Circuit Breakers

Circuit breakers are essential components in any electrical system. They are designed to protect the system from overloads, short circuits and other fault conditions. One circuit breaker that is commonly used in many applications is the LeLK1-1RS4-27129-944.

Application Field

The LeLK1-1RS4-27129-944 is a type of circuit breaker specifically designed for three-phase power systems. It is designed for a wide range of industrial and commercial applications, including building energy distribution, motor control circuits and commercial installations. It features a wide range of current ratings, as well as adjustable trip settings.

The LeLK1-1RS4-27129-944 is also suitable for use in harsh and hazardous environments, such as those found in some marine and oil and gas applications. The circuit breaker is UL listed, meaning it meets the safety standards for a variety of industries. This makes it suitable for a wide range of applications.

Working Principle

The LeLK1-1RS4-27129-944 circuit breaker features an adjustable overcurrent protection mechanism. This protection mechanism is designed to prevent the breaker from tripping in normal circuit conditions, while still providing protection against dangerous overloads. The overcurrent protection setting is adjustable, which allows the user to tailor the breaker’s trip level to the application.

The LeLK1-1RS4-27129-944 is also equipped with a thermal-magnetic trip mechanism. This mechanism responds to both overvoltage or undervoltage conditions as well as high current levels. When the breaker senses an overvoltage or undervoltage condition, it will immediately open the circuit. Similarly, if the current exceeds the adjustable trip level, the breaker will open the circuit to protect the system from an overload.

The LeLK1-1RS4-27129-944 also features an instantaneous trip mechanism. This mechanism is designed to instantly provide protection against short circuits and other dangerous fault conditions. When the breaker senses a short circuit, it will immediately open the circuit. This prevents the system from being damaged by the high currents and voltage associated with short circuits.

Conclusion

The LeLK1-1RS4-27129-944 is a type of circuit breaker specifically designed for three-phase power systems. It is suitable for a wide range of industrial, commercial and hazardous applications. It features adjustable overcurrent protection and both thermal-magnetic and instantaneous trip mechanisms, providing protection against overloads, undervoltages, overvoltages and short circuits. The LeLK1-1RS4-27129-944 is an essential component in any electrical system.
