Circuit Breakers

Circuit breakers are electrical safety devices that are used to protect circuits and equipment from the risks of overload, short circuit, or earth fault. There are many types of circuit breakers available in the market, each with different capabilities and features to suit individual needs. The LELK11-1-52-15.0-B-01-V is one such type of breaker, designed to serve applications from 15 to 400 amp. In this article, we will discuss its application field and working principle.

Application Field

The LELK11-1-52-15.0-B-01-V circuit breaker is a one-time trip molded case breaker with one pole and a voltage rating of 380-440 volts. It is primarily used in industrial applications, such as large-scale power distribution systems, buildings, transportation systems, and industrial equipment. It is also suitable for applications such as power distribution systems in schools, hospitals, and office spaces.

The LELK11-1-52-15.0-B-01-V features an adjustable trip current rating from mid-range to full-range, allowing it to be used in applications with varying current requirements. It also offers a wide range of motor protection features, including high and low trip point settings, motor time delay, and adjustable automatic restart settings.

Working Principle

The working principle of the LELK11-1-52-15.0-B-01-V circuit breaker is to protect circuits and equipment from the risks of overload or short circuit. When a fault is detected, the breaker trips and the circuit is cut off from the power supply, thus protecting the circuits and the connected equipment from damage.

The circuit breaker\'s trip current rating is determined by the current flowing through the circuit when the breaker trips. The current must be greater than the trip current rating for the breaker to trip. The adjustable trip current feature allows the trip current rating to be adjusted within the given range (mid-range to full-range).

The LELK11-1-52-15.0-B-01-V also comes with motor protection settings. The adjustable motor trip point allows the user to set a specific current limit for the motor, thus avoiding motor overloads. The motor time delay setting ensures that the breaker doesn\'t trip if there is a minor power interruption or motor inrush. The adjustable automatic restart setting (speed or delay) allows the user to control the speed or delay the time of motor restart.

Conclusion

The LELK11-1-52-15.0-B-01-V is a one-time trip molded case breaker with one pole and a voltage rating of 380-440 volts. It is used mainly in industrial applications, such as large-scale power distribution systems, buildings, transportation systems, and industrial equipment. It offers adjustable trip current rating from mid-range to full-range, motor protection features, and adjustable automatic restart settings. The working principle of the circuit breaker is to protect circuits and equipment from the risks of overload or short circuit by cutting off the power supply once a fault is detected.
