Circuit breaker plays an important role in electric power system, it can provide a quick means of protection to the distribution system and apparatus against abnormal or abnormal situation of fault, overload and short circuit and thus ensure normal operation of the system. LELK1-32191-40-V is a type of circuit breaker, known as a voltage sensitive breakers. This article will introduce its application field and working principle.

LELK1-32191-40-V mainly applies to low voltage system, such as residential, industrial, commercial and infrastructure applications. Its maximum system voltage is up to 600V or below and it can work in temperature range of 0 to 70℃. This type of circuit breaker also has flexible installation, as it can be used in panel mount, device mount and wall mount horizontal or vertical positions. All in all, the LELK1-32191-40-V can be used in many different applications and it is easy to install.

The LELK1-32191-40-V circuit breaker is a new type of protection device. It is temperature sensitive with a temperature range of 0 to 70℃. The circuit breaker uses principle of thermal-magnetic tripping,which means that it uses both heat and magnetism in order to trip the circuit. The thermal component is controlled by a bimetallic strip that reacts to an increase in temperature due to an electrical overload. When the temperature of the bimetallic strip to a certain value, the contacts of the circuit breaker open, thus the completely breaking of the circuit is achieved.

Besides, the magnetic component of LELK1-32191-40-V is complex, it is made up of trip coil and trip actuator. The trip coil is activated when the contact current exceeds the rated value. When the trip coil is activated, the trip actuator pull the trip bar quickly, then the contact of the circuit breaker open, the circuit breaking is achieved. This process is relatively fast and it is the main advantage of LELK1-32191-40-V circuit breaker.

In conclusion, the LELK1-32191-40-V is one of the most popular circuit breaker which is widely used in low voltage system all over the world. It features flexible installation, excellent thermal-magnetic tripping, and rapid circuit breaking. Thus, it is trusted as a reliable and efficient circuit breaker, which brings much convenience to people’s life.
