Circuit Breakers: 4420.0865 Application Field and Working Principle

In any electronic system, circuit breakers play an essential role in the safety and stability of the system. The 4420.0865 series of circuit breakers are designed to protect medium voltage and high voltage networks from overloads and short circuits. It has a wide range of applications in industrial motors, industrial control systems, and electric grids.

Applications

The 4420.0865 series of circuit breakers are designed for use in medium and high voltage circuits. It can be used to protect industrial motors, industrial control systems, and electric grids from short circuits and overloads. It is also suitable for protecting equipment from low-frequency impulses and occasional overvoltage. Additionally, it has a short-circuit withstand capacity up to 50 ka rms symmetrical.

Working Principle

The 4420.0865 series of circuit breakers are designed to detect and trip automatically when an overload or short circuit is detected. The circuit breaker utilizes a magnetic field to open and close the circuit breaker. When an overcurrent is detected, the magnetic field trips the circuit breaker, allowing the current to be safely diverted away from the system. Additionally, the 4420.0865 series of circuit breakers features an automatic reset capability, allowing it to reset itself after a fault has been cleared.

Advantages

The 4420.0865 series of circuit breakers offer a wide range of advantages over other circuit breakers, including their robust and reliable performance, low maintenance requirements, and their low cost. Additionally, the 4420.0865 series of circuit breakers is designed with safety in mind, providing protection against overvoltage and overcurrent conditions. Furthermore, the circuit breakers are designed with a wide variety of features, such as adjustable current sensitive settings, built-in overload alarms, and manual reset capability.

Conclusion

The 4420.0865 series of circuit breakers are designed to protect medium and high voltage electrical systems from overloads and short circuits. The circuit breakers utilize a magnetic field to detect and trip the circuit breaker in the event of an overload or short circuit. Additionally, the circuit breaker features an automatic reset capability, allowing it to easily reset itself after a fault is cleared. The 4420.0865 series of circuit breakers offer a number of advantages, such as robust and reliable performance, low maintenance requirements, and low cost.
