Application Field and Working Principle of LMLB1-1RLS4-36405-15-V Circuit Breakers

Circuit breakers are essential tools used in the installation and maintenance of electrical dependencies and electrical systems. This is particularly true for LMLB1-1RLS4-36405-15-V circuit breakers. This type of circuit breaker is intended for use in low voltage AC installations ranging from 480V to 600V, with a rated short-circuit current of up to 15kA. This article will discuss the various application fields and working principles of LMLB1-1RLS4-36405-15-V circuit breakers.

Application Fields of LMLB1-1RLS4-36405-15-V Circuit Breakers

The application fields of LMLB1-1RLS4-36405-15-V circuit breakers are numerous. The most common application field is in households and residential buildings, where it is used to control the power supplied to electrical appliances and other electrical circuits. It can also be used as a main switch in industrial plants to facilitate discrete equipment operation. Additionally, it is used in the distribution and control of power in power plants and substations. The breaker is rated for a current of up to 15kA, which makes it suitable for medium-sized to large-scale electrical power distribution.

Working Principle of LMLB1-1RLS4-36405-15-V Circuit Breakers

LMLB1-1RLS4-36405-15-V circuit breakers operate on the principle of thermal-magnetic action. This means that they are designed to detect both temperature rise and current overload conditions in order to protect against short-circuit current or overloading conditions. To detect an overload, the circuit breaker incorporates an electromagnet, which creates a magnetic field when current flows through it, and a bimetallic strip, which is designed to deform when heated by an excessive current. When the current reaches a predetermined threshold, the electromagnet will immediately deactivate the contact, resulting in an open circuit state. Upon cooling, the bi-metallic strip will resume its original position, allowing the breaker to close the contacts again, thus restoring power to the circuit.

Advantages of LMLB1-1RLS4-36405-15-V Circuit Breakers

The LMLB1-1RLS4-36405-15-V circuit breaker offers various advantages over other types of circuit breakers due to its thermal-magnetic design. These advantages include a higher sensitivity to detect an overload, a high interrupting capacity (up to 15kA), a higher tripping speed, and a robust design that ensures a longer working life. The breaker also supports dynamic rating calculations, allowing it to accurately adjust its rated current to the actual load.

Conclusion

In conclusion, LMLB1-1RLS4-36405-15-V circuit breakers are widely used for low voltage power distribution in households, industrial plants, and power plants. These breakers are designed to work on a thermal-magnetic principle, which allows them to be highly sensitive and more reliable than other types of circuit breakers. These breakers offer a range of advantages, such as higher sensitivity, higher interrupting capacity, faster tripping speed, and a longer working life, while their dynamic rating calculation capabilities ensure that they can accurately adjust their rated current to the actual load.
