Circuit breakers are electrical safety devices used in both domestic and commercial applications to protect people and property from electrical circuit overloads or shorts. R29-20128-1-V is an example of a circuit breaker designed for specific applications. This article will discuss the application fields and working principle of this type of circuit breaker.

Application Field of R29-20128-1-V Circuit Breaker

R29-20128-1-V circuit breakers are specifically designed for protecting high voltage power distribution systems. They are typically used in places like power plants, substations, and other large power distribution circuits. They are also used for protecting electrical circuits in the residential, commercial and industrial sectors.

The R29-20128-1-V circuit breaker has been designed to meet a variety of requirements including high DC and AC voltage applications, quick-trip operations, and arc-resistant operation. It also features a curved magnetic path that reduces the current that is required to trip the breaker while still providing the necessary protection against electrical overloads. It has also been designed to be extremely reliable and capable of withstanding short circuit currents of up to 25000A.

Working Principles of R29-20128-1-V Circuit Breaker

The R29-20128-1-V circuit breaker uses the two most common methods for protecting electrical circuits: thermal and magnetic protection. Thermal protection works by detecting the amount of current that is flowing through the circuit. If the current reaches a predetermined level, the circuit’s contacts will open, thereby cutting off the power supply to the protected circuit. Magnetic protection works by detecting when an arc is discharged in a protected circuit. When this happens, the breaker contacts are opened automatically, cutting off the power supply.

The R29-20128-1-V Circuit Breaker also features a special arc-resistant mechanism which prevents the formation of an arc when the breaker contacts are opened. This is achieved by quickly reducing the current that is flowing through the breaker contacts and using magnetic forces to close the contacts. This ensures that no arc will form, thus providing safe and reliable operation.

Conclusion

The R29-20128-1-V Circuit Breaker is an advanced and reliable electrical safety device designed for protecting high voltage power distribution systems. It features both thermal and magnetic protection and also includes an arc-resistant mechanism to prevent arcs from forming when the breaker contacts are opened. This makes the R29-20128-1-V an ideal choice for protecting electrical circuits in industrial, residential and commercial applications.
