Circuit Breakers

Circuit Breakrs allow electricians to protect circuits and provide safety measures for electrical designs. They are used for many applications, and the most commonly used breakers are the type identified by the code 219-4-4442-4-V. Here we will review the application field and working principle of these breakers.

Application Field

The 219-4-4442-4-V circuit breakers are generally used for domestic and light commercial applications. They are designed to open and close the circuit in order to protect against overcurrent, occurring due to short-circuits or overloads. The more common applications include residential and small business buildings, apartments, condominiums, factories, and other facilities.

Working Principle

The 219-4-4442-4-V breaker is designed to detect an overcurrent and automatically open the circuit when the current exceeds the current setting. The circuit breaker works by using an electromagnet to create a magnetic field when a current flows through the circuit. This field trips the internal trip mechanism which causes the breaker to open the circuit. These breakers also have a thermal trip element, which trips the breaker when the motors or other appliances draw more current then they are rated for.

The breaker also contains a handle that can be used to manually open or close the circuit. This is generally used when the breaker needs to be reset, or when maintenance is required. In addition to the handle, these circuit breakers are equipped with a visible test button, which allows the user to check if the breaker is working properly. Finally, these circuits come with a red deactivation switch, which physically prevents the breaker from tripping when the test button is pressed.

Conclusion

The 219-4-4442-4-V circuit breaker is a great choice for residential and commercial use, as it protects the circuit from overcurrent and overload. Furthermore, it’s easy to test, as it has a visible test button, and reset with a manual handle. It also comes with a deactivation switch, which prevents accidental tripping. The 219-4-4442-4-V circuit breaker is tested and certified as being safe for use in both commercial and domestic applications.
