Circuit Breakers: LELZXK12-1REC5-71273-45-G2 Application Field and Working Principle

Circuit protection is an essential part of any electrical system, and modern circuit protection devices range from basic overload switches to specialized air circuit breakers. Devices such as the LELZXK12-1REC5-71273-45-G2, commonly referred to as a circuit breaker, provide a high level of protection, allowing current to be interrupted effectively when necessary. In this article, we will examine the application field and working principle of the LELZXK12-1REC5-71273-45-G2 circuit breaker.

Application Field of the LELZXK12-1REC5-71273-45-G2 Circuit Breaker

The LELZXK12-1REC5-71273-45-G2 circuit breaker is designed for both indoor and outdoor applications. It is a 4-pole circuit breaker designed to protect personnel and equipment from damage due to overcurrent conditions. This device can be used in a wide variety of different applications such as residential, commercial, industrial, and recreational installations.

For outdoor applications, the LELZXK12-1REC5-71273-45-G2 circuit breaker has been specially designed to withstand the rigors of harsh outdoor conditions including high temperatures, humidity, dust, and sunlight. This device provides reliable protection in situations with fluctuating power levels, frequent cycling on/off, and motor protection. This makes it an ideal choice for locations such as pool houses, irrigation systems, pumps, and other outdoor applications.

Working Principle of the LELZXK12-1REC5-71273-45-G2 Circuit Breaker

At its most basic level, a circuit breaker is a switch that opens and closes a circuit. When the circuit is closed, it allows current to flow through the circuit. When the protective device (the circuit breaker) detects that the current is greater than the threshold, it trips and opens the circuit, effectively interrupting the flow of power. The LELZXK12-1REC5-71273-45-G2 circuit breaker is designed to provide this type of protection.

The LELZXK12-1REC5-71273-45-G2 circuit breaker is equipped with three trip settings: normal, long-delay, and short-delay. The normal setting is designed for normal, everyday usage. The long-delay setting is designed to delay the trip so that short-term or transient overloads are ignored. This setting is ideal for applications that may experience long startup surges. The short-delay setting is designed to trip the circuit quickly so that dangerous overloads are stopped before damage can occur. This setting should be used in applications where sudden overloads are expected.

The LELZXK12-1REC5-71273-45-G2 circuit breaker features a thermal-magnetic design, which allows it to effectively detect both thermal and magnetic overloads. The thermal element is designed to detect high temperatures due to the current overloads, while the magnetic element is designed to detect current surges that would not necessarily increase the temperature of the breaker. This combination of thermal and magnetic protection provides a highly reliable level of protection.

In addition, the LELZXK12-1REC5-71273-45-G2 circuit breaker is designed with a manual override, which allows the breaker to be manually opened if needed. This feature is useful in situations where the breaker may be needed for maintenance or inspection.

Conclusion

The LELZXK12-1REC5-71273-45-G2 circuit breaker is a versatile device that can be used in a variety of applications including residential, commercial, industrial, and recreational installations. It offers reliable protection against both thermal and magnetic overloads, and has three adjustable trip settings so that it can be adjusted to the specific needs of the application. Additionally, the LELZXK12-1REC5-71273-45-G2 circuit breaker is designed with a manual override, providing an additional layer of protection when necessary.
