PR21-4-20.0A-XX-V

Circuit Breakers are essential components that help protect electrical systems from damage due to an overcurrent situation. The PR21-4-20.0A-XX-V is a type of Circuit Breaker that helps protect circuits while allowing them to be safely used in a variety of applications. This article will discuss the application fields and working principle of the PR21-4-20.0A-XX-V.

Application Fields

The PR21-4-20.0A-XX-V is typically used in applications that require a circuit breaker with a current rating of up to 20.0A. These applications include residential, commercial and industrial settings, including wiring and load centers, HVAC systems, pumps, motors, appliances and lighting systems. The PR21-4-20.0A-XX-V is ULrated for compatibility with these types of applications and for its ensuring safety against an overcurrent situation.

Working Principle

The working principle of the PR21-4-20.0A-XX-V is relatively simple. Its function is to automatically switch the circuit off when it detects a current that is higher than its rating. This is done using a current sensitive trip device, which is essentially a switch. When the circuit exceeds its rating, the switch is tripped, breaking the circuit and preventing any further damage to the system. When the power is restored, the switch will reset itself and the circuitbreaker will be ready to be used once more.

Conclusion

The PR21-4-20.0A-XX-V is an essential component for any electrical system that requires a circuit breaker with an adjustable current rating of up to 20.0A. It is versatile enough to be used in a variety of applications. Its working principle makes it highly reliable and ensures that it will protect against an overcurrent situation.
