Circuit breakers are an essential component of the electrical systems that serve our homes, workplaces, and other facilities. They are responsible for protecting us from potential electrical dangers and preventing major damage to the systems that use electricity. An example of a circuit breaker is the LMLC1-1RLS4-34087-48-V.

Application Field

The LMLC1-1RLS4-34087-48-V circuit breaker is commonly used in residential and commercial applications, such as electrical panels and branch circuits. It is designed to provide interrupt protection as well as overcurrent protection in low and medium voltage applications. This type of circuit breaker is able to handle up to 48 volts and is capable of interrupting up to 7500 amps.

This type of circuit breaker is also suitable for use in hazardous areas and can be used to protect circuits in high-voltage systems, such as those used in applications such as medical facilities, airports, and nuclear power plants. It is also suitable for residential applications, such as homes and light commercial buildings.

Working Principle

The LMLC1-1RLS4-34087-48-V circuit breaker operates according to the molded-case circuit breaker principle. This type of circuit breaker is composed of two components - the main contact and the overcurrent actuation. When the overcurrent actuation occurs, the main contact trips the circuit breaker.

The main contact is composed of two metal plates that are connected to each other by a spring. When the current passing through the circuit exceeds a certain level, the force of the current will cause the metal plates to move apart, causing the circuit breaker to trip. This is known as "trip current", which is typically set at a higher level than the normal current passing through the circuit.

The overcurrent actuation is composed of an arc chute that contains a series of metal fuses that act as trip points. When the current level passing through the circuit rises above a certain level, the arc chute responds by triggering a process that results in an interruption of the flow of current.

The LMLC1-1RLS4-34087-48-V circuit breaker is also capable of providing lockout protection. This function uses a lockout mechanism, which is activated in the event that the circuit breaker is not de-energized within a certain period of time. This helps to ensure that the circuit breaker is not reset until all of the system’s safety protocols have been followed.

The LMLC1-1RLS4-34087-48-V circuit breaker is a reliable and efficient circuit breaker suitable for a wide range of applications. It is designed to provide overcurrent protection and ensure the safety of circuits in residential and commercial buildings. Furthermore, its lockout protection feature helps to ensure that all safety protocols are followed.
