Circuit Breakers

Circuit breakers are essential components of electrical systems, providing critical protection from overcurrent faults and other hazards. LELBXK1-35243-4-V is a type of circuit breaker designed for use in low-voltage and medium-voltage applications. In this article, we\'ll look at the application field and working principle of LELBXK1-35243-4-V circuit breakers.

Application Field

LELBXK1-35243-4-V circuit breakers are suitable for low-voltage applications up to 690 Vac, as well as medium-voltage applications up to 3,000 Vac. The breakers are available in multiple configurations and can be used to protect both single-phase and three-phase systems. The LELBXK1-35243-4-V is suitable for a wide range of applications, including residential, commercial and industrial installations.

Working Principle

LELBXK1-35243-4-V circuit breakers operate on the principle of the melting of a fusible element. The circuit breaker contains an internal bimetallic strip which is heated by a current flowing through it. When the current reaches a critical level, the strip will expand and break the electrical circuit, thus interrupting the current.

The circuit breaker also contains a manually operated switch which is used to reset the breaker. This switch acts on the bimetallic strip, allowing it to cool and return to its normal position. The breaker is then ready for subsequent operation.

In addition to the manual reset, the LELBXK1-35243-4-V circuit breaker also contains thermal and/or magnetic trip elements, which can trip the circuit breaker automatically in the event of an overload or short-circuit. The trip elements are calibrated to respond to currents that exceed predetermined levels, thus providing increased safety and protection.

The LELBXK1-35243-4-V circuit breaker is a sophisticated device, offering comprehensive protection against overload, short-circuit and other electrical hazards. It is ideal for a variety of low-voltage and medium-voltage applications, and is highly reliable and easy to install and maintain.
