Circuit breakers can be used in many applications, from consumer to industrial. One example of a circuit breaker is the R21-4-.500A-R102CV-S-V. This device is especially useful when it comes to protecting vulnerable equipment. The purpose of this article is to provide an overview of the application fields and working principles of this type of circuit breaker.

Application Fields of the R21-4-.500A-R102CV-S-V

The R21-4-.500A-R102CV-S-V is designed for use with single-phase circuits and has a maximum voltage of 480V AC. It can also be used with medium-voltage applications, but its maximum current rating is lower than that of most other circuit breakers. The typical applications for the R21-4-.500A-R102CV-S-V include residential homes, commercial buildings, and industrial facilities.

Working Principle of the R21-4-.500A-R102CV-S-V

The R21-4-.500A-R102CV-S-V is a thermal-magnetic type circuit breaker, meaning that it is triggered by both temperature and current overload. The thermal-magnetic operation combines the benefits of both thermal and magnetic circuit breakers. When a temperature overload is detected, the circuit breaker trips quickly. This minimizes the amount of damage to the equipment. The magnetic operation, on the other hand, takes longer for the circuit breaker to trip. This delays its response, but allows for better protection against overcurrents.The R21-4-.500A-R102CV-S-V also features a manual reset button. This allows users to reset the breaker without having to replace it. The reset button is useful for troubleshooting purposes.

Conclusion

The R21-4-.500A-R102CV-S-V is a thermal-magnetic type circuit breaker that is designed for use with single-phase circuits. It has a maximum voltage of 480V AC and can be used in residential, commercial, and industrial applications. The thermal-magnetic operating principles of the device provide both fast temperature sensitivity and better protection against overcurrents. The manual reset button is an additional feature that makes the device easy to use and troubleshoot.
