Circuit Breakers

The R21-4-2.00A-34067-2-V circuit breaker is a powerful and reliable tool for controlling and managing electrical load, providing convenient and comprehensive safety protection for electronic and electric systems. This type of circuit breaker has a broad range of applications for residential, commercial and industrial electrical circuits.

What Is a Circuit Breaker?

A circuit breaker is an electrical device that protects an electrical circuit from damage caused by excess current from an overload or short-circuit. Circuit breakers come in different styles, but all work similarly by interrupting the flow of electricity once the current reaches a certain threshold. Circuit breakers act as safety devices by automatically shutting off the flow of electricity when a fault or overload occurs, thus protecting the equipment and wiring in the circuit. By doing so, they help prevent fires and other electrical damages.

R21-4-2.00A-34067-2-V Application Field and Working Principle

The R21-4-2.00A-34067-2-V circuit breaker is a compact, lightweight and highly efficient device that is suitable for a variety of residential, commercial and industrial applications. This circuit breaker can be used as a safety switch, preventative protection, or a power-distribution switch. It also serves as a powerful energy-saving tool, helping to reduce energy waste and cost by preventing the overheating of electrical equipment.

The R21-4-2.00A-34067-2-V circuit breaker is designed to automatically detect and shut off the current when the system exceeds its amperage rating. When the circuit breaker detects an overload situation, it will quickly shut off the electricity and help to protect against dangerous situations, such as fire. In order to do this, the circuit breaker uses a heat-sensitive device called a bimetal strip, which expands and contracts when heated or cooled. If the device detects excessive heat, it will expand and thus trigger the circuit breaker to disconnect the circuit. This same mechanism is responsible for resetting the circuit breaker when the overload situation has been resolved.

The R21-4-2.00A-34067-2-V circuit breaker is a perfect choice for a wide range of residential, commercial and industrial applications. It is easy to install and includes a variety of features to meet your specific needs. Additionally, it is UL listed, which means it has been tested to meet the highest safety standards.

Conclusion

The R21-4-2.00A-34067-2-V circuit breaker is a reliable, powerful and efficient device designed to help protect electrical equipment and wiring from overloads and short circuits. It has a broad range of residential, commercial and industrial applications, and is UL listed to guarantee quality and safety. Whether you are looking for a preventive protection switch or an energy-saving device, the R21-4-2.00A-34067-2-V circuit breaker is the perfect solution.
