The R21-2-20.0A-B188EV is a type of circuit breaker, a device used to prevent hazardous levels of electrical current from passing through a circuit. It is typically used in industrial settings, such as factories, where large amounts of electricity are required and protection from overcurrent is necessary. The R21-2-20.0A-B188EV is a thermal-magnetic circuit breaker and it functions on the basis of both temperature and magnetic forces.

The principle of operation is simple yet effective. The breaker contains a thermal element, which is designed to respond to high temperature levels, as well as a magnetic element, which is designed to respond to high levels of current. When a surge of current attempts to pass through the circuit, the thermal element is triggered and the breaker trips, breaking the electrical connection and preventing the surge from passing any further.

On the other hand, when a thermal overload occurs, the breaker does not trip immediately. Instead, the thermal element slowly raises the temperature in the circuit, operating as an early warning sign. If the temperature continues to rise, then eventually the magnetic element is triggered and the breaker trips.

The R21-2-20.0A-B188EV has a wide range of applications, and can be used in many kinds of industrial settings. It is commonly used in power plants, manufacturing facilities, hospitals, and industrial environments. It is designed to provide circuit protection in areas where a large amount of current is required, and where strong protection from short circuits and electrical overloads is needed.

This type of breaker is built to a high standard, with a long-lasting and reliable design. It is designed to be easy to use and to maintain. The breaker can also be reset quickly and easily, allowing it to be used over and over again.

The R21-2-20.0A-B188EV is a reliable and efficient device, and it is well suited for use in a variety of industrial settings. It is an excellent choice for providing protection from overcurrents, short circuits and electrical overloads, and it can help to ensure the safe and efficient operation of any industrial facility.
