Circuit breakers are devices that are used to protect electronic devices from damage caused by overcurrent, overload, and short circuits. They can also be used to protect personnel from electrical shock. The R21-2-10.0A-R107CV-V is a type of circuit breaker that is commonly used in industrial, commercial, and residential applications.

The R21-2-10.0A-R107CV-V consists of an adjustable overload setting and a temperature limit switch with a temperature setting of 125°C. In the event of an overcurrent, or a short circuit, the circuit breaker trips, disconnecting the system from the power supply. In addition, the temperature limit switch will trip if the temperature exceeds the preset limit, protecting the equipment and personnel from potential risks.

The adjustable overload setting allows users to select a current capacity that is appropriate for the application. The overload setting might need to be adjusted depending on the type of appliance or other device connected to the circuit. It is important to ensure that the overload setting is not set too low, or too high, as this could cause damage to the appliances connected to the circuit.

The temperature limit switch protects the equipment connected to the circuit by tripping the circuit if the temperature of the surrounding environment increases to a level that is unsafe for the equipment. This is especially important for sensitive electronic devices, as these can be quickly and irreversibly damaged by elevated temperatures.

In addition to the overload protection and temperature limit switch, the R21-2-10.0A-R107CV-V also includes an electromechanical trip latch. This latch is used to prevent the circuit breaker from being subjected to frequent on and offs, which can reduce its effectiveness and lifespan. The latch also prevents the circuit breaker from being switched off if the overload protection has been activated.

The main advantages of the R21-2-10.0A-R107CV-V are its adjustable overload settings and temperature limit switch. These features provide effective protection against overcurrent, overload, and short circuits, while also protecting personnel from electrical shock. In addition, the electromechanical trip latch ensures that the circuit breaker remains effective and long-lasting, even when used frequently. This makes the R21-2-10.0A-R107CV-V a suitable choice for industrial, commercial, and residential applications.
