Circuit breakers are an integral part of any electrical system. They serve as protection devices, designed to protect circuits from the risk of shorts, overloads, and other electrical faults. The LELK1-1RS4-30452-75 is a type of circuit breaker specifically designed for industrial applications. This article explains the application field of the device and its working principles.

Application Field of the LELK1-1RS4-30452-75

The LELK1-1RS4-30452-75 circuit breaker is designed for use in industrial applications, such as oil and gas, mining, infrastructure, manufacturing, and other high-risk environments. The device is designed to provide protection from electrical faults, power surges, or other voltage fluctuations that can damage costly equipment. In addition, the device can detect and react to a variety of electrical faults, such as wiring or circuit board errors, to provide its protection in any environment.

The device is UL 489B listed, meaning that it has undergone rigorous testing to meet the UL standard. This includes testing for the accuracy of its operating characteristics, temperature stability, and electrical strength. Additionally, the device has been designed to meet the highest standards of safety and performance in any situation.

Working Principles of the LELK1-1RS4-30452-75

The LELK1-1RS4-30452-75 circuit breaker employs a unique system of detection and reaction to protect a circuit from damage. The device contains two thermo-magnetic sensing elements: the main sensing element and a backup. The main sensing element is an electro-mechanical device that constantly monitors the voltage in the circuit. It detects when the voltage exceeds certain threshold values and triggers the breaker.

The backup sensing element is a thermal device that activates when a phase or current imbalance is detected. This element monitors the temperature of the circuit to identify risk of overheating, then acts to open the breaker if it determines the temperature is rising too quickly. Finally, the device is equipped with a current-limiting feature that helps protect expensive equipment from an overload of current.

By combining advanced features, both electro-mechanical and thermally-sensitive, the LELK1-1RS4-30452-75 circuit breaker provides protection in a wide range of industrial applications. With its UL listed components, it offers unmatched protection from shorts, overloads, wiring errors, and other electrical faults.
