Circuit breakers are an essential safety device and are used all over the world to prevent overloads and short circuits. R21-2-20.0A-B121CV-S is one of these circuit breakers, specifically designed for use in data processing, telecommunications, electronic equipment protection, automatic control systems and other applications.

Circuit breakers are designed to protect from overcurrent, short circuits and ground faults. R21-2-20.0A-B121CV-S circuit breakers are designed to prevent the interruption of service due to overcurrents, short circuits and excessive temperatures. When an overcurrent, short circuit or temperature-related fault is detected, the circuit breaker will automatically disconnect the circuit to prevent damage.

R21-2-20.0A-B121CV-S circuit breakers are highly reliable and efficient when it comes to protecting electrical systems. They are designed to open quickly in the event of an overload, short circuit or ground fault, and to re-close when the fault is eliminated. They are reusable and can be reset after tripping.

The working principle of R21-2-20.0A-B121CV-S circuit breakers is fairly straightforward. The circuit breaker is equipped with a thermally-sensitive current-limiting element which will heat up as the current increases. When the temperature reaches a certain point, it opens the circuit, preventing further increase in current. This allows the circuit breaker to safely protect itself, as well as the electrical system, from short circuits and overloads.

R21-2-20.0A-B121CV-S circuit breakers come in a variety of configurations, including single-pole, double-pole, and three-pole. As their power rating is 20 amps, they are suitable for use in many different applications, from manufacturing, industrial, commercial and residential settings.

R21-2-20.0A-B121CV-S circuit breakers offer superior safety and reliability. They are UL listed and CSA certified, ensuring that they comply with all safety regulations. They are also equipped with an internal diagnostic system which monitors their internal components and can detect any potential faults.

In conclusion, R21-2-20.0A-B121CV-S circuit breakers are an excellent choice for protecting electrical systems. They offer extraordinary reliability and protection, and are suitable for a wide range of applications. Their working principle is easy to understand, and they meet all safety regulations.
