Circuit breakers are essential components of electrical systems and are used to protect the circuit, equipment, and people by interrupting the electrical circuit when an overload or short circuit is detected. The R21-62-15.0A-37175-1-V is one of the many circuit breakers on the market. In this article, we will discuss the application field and working principle of this particular model.

Application Field

The R21-62-15.0A-37175-1-V is a single pole circuit breaker with a voltage rating of 0-240VAC and an amperage rating of 15 amps. This makes the circuit breaker suitable for residential and commercial applications with light to medium electrical loads. Furthermore, the circuit breaker has an interrupting rating of 10,000 AIC, making it suitable for short circuit protection in low voltage systems. The circuit breaker is UL listed and meets UL 1077 supplemental protection standards.

Working Principle

The working principle of a circuit breaker is generally the same regardless of the model. The R21-62-15.0A-37175-1-V is no exception. It is designed to detect an overload or short circuit in the electrical circuit and interrupt the flow of electricity. To do this, the circuit breaker has an internal solenoid coil, which is activated when an overload or short circuit is detected. When the coil is activated, it triggers the circuit breaker\'s tripping mechanism which then breaks the connection between the electrical circuit and the power source.

The circuit breaker also has thermal and magnetic tripping mechanisms. The thermal tripping mechanism is used to detect and protect against electrical overloads. It works by measuring the temperature of the internal components. When the temperature exceeds a certain threshold, the circuit breaker trips and breaks the connection. The magnetic tripping mechanism is used to detect and protect against short circuits. It works by measuring the amount of current flowing through the circuit breaker. When the current reaches a certain threshold, the circuit breaker trips and breaks the connection.

In addition to its tripping mechanisms, the circuit breaker also has a manual reset feature. This feature allows the user to manually reset the circuit breaker after it trips. This is helpful in situations where the cause of the trip has been resolved and it is safe to reset the breaker.

Conclusion

The R21-62-15.0A-37175-1-V is a single pole circuit breaker with an amperage rating of 15 amps and a voltage rating of 0-240VAC. It is suitable for residential and commercial applications with light to medium electrical loads and has a UL rating of 10,000 AIC. In addition to its thermal and magnetic tripping mechanisms, the circuit breaker also has a manual reset feature. All of these features make the R21-62-15.0A-37175-1-V a reliable and effective circuit breaker for home and commercial applications.
