Circuit Breakers

Circuit breakers are electrical switches designed to protect the electrical circuit from overload and short-circuit damage. They are essential components of any electrical system. The LELHK111-1REG4-39524-1-V circuit breaker is a type of thermal-magnetic circuit breaker designed to protect the electrical system from overvoltage and overheating. It has a number of features that make it an ideal choice for a wide range of circuit protection applications.

Application Field

The LELHK111-1REG4-39524-1-V Circuit Breaker is primarily used as a general-purpose circuit breaker in residential, commercial, and industrial installations. It can be used to protect circuits from overloads, short-circuits, and voltage transients. Additionally, the breaker can be used in applications where higher protection levels are required, such as power supplies, UPS systems, and electronic equipment.

The LELHK111-1REG4-39524-1-V circuit breaker can also be used in branch circuits. This type of breaker is designed to prevent overcurrent and short-circuit conditions in branch circuits. It features a thermal-magnetic release design, which allows it to operate as either a thermal or magnetic circuit breaker. This makes it an ideal choice for applications that require higher protection levels.

Working Principle

The LELHK111-1REG4-39524-1-V Circuit Breaker has a two-stage protection system. The first stage protection is provided by the thermal-magnetic release design, which is activated when the temperature of the circuit increases due to an overload or short-circuit condition. When the thermal element of the circuit breaker senses an increase in temperature, it trips and interrupts the power supply to the protected circuit.

The second stage protection is provided by the magnetic release design. When an overload or short-circuit condition occurs, the magnetic element of the circuit breaker trips and interrupts power supply to the protected circuit. The magnetic release design also ensures that the circuit breaker will remain tripped even after the current returns to normal levels. This provides added protection against future overloads or short-circuit conditions.

The LELHK111-1REG4-39524-1-V Circuit Breaker is a highly reliable and effective device that provides optimal protection against overvoltage and overheating. Its two-stage protection system ensures that the protected circuits are shut down safely and quickly in the event of an overload or short-circuit condition.
