Circuit Breakers

Circuit breakers are an important part of any electrical system, providing protection from overloads, short circuits and other dangerous conditions that could cause damage to the system or harm to its users. One type of circuit breaker, the LEL1-30428-15, is designed for high current applications and provides an additional level of reliability and safety for installations. In this article, we\'ll explore the application field and working principle of the LEL1-30428-15 circuit breaker.

Application Field

The LEL1-30428-15 circuit breaker is suitable for a variety of residential, commercial, and industrial applications. It\'s typically used in high current applications, such as motor or HVAC systems, where it can provide fast, reliable protection in the event of an overload or short circuit. This type of circuit breaker can also be used in secondary distribution, power distribution systems, and other applications with high current loads.

The LEL1-30428-15 breaker is especially well suited to use in harsh, hostile environments due to its special epoxy coating, which helps to protect the device from corrosion, dust, and moisture. It also features high overcurrent protection, excellent environmental performance, and low temperatures and high vibration resistance compared to other breakers.

Working Principle

The working principle of the LEL1-30428-15 circuit breaker is based on the thermal-magnetic principle of operation, which combines a bi-metallic element with a magnetic current sensing element. This type of circuit breaker has two separate operating elements, each of which performs an important function within the device.

The first element, the bi-metallic element, is spring-loaded and senses sudden changes in current, temperature, or pressure. This element is responsible for detecting the presence of an overcurrent and causing the circuit breaker to open. The second element, a magnetic current sensing element, is responsible for sensing gradual increases in current. When the current reaches the breaker\'s predetermined trip point, the magnetic element causes the bi-metallic element to expand, activating the breaker and opening the circuit.

The LEL1-30428-15 circuit breaker also features a manual reset, which can be used to reset the breaker and restore power in the event of a tripped circuit. This reset is usually accessible from the front panel of the device. This feature makes the LEL1-30428-15 an excellent choice for applications that require a manual reset.

Conclusion

The LEL1-30428-15 circuit breaker is a versatile, high-performance device designed for a variety of high current applications. It provides reliable protection against overcurrents and shorts, and its special epoxy coating helps protect it from corrosive environments. Its thermal-magnetic operating principle ensures fast, reliable circuit protection and its manual reset feature makes it suitable for applications that require manual reset capability. With its high current and harsh environment capabilities, the LEL1-30428-15 is an ideal choice for a variety of applications.
