Circuit Breakers

Circuit breakers are an important component of any electrical system. They provide protection from large amounts of current by automatically shutting off the flow of electricity in the event of an overload or short circuit. The LMLKM11-1RLS4-34138-1002 is an example of a circuit breaker. This article will discuss its application field and working principle.

Application Field

The LMLKM11-1RLS4-34138-1002 circuit breakers are designed for use in electrical installations where high levels of current need to be protected. These include industrial, commercial, and residential applications. The breakers range in size from 1-30 Amps, and are rated for a variety of voltage classes, including 0-415V AC, 0-400V DC, and 0-415V DC. They are usable up to 1000V and can be used in applications with high motor loads and arc furnaces.

Working Principle

The LMLKM11-1RLS4-34138-1002 circuit breakers function by using a magnetic field to detect a surge in current. When an overload or short circuit occurs, the magnetic field causes a bimetal element to bend and force a spring-loaded motor to trip. This causes the breaker to open and the flow of electricity to stop. The bimetal element and motor then reset the breaker.

The LMLKM11-1RLS4-34138-1002 breakers also feature thermal and magnetic protection. Thermal protection uses a heat sensitive element to monitor the temperature of the circuit. If the temperature rises too high, the breaker trips. Magnetic protection uses a magnetic coil to detect an imbalance in the phase of the current. If the phase difference is too great, the breaker trips.

The LMLKM11-1RLS4-34138-1002 breakers also feature an auxiliary contact, which is used for monitoring the status of the breaker. A light or other device can be connected to the auxiliary contact, allowing the user to easily check whether the breaker is off or on.

Conclusion

The LMLKM11-1RLS4-34138-1002 circuit breakers are designed for use in a wide range of applications. They offer protection from large current surges by using a magnetic field, thermal, and magnetic protection. The auxiliary contact also allows the user to quickly check the status of the breaker.
