Circuit Breakers

IELK1111-1REC4-33713-3-V application field and working principle

Circuit breakers are widely used in modern society, from industrial control to home appliances. As an important part of electric power system, circuit breakers can quickly cut off the fault current and protect the safety of system and personnel. It is for this reason that the IELK1111-1REC4-33713-3-V circuit breaker has become very popular.

The IELK1111-1REC4-33713-3-V circuit breaker is mainly used in electric power systems and electrical distribution systems of high rise building buildings. It is a 6 pole LCD air break circuit breaker with a rated operating voltage of 800V and a rated operating current of 150A. The rated short circuit breaking capacity of the IELK1111-1REC4-33713-3-V circuit breaker is 40kA, which is the highest in the current market. In addition, it has a variety of overcurrent protection functions, such as overload protection, short circuit protection and arc protection.

The working principle of the IELK1111-1REC4-33713-3-V circuit breaker is mainly based on the use of the electromagnetic force of the solenoid. When the short-circuit current passes through the solenoid coil, the electromagnetic force will be generated, and the force will close the contact between the breaker and cut off the current automatically. In the case of overload or when the current reaches its rated value, the circuit breaker will trip and cut off the current automatically to protect the safety of personnel and equipment.

In addition, the IELK1111-1REC4-33713-3-V has a special design of arc extinguishing chamber, which can quickly extinguish the arc generated when the switch contacts are cut off. The arc extinguishing chamber uses a combination mode of current forcing and spark gap to ensure that the arc is quickly extinguished without scattered radiation.

In summary, the IELK1111-1REC4-33713-3-V circuit breaker has good application field and working principle, and the use of such circuit breakers can effectively protect personnel safety and equipment system operation. Therefore, it is widely used in various industries such as electric power, electrical distribution and high-rise building buildings.
