Circuit breakers are important components in an electrical system or equipment using electrical power. They are designed to prevent overloads by detecting when the current flowing through the circuit is too high. If a circuit breaker detects an overload, it will open the circuit, interrupting the flow of current. This protects the circuit from damage that would otherwise occur from excessive current. It also protects people nearby from electric shock.R21-2-10.0A-B01IV-V is one type of circuit breaker. It is a two-pole, 10-amp thermal-magnetic circuit breaker with a voltage rating of 120/240 volts. It is a UL listed circuit breaker and is suitable for use as a branch circuit breaker in residential and light commercial applications.

The R21-2-10.0A-B01IV-V circuit breaker is a thermal-magnetic breaker, which means it is combination of a thermal (overload) circuit breaker and a magnetic (short-circuit) circuit breaker. The thermal element is made up of a bimetal strip which is the sensing device. If a current overload occurs, the bimetal quickly heats up and expands, causing it to flex and open the circuit breaker, interrupting the flow of current. The thermal element can be reset by simply pushing the reset button.

The R21-2-10.0A-B01IV-V also contains a magnetic element which responds to short-circuit currents. The magnetic element contains a solenoid which is made up of a coil of wire and a soft iron core. When a short circuit occurs, a large amount of current flows through the circuit. This generates a magnetic field around the solenoid which then attracts the iron core, causing it to move rapidly and open the circuit breaker, thus protecting the circuit and users from electric shock. The magnetic element cannot be reset and the circuit breaker must be replaced.

R21-2-10.0A-B01IV-V circuit breakers are designed for use in residential and light commercial applications. They are suitable for use as branch circuit breakers and provide protection from overload and short circuit currents. They are easy to install and use, and are reliable and safe for a variety of applications. In addition, the R21-2-10.0A-B01IV-V circuit breaker has a UL listing, meaning it has been tested and approved for use in the United States.

In summary, the R21-2-10.0A-B01IV-V circuit breaker is a two-pole, 10-amp thermal-magnetic breaker with a 120/240 voltage rating. It is suitable for use in residential and light commercial applications as a branch circuit breaker. It provides protection from overload and short-circuit currents and has a UL listing indicating it has met the safety standards of the United States. This circuit breaker is reliable, safe, and easy to install and use.
