Circuit breakers protect electrical circuits and prevent fire by either completely breaking the circuit or reducing its current flow. R21-1-15.0A-R123CV-V is a circuit breaker that provides protection against fixed overloads, while allowing infrequent interruptions of loads during non-emergency conditions. It has a wide range of applications in both residential and industrial settings.

Features of R21-1-15.0A-R123CV-V

The R21-1-15.0A-R123CV-V circuit breaker is designed for residential and industrial applications. This device provides the following features:

• Good performance in alternating current (AC) applications, with protection against fixed overloads
• Frequency rating of 50/60 Hz
• Circuit terminals designed for easy installation
• Quick fault detection and disconnection, preventing further damage to the circuit
• Operating temperature range of -10 to +50 degrees Celsius
• Trip delay time adjustable between 0 and 5 seconds
• Ability to withstand high mechanical forces
• IP20 protected design

Features of R21-1-15.0A-R123CV-V

The R21-1-15.0A-R123CV-V circuit breaker works by automatically breaking or interrupting power whenever an overload occurs. This is done through the use of bimetallic strips that sense the heat caused by an overload and react by opening the circuit. When the overload is removed, a reset switch or button must be pressed in order to restore the power supply.

Additionally, this circuit breaker is designed specifically for AC applications, and is designed to protect against fixed overloads. This means that it will protect against the amount of power drawn from the circuit, but will not be able to detect and disconnect a circuit in a situation where the current is fluctuating or changing. This is why it is best suited for residential applications, where the amount of draw is relatively constant.

The R21-1-15.0A-R123CV-V circuit breaker also has a quick trip delay time. This is an adjustable feature that allows users to adjust the length of time it takes for the circuit breaker to disconnect the power. This allows users to prevent damage to their devices by ensuring that the circuit breaker trips quickly in the case of an overload. This can be adjusted between 0 and 5 seconds.

Finally, the circuit breaker is also designed to withstand high mechanical forces. In the event of a power surge or other sudden increase in the current draw, the circuit breaker is designed to remain intact and activate quickly enough to protect the connected devices from damage.

Conclusion

The R21-1-15.0A-R123CV-V circuit breaker is a versatile device that provides protection against fixed overloads in a wide range of residential and industrial applications. It features a trip delay time adjustable by the user, frequency rating of 50/60 Hz, and the ability to withstand high mechanical forces. By providing quick detection of faults and disconnection of loads during non-emergency conditions, this circuit breaker can protect expensive electrical components from being damaged or destroyed by an overload.
