other environmental conditions. This makes it an ideal choice for most medium voltage applications.
