Circuit Breakers are an essential part of the electrical system, designed to protect circuits from dangerous and damaging over-current events. They perform the vital role of part of the power distribution system and provide circuit isolation, protection, switching and control for the electrical network.

The LELK1-1REC4-27129-923 is a type of circuit breaker. It is used to protect downstream equipment from overvoltage, overload and short circuit conditions. This circuit breaker can be used in both low and medium voltage applications. Its main features include a high breaking and making capacity, adjustable trip settings, and excellent coordination.

The working principle of a circuit breaker depends on the type. In the case of the LELK1-1REC4-27129-923, it relies on a thermal-magnetic operating principle. This means that it includes both a thermal tripping element and a magnetic tripping element. Together, these two elements work together to detect an overcurrent event, which triggers the opening of the circuit breaker.

The thermal element uses heat to detect an overload situation. A resistive heating device heats up during an overload and causes the current to trip the circuit breaker. This is done by the magnetic force created by the overcurrent causing a separation between the contacts that normally remain closed.

The magnetic element also works to detect overcurrents and/or a sudden change in current, called an inrush of current. An electromagnet is surrounded by an iron core, where the current is concentrated. During an overcurrent, the electromagnet is de-energized and the magnetic force produced pulls the lever away from the contacts, opening the circuit breaker.

The LELK1-1REC4-27129-923 is designed for use in a variety of circuit protection and control applications. These include switchgear, industrial equipment, motor protection and control, portable equipment, and residential and commercial installations.

The LELK1-1REC4-27129-923 provides excellent circuit protection, featuring a high breaking and making capacity, adjustable trip settings, and excellent coordination. This circuit breaker is also easy to install and maintain, and its small size makes it ideal for applications where space is at a premium.

In conclusion, the LELK1-1REC4-27129-923 is a type of circuit breaker used to protect downstream equipment from overvoltage, overload and short circuit conditions. It works by using a thermal-magnetic operating principle, utilizing both a thermal tripping element and a magnetic tripping element. It is designed for use in a variety of circuit protection and control applications, and its excellent features make it easy to install and maintain.
