Circuit Breakers

Circuit breakers are a key component in the electric power system and protect electrical devices and circuits from damage due to increased current. The LELHPK11-30930-1 is a type of circuit breaker used for residential and commercial applications. It is important to understand its application field and working principle for proper installation and operation.

Application Field

The LELHPK11-30930-1 circuit breaker is a single phase breaker designed to protect lighting circuits, small motors, and other residential and commercial circuits. It is typically used for indoor applications in 120V and 240V electrical systems. It features a push-to-test button so electricians can easily test the condition of the breaker, as well as one pole only operation that eliminates both the nuisance of a phantom trip and the delay of the reset time.

Working Principle

The working principle of a circuit breaker is based on the protection of the electrical circuit against overloads. When an excessive amount of current passes through a circuit, the breaker automatically trips and causes an interruption of the current flow. The LELHPK11-30930-1 has a thermal-magnetic circuit breaker system that works using both heat and magnetism. The thermal part of the mechanism is responsible for detecting excessive current, while the magnetic part acts by tripping quickly when dealing with sudden issues like short circuits.

The LELHPK11-30930-1 circuit breaker features a robust design that offers protection against both ground faults and over-voltage. It also has a higher sensitivity to trips when compared to other circuit breakers and can trip within as little as 0.02 seconds. Additionally, the breaker is often paired with an indicator light that illuminates when the breaker trips, helping electricians easily identify when an issue has occurred.

Conclusion

The LELHPK11-30930-1 circuit breaker is an important device and widely used across many residential and commercial applications. It is designed to protect circuits from over-voltage and ground faults to ensure the safe operation of any electrical system. It possesses a thermal-magnetic circuit breaker system that uses both heat and magnetism, and features a robust design that ensures an immediate response in case of an emergency. Understanding the application field and working principle of this type of circuit breaker is essential for the proper installation and operation of the circuit breaker.
