Circuit breakers are essential components in any electrical system. They are used to protect equipment and components from being damaged or destroyed due to overcurrents and short circuits. The LELK1-1RS4-30452-3 is an example of such a device. In this article, we will discuss the application field and the operating principle of this circuit breaker.

LELK1-1RS4-30452-3 circuit breakers are mainly used in control panels, which are devices used to regulate the flow of electricity in a system. They are often used in industrial settings such as manufacturing, mining and power generation facilities. They can also be found in residential settings such as homes and apartments. The circuit breakers are used to protect equipment and wiring from being damaged or destroyed from overvoltages, short circuits and other electric faults.

The LELK1-1RS4-30452-3 circuit breaker is designed to interrupt the current flow when the current exceeds the predetermined threshold. It does this by utilizing a movable contact arm, which is connected to a flexible link. The arm is spring loaded and when the current exceeds the threshold, the link or arm bends, thus breaking the electrical connection.

At the heart of this circuit breaker is a bimetallic strip. The strip is composed of two different metals, which have different thermal expansion properties. When the current flows through the circuit breaker, it causes a temperature rise, which in turn causes the bimetallic strip to bend. This movement causes the contact arm to bend and break the electrical connection.

The LELK1-1RS4-30452-3 is also equipped with a manual reset switch, which can be used to reset the circuit breaker in the event of a power outage or other type of interruption in the current flow. The switch also serves as a failsafe in case the circuit breaker fails to activate in a timely manner.

The LELK1-1RS4-30452-3 circuit breaker is designed to protect equipment and wiring from being damaged or destroyed from overvoltages, short circuits, and other electric faults. It is an economical and reliable device that can be used in residential, commercial and industrial settings. Its operating principle is based on the thermo-mechanical properties of a bimetallic strip and it has a manual reset function to ensure its performance in the event of a power outage or other interruption in the current flow.
