Circuit breakers are essential for ensuring the safety and continuity of a electrical circuit. The LELK1-1REC4-27129-931 is one such circuit breaker model, designed to protect electrical components and systems from short circuiting, overloading, and other dangerous events.

This specific model is equipped with 12kV rated voltage, 100A rated current, IEC60947-2, 8 pole, and 25kA breaking capacity. It is an air circuit breaker (ACB), most commonly installed in commercial, industrial and domestic electrical networks.

The LELK1-1REC4-27129-931 is a molded case circuit breaker (MCCB) series. It features enhanced circuit protection, integrated differential protection, and other motor control features. Its robust design is designed for long life and reliable operation.

The main functions of the LELK1-1REC4-27129-931 are to break the circuit (open-circuit protection) when the current reaches a specified level or to disconnect the circuit from sources of high voltage (over-voltage protection). Furthermore, this model is equipped with thermal-magnetic tripping and adjustable trip times for improved protection.

The working principle of the LELK1-1REC4-27129-931 is based on the thermal effect of an electrical current on a metal part. The heat generated by an electrical current passing through a metal element causes the element\'s temperature to increase proportional to the current amount. When the current exceeds a certain threshold, the element\'s thermal expansion trips the breaker, breaking the circuit before the overload can cause damage.

Another component of this breaker\'s working principle is magnetism. The LELK1-1REC4-27129-931 is equipped with an electromagnetic trip mechanism. This system uses a magnet to sense rapid changes in the circuit current (short circuits, overloads, etc.) and triggers the breaker to open the circuit.

In addition to being used as an overload protection device, the LELK1-1REC4-27129-931 also offers protection from damage caused by power surges, grounding faults, and unnatural load transitions. Its intrinsic features and advanced sensing features make it ideal for use not just in commercial and industrial applications, but also in the domestic setting.

The LELK1-1REC4-27129-931 is the perfect example of a well-designed circuit breaker. It offers robust protection against electrical shock, over-currents, and other hazardous situations while allowing the circuit to remain properly functioning.
