Circuit Breakers: R21-2-10.0A-R01IH-V Application Field and working Principle

Circuit breakers are vital components of the electrical grid and are used to protect devices and circuitry from overloads. The R21-2-10.0A-R01IH-V circuit breaker is a type of miniature molded case circuit breaker that is typically used for residential and light commercial applications. This article will discuss the application field and working principle of this circuit breaker as well as explaining how to install and troubleshoot it.

Application Field

The R21-2-10.0A-R01IH-V circuit breaker is designed for single pole applications and is suitable for both residential and light commercial applications. This circuit breaker is rated at 10 amps and is UL listed for use in branch circuits supplying lighting, air conditioning, and heating equipment. It is also CSA approved and can be used in a variety of industrial applications.

The R21-2-10.0A-R01IH-V is a Type 2 circuit breaker and is suitable for branch circuit protection in accordance with the National Electrical Code. It features a test button that allows you to manually check the tripping of the device. This circuit breaker also has a thermal-magnetic trip unit for enhanced protection against short circuits.

Working Principle

The R21-2-10.0A-R01IH-V circuit breaker works according to the thermal-magnetic principle. Both the thermal and magnetic mechanisms work together to protect the circuit from short circuits and overloads. The thermal part of the breaker works by detecting the current and temperature of the circuit. If the current goes beyond the breaker’s rated amperage or the temperature rises above a set level, the thermal part will trip the breaker and shut off the power. The magnetic part of the breaker works by detecting the amount of current passing through the breaker. If the current passes over the breaker’s rated amperage, the magnetic part of the breaker will trip the breaker and shut off the power.

The R21-2-10.0A-R01IH-V circuit breaker also features a visual indicator that will show when it has tripped. This indicator is a small red circle at the top of the breaker that will be illuminated when the breaker has tripped. This allows you to quickly identify and troubleshoot any electrical issues.

Installation and Troubleshooting

To install the R21-2-10.0A-R01IH-V circuit breaker, the first step is to turn off the power to the circuit you are installing the breaker on. Once the power is off, remove the panel cover and locate the upper right corner where the line and load wires enter. Connect the line wires to the left side of the breaker and the load wires to the right side of the breaker. Securely connect all the wires by tightening the terminal screws. Finally, mount the breaker into the panel and turn the power back on.

Troubleshooting this circuit breaker is relatively easy as it has a visual indicator as mentioned earlier. If the indicator is illuminated, it means the breaker has tripped. To reset it, you must turn the breaker to the off position and then back to the on position. If the indicator does not turn off, then it means there is a more serious issue and you may need to call an electrician to take a look.

In conclusion, the R21-2-10.0A-R01IH-V circuit breaker is a type of miniature molded case circuit breaker typically used for residential and light commercial applications. It works on a thermal-magnetic principle and features a visual indicator that shows when it has tripped. Installing and troubleshooting this breaker is relatively easy and can be done without the help of an electrician.
