Circuit breakers are an important part of any electrical system, and have been used for centuries in a variety of applications. The LELB1-1REC4-37719-100-R1-V circuit breaker is a modern model which is designed to provide safety and reliable operation. In this article, we will discuss the application field and working principle of the LELB1-1REC4-37719-100-R1-V circuit breaker.

The LELB1-1REC4-37719-100-R1-V circuit breaker is a type of molded case circuit breaker (MCCB). It is designed for use in a wide variety of low- and medium-voltage applications, ranging from residential, commercial, industrial and institutional uses. The circuit breaker has a rated ultimate interrupting capacity of 10,000A at 600V and a DC voltage rating of 1000V. It is capable of electrical monitoring, providing the user with a detailed assessment of the load current and power conditions.

The LELB1-1REC4-37719-100-R1-V circuit breaker is designed to interrupt an electrical circuit when a short circuit or a ground fault occurs. In normal operation, the circuit breaker senses the loads on the electrical circuit and maintains the current at a safe level. When a short circuit or a ground fault is detected, the circuit breaker trips, thus protecting the connected equipment and wiring.

The working principle of the LELB1-1REC4-37719-100-R1-V circuit breaker is based on thermal-magnetic operation. When the load current exceeds a predetermined threshold, a bimetallic strip in the circuit including the breaker trips the circuit, interrupting the current. Additionally, a magnetic field is created in the coil of the circuit breaker, which assists in the rapid opening of contacts to further protect the circuit.

The LELB1-1REC4-37719-100-R1-V circuit breaker also has an adjustable overload protection feature. This feature allows the user to set a maximum current level, at which the circuit breaker will trip if exceeded. This ensures that the circuit won’t be able to draw more current than it can safely handle.

In addition to its overload protection, the LELB1-1REC4-37719-100-R1-V circuit breaker also features fault protection. This protection monitors the circuit for an electrical short circuit or a ground fault. In the event of a short circuit or a ground fault, the circuit breaker trips in order to protect the circuit.

Overall, the LELB1-1REC4-37719-100-R1-V circuit breaker provides reliable and safe operation in a wide variety of applications. It is designed for both low- and medium-voltage systems, providing reliable overload and fault protection. Its thermal-magnetic operation finds the perfect balance between protection and energy efficiency.
