Circuit Breakers: R21-62-25.0A-32440-1 Application Field and Working Principle

Circuit breakers are an integral component in any electrical system. They are designed to protect a building’s electrical wiring from over current and short circuits. The R21-62-25.0A-32440-1 Circuit Breaker is one example of this type of device. This circuit breaker’s application field and working principle will be discussed in brief in the following sections.

Application Field

The R21-62-25.0A-32440-1 is particularly suitable as a protective device in main distribution systems, including home, industrial, and commercial applications. Its primary use is to protect against temporary overloading or short-circuits on electrical wiring. These load disturbances can be caused by faults in the wiring or external sources.

The design of the R21-62-25.0A-32440-1 allows it to act as a safety device to disconnect power in the event of an over current or short circuit situation. Furthermore, the circuit breaker is rated to carry up to 25 amps of current, and thanks to its size and compatibility, it can be installed in most junction boxes or panel boards. The device also boasts an impressive interrupt rating of 10kAIC at 240V AC.

Working Principle

The R21-62-25.0A-32440-1 is designed to interrupt an electric circuit in the event of an over current or short circuit situation. This is made possible by the use of a thermal-magnetic tripping mechanism. This system includes a bimetallic disc and a magnetic trip coil, which work in conjunction with one another. The bimetallic disc will expand and flex in response to high temperature, whereas the magnetic trip coil generates a magnetic field when current is passed through it.

When the current passing through the device exceeds the rated level, the magnetic field generated by the trip coil will become stronger. This, in turn, will cause the bimetallic disc to expand and distort, creating a “trip” mechanism which will break the circuit. This is what ultimately protects the device from short circuits and/or over currents.

The R21-62-25.0A-32440-1 also has an adjustable trip curve selector. This feature allows users to customize the tripping threshold of the device. This is especially useful in situations when the current draw may vary, or in systems where the current load is expected to rise. By adjusting the trip curve selector, the R21-62-25.0A-32440-1 can ensure a safe and efficient power distribution network.

In conclusion, the R21-62-25.0A-32440-1 is an efficient and effective circuit breaker, which is suitable for use in all types of electrical systems. Its thermal-magnetic tripping system ensures safety, while its adjustable trip curve selector provides ample customizability. By recognizing these features and the application field for which this device is intended, users can optimize their power distribution systems for improved efficiency and safety.
