Circuit Breakers: LELHK11-1-52-5.00-01-V Application Field and Working Principle

Circuit breakers are common and essential components of electrical circuitry. Circuit breakers protect electrical systems against overloads and short circuits, providing critical protection to both electronic components and people from electric shock and system damage. The LELHK11-1-52-5.00-01-V is a single-pole, single-throw, thermal-magnetic circuit breaker used in residential, commercial, and light industrial applications. In this article, we will discuss the application field and working principle of the LELHK11-1-52-5.00-01-V circuit breaker.

Application Field

The LELHK11-1-52-5.00-01-V thermal-magnetic circuit breaker can be used in a range of industrial and residential applications, including circuit protection of high-voltage (220V-1200V) and low-voltage (14V-277V) systems, circuit protection of various watt-regulated power applications, anti-arc short circuit protection, and motor overload protection. This circuit breaker is ideal for applications in which limited circuit protection is needed and the breakers need to be reset quickly and automatically once caused by an abnormal voltage, current, or temperature.

Working Principle

The LELHK11-1-52-5.00-01-V circuit breaker consists of two separate parts, a thermal element and a magnetic trip unit. The thermal element is responsible for 0ver-current and over-temperature protection, while the magnetic trip unit provides short circuit protection.

When the thermal element is triggered, it will cause the contacts to open, cutting off power to the circuit. The thermal element is triggered when the current exceeds the rated current of the breaker, which is determined by the size of the circuit breaker.

When the magnetic trip unit is triggered, it will cause the contacts to trip, cutting off power to the circuit. This occurs when there is a sudden increase in current, such as an arc fault or short circuit.

Once the contacts are tripped, the circuit breaker must be reset manually by pressing the reset button. This will allow the power to be restored to the circuit. The circuit breaker is designed to limit short circuits, which can cause significant damage to electronic components.

Conclusion

The LELHK11-1-52-5.00-01-V single-pole thermal-magnetic circuit breaker is an invaluable addition to any electrical system. It is designed to protect systems from overloads and short circuits, providing critical protection from electric shock and damage to system components. This circuit breaker can be used in a range of industrial and residential applications and is capable of resetting automatically once tripped. The working principle of the LELHK11-1-52-5.00-01-V circuit breaker involves two separate parts, a thermal element and a magnetic trip unit, which provide protection against current, temperature, and short circuit.
