LMLBXK1-1RLS4-52-8.00-A-M3-V

Circuit breakers are an integral part of any electrical system. They offer protection against over-voltage or over-current, and prevent damage to the system by disconnecting sections of the circuit upon detecting imbalances or overloads in the system. The LMLBXK1-1RLS4-52-8.00-A-M3-V is a type of circuit breaker used for medium voltage applications. This article will examine the application field and working principle of the LMLBXK1-1RLS4-52-8.00-A-M3-V circuit breaker.

Application Field

The LMLBXK1-1RLS4-52-8.00-A-M3-V is a compact, multi-standard circuit breaker, designed for medium voltage applications. It can be used in power distribution systems rated up to 3.3 kV, and is suitable for both indoor and outdoor installations. It features a quick-trip mechanism which allows it to interrupt short-circuits as soon as they are detected, thus ensuring the safety of the system. Further, its compact size makes it ideal for use in tight spaces, such as behind switchboards.

Working Principle

The working principle of the LMLBXK1-1RLS4-52-8.00-A-M3-V circuit breaker is based on the thermal-magnetic protection principle. In this principle, the circuit breaker has a thermal element and a magnetic element, both of which can protect the system from overloads and short-circuits. The thermal element of the circuit breaker is based on the Joule heating effect. When an overload occurs in the system, the flow of current generates heat, which is detected by the thermal element. The thermal element then trips the circuit breaker, breaking the circuit and preventing damage.

The magnetic element of the circuit breaker is based on the Lorentz force. When a short-circuit occurs in the system, the flow of current generates a magnetic field, which is detected by the magnetic element. This causes the trip mechanism to be activated, breaking the circuit and preventing damage.

The LMLBXK1-1RLS4-52-8.00-A-M3-V circuit breaker also features an adjustable operating time, which allows it to respond differently depending on the severity of the problem. This feature is adjustable through a time-delay knob which is located on the body of the circuit breaker. With this knob, the user can choose the amount of time the circuit breaker should take to trip upon detecting an overload or short-circuit.

The LMLBXK1-1RLS4-52-8.00-A-M3-V circuit breaker is a reliable and durable medium voltage circuit breaker. Its thermal and magnetic protection elements ensure the safety of the system, while its adjustable operating time allows it to respond differently to different problems. Through these features, the LMLBXK1-1RLS4-52-8.00-A-M3-V circuit breaker provides excellent protection for medium voltage electrical systems.
