Circuit Breakers: LMLK1-1RLS4-36184-30-V Application Field and Working Principle

Circuit breakers are essential components used in modern power systems for the purpose of protecting electrical networks and apparatus from damaging currents, overvoltage and short circuits. They are designed to sense a fault condition and automatically disconnect the circuits from the system. This article discusses the application field and working principle of a specific circuit breaker, the LMLK1-1RLS4-36184-30-V.

Application Field

The LMLK1-1RLS4-36184-30-V circuit breaker is suitable for use in a wide range of applications, including AC networks with rated voltage of up to 440V, a rated current of up to 50A, and a rated frequency of up to 50Hz. It is designed for one- and three-phase power systems, and can be also be used to protect against overload and short circuit. Additionally, the breaker can be used in applications such as air conditioning, telecommunications, and industrial machines.

Working Principle

The LMLK1-1RLS4-36184-30-V circuit breaker is based on the thermal-magnetic working principle. This means that it is composed of two independent systems: a thermal system, responsible for responding to overload conditions, and a magnetic system, responsible for responding to short circuit conditions.The thermal system contains a bimetallic strip that is sensitive to temperature changes. This strip is connected to a set of contact fingers, which close the breaker when heat is applied (i.e. when an overload is detected). The magnetic system contains an electromagnet, which is activated by a large short-circuit current. This current causes the movement of a plunger, which also controls the contact fingers. When the plunger is pulled out, the contact fingers are open and the breaker is disconnected from the circuit.

Conclusion

The LMLK1-1RLS4-36184-30-V circuit breaker is designed for multiple applications, from air-conditioning to industrial machinery. Its thermal-magnetic working principle, composed of a thermal system based on a bimetallic strip, and a magnetic system based on an electromagnet, is responsible for providing fast and accurate protection against both overvoltage and short circuit.
