Circuit breakers are often used to disconnect circuit parts in an electrical system. The LELK12-40416-1 is one type of circuit breaker that is often used in domestic and industrial applications. In this article, we will discuss the application field and working principle of this type of circuit breaker.

Application Field of LELK12-40416-1 Circuit Breaker

The LELK12-40416-1 is primarily used in industrial applications and is typically rated for a voltage of up to 415 V. This type of circuit breaker can be used to protect equipment against short circuits, overloads, and ground faults. It can also be used to open or close electrical circuits and is commonly used to control the flow of power in a system. Additionally, it is suitable for use in a wide range of places, such as motor control centers, switchgear, and control panels.

Working Principle of LELK12-40416-1 Circuit Breaker

The LELK12-40416-1 circuit breaker utilizes a thermal-magnetic type of technology to provide protection against short circuits and overloads. This type of circuit breaker consists of two components; the thermal-magnetic device and the over current trip unit. The thermal-magnetic device is a bimetallic strip that is heated when an overload or short circuit occurs. This causes the strip to expand which operates a lever that breaks the contacts of the circuit breaker. This action disconnects the circuit.

The other component, the over current trip unit, consists of a coil and an adjustable set of contacts. This unit is able to sense the current flowing through the circuit, and when this current exceeds a pre-determined level, the coil causes the contacts to open and disconnect the circuit. This type of circuit breaker is able to respond quickly and efficiently to overloads and short circuits, preventing further damage or harm.

Conclusion

The LELK12-40416-1 is a circuit breaker that is used in a variety of industrial applications. This type of circuit breaker is able to provide reliable protection against short circuits, overloads, and ground faults. It utilizes a thermal-magnetic type of technology and features two components; the thermal-magnetic device and the over current trip unit. This type of circuit breaker is able to act quickly and efficiently to disconnect circuits when necessary, providing effective protection against potentially dangerous situations.
