LMLB1-1RLS4-35530-4-V Circuit Protection

Circuit breakers are an essential piece of electrical equipment used in power systems. This equipment provides protection against electrical faults while allowing normal operation. The LMLB1-1RLS4-35530-4-V is a single pole 10A circuit breaker, designed for medium voltage applications. In this article, we will discuss the application field and working principle of this circuit breaker.

Application Field of LMLB1-1RLS4-35530-4-V Circuit Breaker

The LMLB1-1RLS4-35530-4-V circuit breaker is mainly used in medium voltage switchgear applications. It can be used in indoor as well as outdoor environments. The LMLB1-1RLS4-35530-4-V circuit breaker has a dielectric strength of 1000A and a short circuit breaking capacity of 48 kA. It offers several other features to ensure safe and reliable operation such as overcurrent protection, motor operator protection, manual on/off switch and an auxiliary contact. The circuit breaker also has a built-in relay, which helps to detect any on-load faults and automatically trips the breaker in case of an overcurrent or short circuit event.

Working Principle of LMLB1-1RLS4-35530-4-V Circuit Breaker

The LMLB1-1RLS4-35530-4-V circuit breaker is a combination of a switch and an overcurrent protection device. The switch is used to manually open or close the circuit and the protection device is used to automatically trip the switch in the event of an overcurrent or short circuit. The circuit breaker has an arc-moving coil which is connected to the overcurrent protection system. If the current in the circuit exceeds the rated capacity, the arc-moving coil pushes the overcurrent protection mechanism which initiates the tripping mechanism. The switch is then automatically disconnected from the power supply.

The circuit breaker also has a manual reset button. Once the switch is disconnected from the power supply, the manual reset button can be used to restore the switch to its normal state. This allows for the normal operation of the circuit breaker, while the overcurrent protection system is still in place to protect against any future faults.

In conclusion, the LMLB1-1RLS4-35530-4-V circuit breaker is an essential piece of electrical equipment designed for use in medium voltage switchgear applications. This circuit breaker offers advanced protection against electrical faults and can be easily reset after a fault has occurred. It is a reliable and cost-effective solution for power system applications.
