Circuit breakers are an important part of electrical equipment that protect electrical circuits and enable power to be switched off in case of an overload or fault. The R21-62F-4.00A-B07EV is a type of circuit breaker that has an unusually high current rating, and is usually used in applications where large amounts of electrical current may be required. In this article, we’ll discuss the application fields and working principle of the R21-62F-4.00A-B07EV circuit breaker.

Application Fields

The R21-62F-4.00A-B07EV circuit breaker is often used in environments where high current loads are needed, such as data centers, industrial production and manufacturing sites, light rail systems, and transmission systems. This circuit breaker is particularly useful for the safe shutdown of large current applications, as the 4.00A current rating is substantially higher than the standard 3.00A rating of other breakers. In addition, the R21-62F-4.00A-B07EV circuit breaker is more versatile than other circuit breakers, in that it can be used in multiple applications, such as motor overload protection as well as short circuit protection.

Working Principle

The R21-62F-4.00A-B07EV circuit breaker is designed to trip and cut power or reset when an overload or short circuit occurs on the electrical system. It is designed to respond quickly to the tripping or opening of a circuit and provides protection against overloaded circuits and short circuits. The circuit breaker trips when the current passing through the breaker reaches 4.00A, which is achieved when a certain amount of heat is generated in the heating element of the circuit breaker.

Once the circuit breaker trips, it will remain open until its reset button is pressed. The reset button has to be pressed manually in order for the circuit breaker to be reset and electricity to start flowing again. This manual reset process ensures that the circuit breaker is not immediately reset when the overload or short circuit is cleared.

Conclusion

The R21-62F-4.00A-B07EV circuit breaker is particularly suitable for applications where large amounts of current may be needed or where multiple motors or loads are connected, as its high current rating provides enhanced protection. Its versatile design means that it can be used in a variety of applications, including motor overload and short circuit protection. The manual reset process ensures that the circuit breaker cannot be reset unless it is done so manually, thus providing safety and peace of mind.
