IELK21-28851-1-V Circuit Breakers

A circuit breaker is a device that is used to rapidly interrupt existing current if a fault or overload is detected. IELK21-28851-1-V circuit breakers are designed to open and close electrical circuits efficiently and to protect equipment from overloads.

Application Field

The IELK21-28851-1-V circuit breaker is specially designed for 300A applications. The device can be used for the protection of motors, short-circuits, overloads, and as a selector switch in various industries. In addition, the IELK21-28851-1-V can be used in residential and commercial settings.

Working Principle

The IELK21-28851-1-V circuit breaker works on a principle of electromagnetism. A magnetic field is generated around the breaker when the current passes through. This field is then detected by the circuit breaker. When the current is too high, it causes a disruption in the magnetic field and the breaker trips, opening the circuit and interrupting the flow of electricity.

The IELK21-28851-1-V circuit breaker has a trip time of 50 ms, and a response speed of 1 cycle per second. The device is designed to withstand high inrush current, up to 20 times the rated current of 300A. The circuit breaker can be reset manually.

The IELK21-28851-1-V circuit breaker offers various protections, such as current overload, short circuit, and motor protection. The device is also designed to withstand extreme temperatures, from -40°C to 125°C. The breaker also has a high dielectric strength of 4 kV.

Conclusion

The IELK21-28851-1-V circuit breaker is an advanced device that is designed for 300A applications. It can be used in various industries, residential, and commercial settings for the protection of motors, short circuits, overloads, and as a selector switch. The device works on a principle of electromagnetism, and is designed to detect high levels of current. It offers high speed responses, up to 1 cycle per second, and a trip time of 50 ms. It is also designed to withstand high inrush currents and extreme temperatures.
