R21-2-20.0A-30147-1-V

R21-2-20.0A-30147-1-V is an example of a circuit breaker. Circuit breakers are safety devices used to protect and deactivate electrical circuits when too much current flows through them. They are typically used in household and industrial applications and are available in a variety of sizes and designations. As the name implies, circuit breakers are designed to "break" or deactivate an electrical circuit when a certain current threshold is exceeded.

Circuit breakers are an important part of any electrical system. They provide protection against electric shock, overvoltages, excessive current, short circuits and other problems. In addition, they are used to disconnect electrical systems in case of an emergency. This allows power to be quickly switched off and, if needed, prevents fires from occurring.

R21-2-20.0A-30147-1-V circuit breaker is a highly reliable device that is capable of switching off high electric currents safely. It has a rating of 20.0A and is designed for a wide variety of applications. It is a highly reliable device owing to its special extra thermal protection and overload protection. Its extra thermal protection trips the circuitry to protect it against excessive temperatures, while the overload protection trips the circuitry when the flow of electricity exceeds the stated threshold.

Moreover, R21-2-20.0A-30147-1-V circuit breaker features adjustable settings that work in tandem with temperature switches. Thanks to its adjustable settings, it can be used in a variety of applications and environments, including water heaters, air conditioners, lighting and circuits with high current loads. It is also capable of switching off large electrical currents such as those used in welding and plasma cutting.

In conclusion, R21-2-20.0A-30147-1-V is an example of a reliable and versatile circuit breaker. It is designed to protect circuits against excessive current and temperatures. Its adjustable settings allow for customization to fit in different applications and environments. With its high-tech protective design, it is an excellent choice for a variety of applications.
